print addition of 2 default numbers

Program to print addition of 2 default numbers

Let’s see how to write this C program

#include<conio.h>                   

#include<stdio.h>

int main()                                   

{

int first= 10,second=12;       

int result;   

              

result = first+second;

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

getch();

return 0;

}

Explanation of the program

Int first=10,second=12;

This statement we going to initialize the two variables in the memory named as first and second which holds the default values of 10 and 12 respectively.

int result;

Here we initialize our 3^rd variable named as result. This currently holds no value

result=first+second;

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

Getch()and return 0

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
