Question

C++ Write a program that reads three positive integers (> 0) from the command line (one at a time), then computes and prints the smallest entered number.

Use if-else statements for three integer comparison.

Example:

Enter an integer: 5

Enter an integer: 23

Enter an integer: 7

The smallest number is: 5

Example 2:

Enter an integer: 3

Enter an integer: 3

Enter an integer: 6

The smallest number is: 3

"The input must be positive number. The program should be able to handle multiple variables with the same value. The function must truly give a min value.

Answer 1

#include <iostream>

using namespace std;

int main() {
    int num, min;
    cout << "Enter an integer: ";
    cin >> num;
    min = num;
    cout << "Enter an integer: ";
    cin >> num;
    if (num < min) min = num;
    cout << "Enter an integer: ";
    cin >> num;
    if (num < min) min = num;
    cout << "The smallest number is: " << min << endl;
    return 0;
}
