C语言 电报加密&

解题思路:

注意事项:

参考代码:

#include<stdio.h>

#include<string.h>

#define Long 80//允许输入字符串长度

int main()

{

            void telegraph_decrypt(char* telegraph, int n);

            char telegraph[Long];

            gets_s(telegraph, Long);

            telegraph_decrypt(telegraph, strlen(telegraph));

            printf("%s", telegraph);

            return 0;

}

void telegraph_decrypt(char * telegraph,int n)

{

        int i;

        for (i=0; i < n; i++)

        {

            if (*(telegraph + i) >= 'a' && *(telegraph + i) <= 'y')*(telegraph + i)=*(telegraph + i) + 1;

            else if (*(telegraph + i) == 'z')*(telegraph + i) = *(telegraph + i) - 25;

        }

}
