Program in C++ to Find the Maximum of Three Numbers

Here's a program in C++ that uses the `if` statement to find the maximum of three numbers entered by the user:

#include 
using namespace std;

int main() {
    float num1, num2, num3;

cout << "Enter three numbers: ";
    cin >> num1 >> num2 >> num3;

if (num1 >= num2 && num1 >= num3) {
        cout << "Maximum of the entered numbers: " << num1 << endl;
    } else if (num2 >= num1 && num2 >= num3) {
        cout << "Maximum of the entered numbers: " << num2 << endl;
    } else {
        cout << "Maximum of the entered numbers: " << num3 << endl;
    }

return 0;
}

This program prompts the user to enter three numbers and then compares them using the `if` statement. It checks if `num1` is greater than or equal to `num2` and `num3`, and if so, it prints `num1` as the maximum. If not, it checks if `num2` is greater than or equal to `num1` and `num3`, and if so, it prints `num2` as the maximum. Otherwise, it prints `num3` as the maximum.

Please note that this program assumes the input numbers are of type `float`. If you want to use integers instead, you can change the variable types from `float` to `int`.
