What is the difference between compiler and interpreter?

compiler and interpreter

Programming code is translated for computer systems through an interpreter or compiler. In fact, with the help of an interpreter or compiler, the programmer turns a high-level programming language into a simple and understandable language. Today in Ded9 we are going to examine the differences between the interpreter system and the compiler, so stay tuned.

What is a compiler?

A compiler is a computer program that converts code written in high-level programming languages ​​into machine code. In other words, this computer program translates code that is readable to humans into binary languages ​​zero and one; In such a way that the computer system processor also understands them and finally the computer system processes the machine code to perform a specific operation.

The compiler must follow the syntax of the language in which it was written; However, the compiler is just a program and is not able to fix the errors in that program, so if something goes wrong, you must change the syntax of your software, otherwise the program will not compile properly.

What is an Interpreter?

An interpreter is a computer program that converts each line of a statement from a high-level program into machine code, which includes source code, pre-compiled code, and scripts. The performance of the compiler and the interpreter are similar; In a way, both of them actually convert high-level programming languages ​​into machine code. The compiler converts the code to machine code before running the program (making the .exe file), but the interpreter will convert the code to machine code at the same time as running the program.

The role of the compiler

The role of the interpreter

What are high-level languages?

High-level languages ​​such as C, C ++, Java, etc. are very similar to English and make the programming process easier. Of course, high-level languages ​​must go into machine language by a compiler or interpreter before execution; High-level languages ​​are also known as source code.

What is a car code?

Machine code is similar to hardware, and each computer system has its own machine language. Machine language programs are made up of binary patterns (such as 110110), each of which represents an operation that a computer system must perform. In fact, machine language programs are executable, so it is possible to run them directly.

What is Object Code?

In the process of compiling source code, the machine code generated for different processors such as Intel, AMD, and ARM will be different. In order for the code to be transferable, the source code must first be an Object Code.

They are also (like machine codes) mediocre codes that will not be understood by computer processors. Of course, these codes will go into machine codes of the platform when the program is running.
