用C++实现对 3 个变量按由小到大顺序排序用不带默认参数的函数实现的代码

#include <stdio.h>

void sort(int a, int b, int c);

int main() {
    int x = 3, y = 2, z = 1;
    sort(x, y, z);
    printf("%d %d %d\n", x, y, z);
    return 0;
}

void sort(int a, int b, int c) {
    if (a > b) {
        int temp = a;
        a = b;
        b = temp;
    }
    if (a > c) {
        int temp = a;
        a = c;
        c = temp;
    }
    if (b > c) {
        int temp = b;
        b = c;
        c = temp;
    }
}
