How to execute C language
How to execute "C program" ?
The C program execute with the help of translator software. Which reads the code and find error if there is any mistake and that code convert into computer language/binary language which is the form of 0 and 1.
Translator software is a system software which is translate one programming language to an other programming language.
Types of translator software:
There are following types:-Compiler:- It is a system software that convert entire high-level language into machine language, then execute the code.
For example:- GCC (for C,C++), Javac (for Java).
Interpreter:- It is a system software that execute the code line by line, without convert into the machine language. Developed by John Backus and his team in 1957.
For example:- Python Interpreter, Ruby MRI, Node.js.
Assembler:- It is a system software that is convert to assemble language ( low level code ) into machine language.
Developed by Kathleen Booth, who worked on the first assembly language and its assembler in late 1950s
For example:- NASM (Netwide Assembler), MASM (Microsoft Macro Assembler).
Decompiler:- It is a system software that Converts machine code/ bytecode back into a high-level programming language.Developed by Various teams of researchers in reverse engineering in late 1980s - 1990s.
For example :- JD-GUI (Java), Ghidra, Hex-Rays IDA Pro.
Step of Algorithm C language
- Start
- Declaration of variables
- Read the variables
- Process
- Display
- Result
- Stop
Flow chart
It is proctorial representation of an algorithm which shows the logic of problem and its allow to break the problem into parts.

Structure of C language
#preprocessor
- Including header file
- Global variables declaration
- Main()
- Declaration
- User defined function
Code
#include <stdio.h>int main() {Printf("Hello world!");return 0;}
Result :- Hello world!
