用c++实现输入三个正整数，按从大到小排序输出

#include <stdio.h>

int main() {
    int a, b, c, temp;
    printf("请输入三个正整数：\n");
    scanf("%d%d%d", &a, &b, &c);
    if (a < b) {
        temp = a;
        a = b;
        b = temp;
    }
    if (a < c) {
        temp = a;
        a = c;
        c = temp;
    }
    if (b < c) {
        temp = b;
        b = c;
        c = temp;
    }
    printf("从大到小排序后的结果为：%d %d %d\n", a, b, c);
    return 0;
}
