Thus, the input of a compiler is a high-level language code (called source code), while its output is a machine language code (called object code).Ī compiler scans whole program and then check it for syntactic and semantic error, once the code is checked for errors, it is converted into an object code. What is a Compiler?Ī language processor that converts a program written in high-level language into machine language, entire program at once, is called a compiler. Let's start with some basics so that it will become easier to understand their differences. In this article, we will highlight all the major differences between a compiler and an interpreter.

Therefore, we convert a HLL code into machine code for execution. They are required because a computer cannot process a code written in high-level programming language like C, C++, Java, etc. Compilers and interpreters are types of system software.

Both compilers and interpreters are the language processors used to convert software codes written in high-level language into machine language codes.
