A Simple Program to add two numbers

There are many compilers available to run C programs, some compilers come with some IDE (Integrated Development Enviroment ).

I'm using here is C-Free(Software for creating and Compiling C programs), you can use any of these like: Turbo C++, Turbo C, DJGPP ,Dev C, Dev C++, etc..

 

 

#include<stdio.h>

main()

{

int a, b, c;

printf("Enter your First Numer:\n");

scanf("%d",&a);

printf("Enter your Second Number:\n");

scanf("%d",&b);

c = a + b;

printf("Result/Addition is:\%d n",c);

}

scanf("%d",&a):- is used here to store and to refer the integer value to a variable, fro example here whatever the value is entered by the user ,stored in the variable name : a, %d is defining which type of data type is going to store in the variable 'a'. &a is used to refer that particular value, tells the compiler to store the value into the variable 'a'.
 

So what is happening here is :

 

So when you run this program it will show an output like above
