1583 - 比较字符串
输入两个字符串，比较两字符串的长度大小关系。
题目输入
输入第一行表示测试用例的个数m，接下来m行每行两个字符串A和B，字符串长度不超过50。
题目输出
输出m行。若两字符串长度相等则输出A is equal long to B；若A比B长，则输出A is longer than B；否则输出A is shorter than B。
输入/输出样例
题目输入
2 abc xy bbb ccc
题目输出
abc is longer than xy bbb is equal long to ccc

C++解答
#include <cstdio> #include <cstring> int main() { //freopen("test.in", "r", stdin); //freopen("test.out", "w", stdout); int t; char s1[100], s2[100]; scanf("%d", &t); while (t--) { scanf("%s %s", s1, s2); int k = strlen(s1) - strlen(s2); if (k > 0) printf("%s is longer than %s\n", s1, s2); else printf("%s %s %s\n", s1, 0 == k ? "is equal long to" : "is shorter than", s2); } return 0; }
