Manipulating specific hardware the way you want (more access or control), I guess other high-level languages don’t have this feature. It takes additional translation times to translate the source to machine code. (d) Hard/ difficult and slower to code and debug program instruction codes. As time passed, more levels of this translation process were added, resulting in high level languages, the syntax of which looks more like a natural language such as English. In high-level language programs run independently of processor type. Answers (a) Does not allow the use of program control structures which encourage modules. What are the disadvantages of C programming language. High-level languages need to be converted to low-level and hence, have slower execution and also a larger file size than the low-level counterparts for the same code. (a) High level languages are providers of a better user interface to interact with. C/C++ are high level languages and Linux's kernel for example is written in C++ (witch also supports machine code to be inserted). High-level languages have to give extra instructions to run code on the computer. High-level instructions: Program development is faster Fewer lines of code Program maintenance is easier Low-level languages will produce an OS that is smaller, leaner, and runs faster, but be much more difficult to create and maintain. (e) Program instruction codes are long. Disadvantages of assembly language “One line of C equals 4 or 5 lines of Assembly”, that’s a bad thing to read or hear, right? (d) High level languages are user friendly than low level languages. And, also a structural oriented language and functional language. Disadvantages. Advantages Disadvantages High-level languages are user-friendly A high-level language has to be translated into the machine language by a translator, which takes up time They are easier to learn They are easier to maintain They are problem-oriented rather than 'machine'-based A program written in a high-level language can be translated into many machine languages and can run on any … A used translator is a compiler or interpreter. High-level languages are user-friendly A high-level language has to be translated into the machine language by a translator, which takes up time. Disadvantages of High Level Languages: You need some sort of compiler to get the HLL to LLL; In some cases (e.g. Advantages and disadvantages of low level language: Advantages: Fast to run as no need of specific translator. As others have mentioned, lower level language allows you to have more direct control to the hardware. An assembler translates assembly language into machine code.i. The main advantage of high-level languages over low-level languages is that they are easier to read, write, and maintain. So, there is a trade-off between high-level and low-level programming languages. In case when you need to make basic calls, still system calls are possible. However, learning a foreign language has some disadvantages, too, such as the cost of language courses and the time it requires. These languages do not interact directly with hardware. Some prominent examples are PASCAL, FORTRAN, C++ etc. High-level language (1958’s to 1985’s) It is a third-generation programming language or procedural language. Java / C#) you have an interpreter in between which also consumes resources (but can also optimize itself while running the program!) Weighing the costs and benefits can help you decide whether learning a foreign language is the right choice for you. Cost. A high-level language is a programming language designed to simplify computer programming. Advantages of High Level Languages Higher level languages have a major advantage over machine and assembly languages that higher level languages are easy to learn and use. High level programs are comparatively slower than low level programs. It is because that they are similar to the languages used by us in our day to day life. Development time: Writing code in assembly language takes much longer time than in a high level language. They are simple and machines can understand. Highlight the disadvantages of low level languages. Learning a foreign language can be expensive, especially if you take college courses or pay for private tutoring. Not all high level languages support low level I/O. Disadvantages of low level languages. High level languages are similar to the human language. What are some advantages and disadvantages of using a high level programming language (e.g. Disadvantages. (c) High level languages are machine independent. Disadvantages: It is almost impossible to find and correct errors. Low level languages are related to hardware. A third-generation programming language (3GL) is a high-level computer programming language that tends to be more machine-independent and programmer-friendly than the machine code of the first-generation and assembly languages of the second-generation, while having a less specific focus to the fourth and fifth generations. Advantages and Disadvantages of C++ language. High level language is abbreviated as HLL. (c) Does not increase programmer productivity. (b) Does not have better interface. The disadvantages of a low level language are typically cited as being relatively difficult to read, harder to debug, and requires more development time than a high level language. High Level Languages have a syntax similar to the English Language so uses a compiler or an interpreter to convert the human readable program to computer readable machine code. High Level Languages. 1.Programs developed using low level languages are machine dependent and are … High level languages – advantages and disadvantages. When we talk about high level languages, these are programming languages. 2. Reliability and security: It is easy to make errors in assembly code.The assembler is not checking if the calling conventions and register save conventions are obeyed. Why C is a Middle level programming language . If we leave the kernel alone (witch is the most importent part in the OS), some other modules of the OS can be written in , let's say Basic or even Haskell. What do you mean by high level, middle level and low level languages and give an example for each. Easy to learn and use (reliability). C++ is based on the C language, and it was developed in early 1980's by Bjarne Stroustrup at AT&T Bell Laboratories, Here "++" use for the extension because "++" is a syntactic construct used in C to increment a variable.Most of the C++ content is the super-set of "C", Due to this extension most C programs can be compiled using a C++ compiler. High-level languages are basically symbolic languages that use English words and/or mathematical symbols rather than mnemonic codes. The advantages and disadvantages of both high-level and low-level languages are given below. (b) High level languages are allowed the use of program control structures which help programmers develop programs using modular approach. Programming languages are therefore spread over a spectrum, with low level languages closer to machine code and high level languages furthest away from it. The programmer has unlimited access to the working of a computer system. High-level languages require translator software that will be held in RAM when a program is executed. Assembly language consists of mnemonics for machine opcodes so assemblers perform a 1:1 translation from mnemonics to a direct instruction. High-level language programs are portable. Email This BlogThis! Ans. 4.Low level languages provide direct manipulation of computer registers and storage. 5.It can directly communicate with hardware devices. Therefore, High Level Languages takes time to execute. Assembler []. High level language provides higher level of abstraction from machine language. (f) They are not user friendly. In my perspective High Level Language has not got any Disadvantages. An OS written in a high-level language (as opposed to a low-level language, such as assembly language) will require far less code, be easier to create and maintain, and will find a larger pool of qualified programmers to work on the project. Some advantages and disadvantages of this language as follows: Advantages: It is machine independent (portability). Theoretically it makes it easier to talk with hardware devices and I/O ports. It is useful for programming OS, drivers, hardware control and high performance applications. Disadvantages of High level language. Compared to low level programs, they are generally less memory efficient. This is one-to-many translation and not one-to-one as in the case of assembly language. (Although some programs could still have a few machine-dependent details, they can be used with little or no modifications on other types of machines.) High level languages are enhancing easy communication with the system. High level languages are written in a form that is close to our human language, enabling to programmer to just focus on the problem being solved. Posted by Sakash Agrawal at Thursday, February 16, 2012. C Programming language tutorial, Sample C programs, C++ Programs, Java Program, Interview Questions, C graphics programming, Data Structures, Binary Tree, Linked List, Stack, Queue, Header … The important feature about such high level languages is that they allow the programmer to write programs for all types of computers and systems. The disadvantages of assembly languages when compared to the high level languages are as follows; 1. It is "high-level" since it is several steps removed from the actual code run on a computer's processor.High-level source code contains easy-to-read syntax that is later converted into a low-level language, which can be recognized and run by a specific CPU. For example: LDA #4 converts to 0001001000100100. Every instruction which the programmer writes in a high-level language is translated into many machine language instructions. High Level Languages are also not memory efficient. Conversely, one instruction in a high level language will translate to one or more instructions at machine level. In Microprocessors only op-codes are being used. There are two categories of programming languages, high level and low level. Unlike low level languages, high level languages are programmers friendly, easy to code, debug and maintain. 2] High Level Language. Get to know how the CPU and Memory work. Thus can be better for writing device drivers. Code of assembly language is difficult to understand and debug than a high-level. They are easier to learn They are … They are similar to English and use English vocabulary and well-known symbols The object code generated by a translator might be inefficient compared to an equivalent assembly language program. Performance and accuracy of assembly language code are better than a high-level. When we think about computer programmers, we are probably thinking about people who write in high-level programming languages. Advantages of assembly language. Since you are writing at machine level you control the level of performance of the code created - in a high level language you have to count on the compiler to optimize.
