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=0,j, length_character=0;

    while (str[i] != '\0')

    {

        while (str[i] != ' '&&str[i]!='\0')

        {

            length_character++;

            i++;

        }

        if (str[i] != '\0' && i != strlen(str)-1&&length_character!=0)

        {

            printf("%d,", length_character);

        }

        else if(length_character!=0)

            printf("%d", length_character);

        if (str[i] == ' ')

        {

            length_character = 0;

            i++;

        }

    }

    return 0;

}
