Answer 1

#include <iostream>
#include <cmath>


using namespace std;


int main()
{
    double numbers1, numbers2, numbers3;
    int int1, int2, int3;
    //1) prompts the user to input 3 decimal numbers (with a fraction part)
    cout << "Please enter 3 decimal numbers: \n";
    cin >> numbers1 >> numbers2 >> numbers3;
	//2) Prints the three decimal numbers.
    cout<<endl << numbers1 << " " << numbers2 << " " << numbers3<<endl;
    //3) Converts each decimal number to the nearest integer.
    int1 = round(numbers1);
    int2 = round(numbers2);
    int3 = round(numbers3);
    //4) Prints the three converted numbers.
	cout<<endl<<"The three converted numbers: "<<endl;
	cout << int1 << " " << int2 << " " << int3<<endl;


    return 0;
