C PROGRAM TO ADD TWO NUMBERS / INTEGERS

Simple c program for adding two numbers and its explanation:
PROGRAM:
#include<stdio.h>
int main()
{
     int x;
     int y;
     int result;
     printf("\n Enter the first number to be added: ");
     scanf("%d",&x);
     printf("\n Enter the second number to be added: ");
     scanf("%d",&y);
     result = x + y;
     printf("\n The sum of two numbers is: %d\n",result);
     return 0;
}

Sample Output:
( using GNU GCC Compiler with Code Blocks IDE )

  
EXPLANATION for the above program :     

 1) The #include <stdio.h> includes the file stdio.h into your       code so it knows what the 
functions such as  printf() mean.

 2) main() is the main function in which you write most of your       code .  int is the default 
return type of main function.

 3) int x; , int y; , and int result. the int stands for integer     or a number 
(no decimal points you need a float for that) the     X and Y are the numbers you are adding together and result is     the result of the numbers.

 4) printf("\nEnter the first number to be added: ");
    scanf("%d",&x); the Printf() prints the text, Enter the first     number to be added: , 
onto the screen and the         
    scanf("%d",&x); looks for the number input from the keyboard     for x.

 5) printf("\n Enter the second number to be added: ");
    scanf("%d",&y); do the same as the last 2 lines except it         looks for the  value for y instead of x.

 6) result = x + y; that adds the values of X and Y and stores       the result in the 
variable result.

 7) printf(" The sum of two numbers: %d\n",result);  that prints     the result on the screen  
    return(0); tells the OS that the program ended  successfully.
