我的解答思路和尝试过的方法

#define _CRT_SECURE_NO_WARNINGS
#include<stdio.h>
int main()
{
    char sta[10];
    char stb[10];
    char stc[10];
    scanf("%s %s %s", &sta, &stb, &stc);
    char* a = &sta;
    char* b = &stb;
    char* c = &stc;
    if (strcmp(a, b) == 1)
    {
        char* temp;
        temp = a;
        a = b;
        b = temp;
    }
    if (strcmp(a, c) == 1)
    {
        char* temp;
        temp = a;
        a = c;
        c = temp;
    }
    if (strcmp(b, c) == 1)
    {
        char* temp;
        temp = b;
        b = c;
        c = temp;
    }
    printf("%s\n%s\n%s", a, b, c);
    return 0;
}
