思路：

用strlen()获取长度。

解答：

#include <cstdio>
#include <cstring>
#include <iostream>
#include <cstdlib>
using namespace std;

int main() {
    int sample_num;
    while(scanf("%d", &sample_num) != EOF) {
        while(sample_num--) {
            char str1[100];
            char str2[100];
            
            scanf("%s %s", str1, str2);

            int str1_len = strlen(str1);
            int str2_len = strlen(str2);

            if(str1_len == str2_len) 
                cout << str1 << " is equal long to " << str2 << endl;
            else if (str1_len < str2_len)
                cout << str1 << " is shorter than " << str2 << endl;
            else if (str1_len > str2_len)
                cout << str1 << " is longer than " << str2 << endl;
        }
    }

    return 0;
}

笔记：

scanf获取字符串时遇到空格就结束
