A compiler is a program used to turn source code into machine code. The source code that describes a C program is compiled using a compiler before being run on a computer. In order to understand what is a compiler in computer science, it is helpful to first understand how compilers work. Once one has a better understanding of how compilers work, it will be easier to understand what is a compiler and what it does.

A computer program is a collection of instructions that are given and a corresponding execution code. Instructions are words that tell the computer how to accomplish the desired result. The word or words are referred to as source code. Each instruction consists of one or more source code words. The computer then uses the compiled code and the output to determine what the intended result should be.

In a program, an instruction is executed once for each source code word that is generated. Each such word is called a program instruction. In order for the computer to execute the desired program, the computer must search the memory for the matching instruction. If the search results in no match, the computer stops and the execution is ended. The computer ends the program at the end of the instruction.

Compilers compile source code into machine code. The source code is written into a series of binary instructions. Each instruction has a corresponding binary code that is interpreted into machine code by the compiler. The execute the compiled code and results in machine code. In order for the computer to effectively process the code, it must have the appropriate software to perform the compile task. Typically, any computer operating system that supports compiled language will have a compiler.

A C compiler is used to translate a program into C language. Programs written in C are run on a C- Simulator, which is a virtual machine that duplicates the hardware of the computer CPU. The C- Simulator allows the programmer to create a C program from the top-level code that is generated from the program code. In effect, the C- Simulator is a translation translator from a high-level programming language into C.

A C compiler is not the same as an optimizing C compiler. An optimizing C compiler optimizes a program by removing unnecessary expressions from the source code. A C compiler does not translate source code into machine code. Instead, the C compiler generates machine code from the source code. Optimizing C programs is typically applied to the applications’ shared library or static data.

A C compiler is often used with a large variety of languages. Compiler technologies vary significantly in scope, functionality, licensing and complexity of implementation. There are also multiple interface types that allow for various implementation strategies. For instance, one approach that allows multiple implementations of a C compiler has been dubbed the “paradigm” by those in the industry. This means that there are now two major mainstream implementations of C: the Microsoft Windows-based “MSVC” and the Unix-like” Perl” C compiler.

Although the C language has come a long way in recent years, many people are still unfamiliar with its syntax and design. It can be quite confusing at first for someone who is not used to it. However, once you get the hang of C and begin to experience its power, you will wonder how you ever did without it. One of the great things about C is that it is a very flexible language, allowing for a tremendous amount of customization. If you have a need to create a new program but don’t know which programming language to use, then C can be your answer. There are so many uses for C that no other programming language comes close in number of features.
