Question

Write a program that prompts the user to input five decimal numbers. The program should then add the five decimal numbers, convert the sum to the nearest integer, and print the result.Use the static_caststatement with an appropriate equation to convert the sum to an integer. Compile and run your program with the following test data:Case 1: Input: 5.1, 5.1, 5.1, 5.1, 5.1. Expected Output: 26.Case 2: Input: 5.0, 5.0, 5.0, 5.0, 5.0. Expected Output: 25

Answer 1

Answer:

#include <iostream>

#include <cmath>

using namespace std;

int main()

{

   double num1, num2, num3, num4, num5, sum = 0;

   cout << "Input: ";

   cin >> num1 >> num2 >> num3 >> num4 >> num5;

   

   sum = num1 + num2 + num3 + num4 + num5;

   cout << "Output: " << static_cast<int>(round(sum)) << endl;

   return 0;

}

Explanation:

Include cmath to use the round function

Declare the variables

Get the five numbers from the user

Sum them and assign the result to the sum

Round the sum using the round function, and convert the sum to an integer using static_cast statement

Print the sum
