用c++.写两个函数，分别求两个整数的最大公约数和最小公倍数，用主函数调用两个函 数，并输出结果，两个整数由键盘输入

#include <stdio.h>

int gcd(int num1, int num2);
int lcm(int num1, int num2);

int main() {
    int num1, num2;
    printf("请输入两个整数：");
    scanf("%d %d", &num1, &num2);
    printf("%d和%d的最大公约数为：%d\n", num1, num2, gcd(num1, num2));
    printf("%d和%d的最小公倍数为：%d\n", num1, num2, lcm(num1, num2));
    return 0;
}

int gcd(int num1, int num2) {
    int temp;
    while (num2 != 0) {
        temp = num1 % num2;
        num1 = num2;
        num2 = temp;
    }
    return num1;
}

int lcm(int num1, int num2) {
    int gcd_num = gcd(num1, num2);
    return num1 * num2 / gcd_num;
}
