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[501];

    gets(str);

    str[strlen(str)] = '\0';

    int i = 0, start = 0, end = 0, j;

    while (1)

    {

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

        {

            i++;

        }

        end = i - 1;

        for (j = start; j <= (start+end)/2; j++)

        {

            char c;

            c = str[j];

            str[j] = str[end - (j - start)];

            str[end - (j - start)] = c;

        }

        if (str[i] == '\0')

            break;

        start = i + 1;

        i++;

    }

    printf("%s\n", str);

    return 0;

}
