Answer 1

#include <iostream>
using namespace std;


int main() {
    double d1, d2, d3, d4, d5;


    cout << "Enter 3 decimal numbers: ";
    cin >> d1 >> d2 >> d3;


    d4 = 3.1415926;
    d5 = 2.718281828;


    int i1, i2, i3, i4, i5;
    i1 = static_cast<int>(d1+0.5);
    i2 = static_cast<int>(d2+0.5);
    i3 = static_cast<int>(d3+0.5);
    i4 = static_cast<int>(d4+0.5);
    i5 = static_cast<int>(d5+0.5);


    cout << i1 << " " << i2 << " " << i3
         << " " << i4 << " " << i5 << endl;
    
    return 0;
}
