Question

C++

Suppose a user is prompted to enter four floating point number values. Write a C++ program that outputs the number of input values, the number of negative values, and the number of even values.

Answer 1

#include <iostream>

using namespace std;

int main() {
    int size;
    int evens = 0, negs = 0, count = 0, num;
    for (int i = 0; i < 4; ++i) {
        cout << "Enter a number: ";
        cin >> num;
        if (num < 0)
            ++negs;
        if (num % 2 == 0)
            ++evens;
        ++count;
    }
    cout << "Number of numbers = " << count << endl;
    cout << "Number of even numbers = " << evens << endl;
    cout << "Number of negative numbers = " << negs << endl;
    return 0;
}
