In the following ways you can add two numbers very easily.

#include<stdio.h>

#include<conio.h>

main( )

{

int a=10,b=20,c=0;

clrscr( );

c=a+b;

printf("%d is the addition of two integers",c);

return 0;

}

or

#include<stdio.h>

#include<conio.h>

main( )

{

int a,b,c=0;

clrscr( );

printf("enter first number ");

scanf("%d",&a);

printf("enter second number ");

scanf("%d",&b);

c=a+b;

printf("%d is the addition of two integers",c);

return 0;

}

or

#include<stdio.h>

#include<conio.h>

main( )

{

int a,b,c=0;

clrscr( );

printf("enter two numbers ");

scanf("%d%d",&a,&b);

c=a+b;

printf("%d is the addition of two integers",c);

return 0;

}
