题目大意：按要求输出＋—＊？

解题思路：按要求读字符串即可

#include <stdio.h>#include <iostream>#include <string.h>using namespace std;int main() {    int n;    cin >> n;    getchar();    while(n--) {        char a[1000];        gets(a);        if(!strcmp(a, "1") || !strcmp(a, "4") || !strcmp(a, "78"))            printf("+\n");        else if(a[strlen(a)-2] == '3' && a[strlen(a)-1] == '5')            printf("-\n");        else if(a[0] == '9' && a[strlen(a)-1] == '4')            printf("*\n");        else if(a[0] == '1' && a[1] == '9' && a[2] == '0')            printf("?\n");    }    return 0;}
