Factorial-c++我想以不同的方式打印

#include <iostream>

int factorial(int n) {
    int result = 1;
    for (int i = 1; i <= n; ++i) {
        result *= i;
    }
    return result;
}

int main() {
    int n = 5; // 假设要计算5的阶乘
    int result = factorial(n);
    std::cout << "Factorial of " << n << " is: " << result << std::endl;
    return 0;
}

#include <iostream>

int factorial(int n) {
    if (n == 0) {
        return 1;
    }
    return n * factorial(n - 1);
}

int main() {
    int n = 5; // 假设要计算5的阶乘
    int result = factorial(n);
    std::cout << "Factorial of " << n << " is: " << result << std::endl;
    return 0;
}
