字符数组遍历解决

解题思路:

注意事项:

参考代码:

#include<stdio.h>

#include<string.h>

int main()

{  

    char str[100] = { 0 };//初始化字符数组

    int n;//输入n个字符串

    scanf("%d", &n);

    for (int i = 0; i < n; i++) {

        scanf("%s", str);//读入字符串

        int str_len = strlen(str);

        int cnt = 1;        //计数

        for (int j = 0; j < str_len; j++) {         //遍历字符

            if (str[j] == str[j + 1]) {//前后相同就计数

                cnt++;

            }

            if (str[j] != str[j + 1]) {     //只有当出现前一个与后一个不同时才会开始打印结果

                if (cnt > 1) { printf("%d", cnt); }

                printf("%c", str[j]);

                cnt = 1;        //初始化

            }

        }

        printf("\n");

    }

    return 0;
