print addition of 2 user numbers

Program to print addition of 2 user numbers

Let’s see how to write this C program

#include<conio.h>

#include<stdio.h>

int main()

{

int fnum,snum,result;

printf("enter first number ");

scanf("%d",&fnum);

printf("enter second number ");

scanf("%d",&snum);

result=fnum+snum;

printf("result =%d",result);

getch();

return 0;

}

Explanation of the program

int fnum,snum,result;

Here we initialize our 3 variables named as  fnum,snum and result. These variable currently holds no value.

printf("enter first number ");

use to print as it is on the screen “enter first number“.

scanf("%d",&fnum);

allow user to enter any desired value in fnum variable.

printf("enter second number ");

use to print as it is on the screen “enter second number“.

scanf("%d",&snum);

allow user to enter any desired value in fnum variable.

result=fnum+snum;;

in this statement we add up the values of fnum and snum and then we pass that value to the variable result. Now result is holding up the addition of fnum and snum variable.

printf("result is = %d",result);

this will going to display the value stored in the variable result.

In this we combine it with the string as firstly it will display the 

“result is = “

Then the value of result is being displayed.

%d

This tells the compiler that we are going to display or read the value of integer type.

Getch(); and return 0;

Step 1:  Create the program:-

Step 2: output 

Note:  if any of the programmer is facing the problem of reappearing of the previous screen again and again

He can use the function clrscr();

It present in the conio.h header file
