02. Greater Number

#include <iostream>

using namespace std;

int main() {
    int firstNumber, secondNumber;
    cin >> firstNumber >> secondNumber;

    if (firstNumber > secondNumber) {
        cout << firstNumber << endl;
    }
    else {
        cout << secondNumber << endl;
    }
    return 0;
}

Решение с тернарен оператор:

#include <iostream>

using namespace std;

int main() {
    int firstNumber, secondNumber;
    cin >> firstNumber >> secondNumber;

    cout << (firstNumber > secondNumber ? firstNumber : secondNumber) << endl;

    return 0;
}

Решение с max():

#include <iostream>

using namespace std;

int main() {

    int firstNumber, secondNumber;
    cin >> firstNumber >> secondNumber;

    cout << max(firstNumber, secondNumber) << endl;

    return 0;
}
