General way of writing and executing a C file

For writing a piece of code in C

Open a text editor (preferably use atom or sublime Text or VS_Code(Preffered)

Writing Code

You can use/copy sample.c file and edit in that and save that with different names

//header file
#include <stdio.h>

int main()
{
  //Your code goes here
  return 0;
}

Saving your code

Use extension .c (eg: linear.c)

Compiling the code

goto your terminal move to the directory where you have saved your file using command cd eg:

ADITYAs-MacBook-Air:~ aditya$ cd Desktop/study   //if your file is saved in the folder study inside Desktop

then press

ADITYAs-MacBook-Air:study aditya$ ls  //to confirm your file say linear.c is present or not   // this step is not required

then type

ADITYAs-MacBook-Air:study aditya$ cc filename.c   //eg: cc linear.c

You can also use Online Compiler for compiling any C program but it is not much efficient

Executing the file

type in the terminal just after compiling the code

ADITYAs-MacBook-Air:study aditya$ ./a.out 

Verifying the result

If you are getting output as expected :

then congratulations you are doing a great job

else:

Check the code once again and repeat the procedure
