Description

In this program, program will take two number as input and give sum of the two number
as output. The first input stored in variable firstNumber and second input stored in
variable secondNumber. The variables firstNumber and secondNumber are added using the 
arithmetic operator + and the result is stored in the variable sum.
example : firstNumber = 8
          secondNumber = 10
	      sum = 18

C/C++

/* C Program to add two numbers */
//Save it as AddTwoNumber.c

#include<stdio.h>
int main(){

    int firstNumber, secondNumber, sum;

    printf("Enter the first number : ");
    scanf("%d",&firstNumber);

    printf("Enter the second number : ");
    scanf("%d",&secondNumber);

    sum = firstNumber + secondNumber;

    printf("The sum of %d and %d is %d",firstNumber,secondNumber,sum);

    return 0;
}

Input:
Enter the first number : 
15
Enter the second number : 
2

Output:
The sum of 15 and 2 is 17

        System.out.println("Enter the first number : ");
        firstNumber = scanner.nextInt();

        System.out.println("Enter the second number : ");
        secondNumber = scanner.nextInt();

        sum = firstNumber + secondNumber;

        System.out.println("The sum of "+firstNumber+" and "+secondNumber+" is "+ sum);
    }
}
