Program:

#include"stdio.h"
 void main()
	{
	int num1, num2, sum; 
	printf("Enter two no: ");
 	scanf("%d%d",&num1,&num2);
	sum = num1 + num2;
        printf("sum=%d \n", sum );    
}

Output:

Enter two no: 2 3
sum=5
Press any key to continue . . .

Explanation:

Algorithm:

  • Step 1: Start
  • Step 2: Declare variable number1, number2 and sum
  • Step 3: Read Variable number1, number2
  • Step 4: Perform operation (sum= number1+ number2)
  • Step 5: Print sum variable
  • Step 7: Stop

In this program, the user is asked to enter two integers. These two integers are stored in variables number1 and number2 respectively.

printf("Enter two integers: ");
scanf("%d %d", &num1, &num2);

Then, these two numbers are added using the + operator, and the result is stored in the sum variable.

sum = num1 + num2;

Finally, the printf() function is used to display the sum of numbers.

printf("sum=%d \n", sum );
