Addition of two numbers in c

//www.programizbasic.blogspot.com
#include <stdio.h>

int main()
{
    int a,b,c;
    a = 10;
    b = 20;
    c = a + b;
    printf("\n");  //use for line break

    printf("Addition of two numbers : %d",c);

    printf("\n");  //use for line break

    return 0;
}

Explain:

There we do Addition of two numbers in c . So first we need three variables with integer  data types
our variables name a,b,c next we assigned all variables a = 10 , b = 20 and c we assigned a+b addition .Now we need printf function for output our addition value. write this code on your code blocks or another editor .

This is our Out put value. Please write this code not copy and paste it's not good for programmer.
