c语言代码解决问题

解题思路:

注意事项:

参考代码:

#include<stdio.h>

#include<string.h>

int main()

{

    char str[1001];

    gets(str);

    str[strlen(str)] = '\0';

    int i,sum=1;

    for (i = 0; i < strlen(str); i++)

    {

        if (str[i] == str[i + 1] || str[i] == str[i + 1] + 32 || str[i] == str[i + 1] - 32)

        {

            sum++;

        }

        else

        {

            printf("(%c,%d)", toupper(str[i]), sum);

            sum = 1;

        }

    }

    return 0;

}
