How to: Run and Compile C Programming in Ubuntu

Today I am going to show How to  Run and Compile C Programming in Ubuntu.

Just a few step and you will able to run this C in ubuntu...
so here we go ...

This is the source code of a very simple program which I am going to compile and run:
#include<stdio.h>
int main(){
int pid,ppid;
pid=getpid();


ppid=getppid();
printf("PID=%d\n,PPID=%d\n",pid,ppid);
}

To Compile:
First, save your C programs as file_name.c. Your file name can be any but the extension has to be .c. After that, open the terminal and type:


gcc<space>file_name.c<space>-o<space>file_name
I saved my file by process.c name
e.g.
gcc process.c -o process.c
If your program don’t have any errors, it will successfully compiled.
To Run:
After you successfully, compiled the program, you can see a file_name.out in the place where you save your program.
To run the program, type:

./file_name
e.g.
./process
OUTPUT: PID=1020
PPID=1052
