题目描述
代码：
#include<stdio.h>int main(){char str[55];int i;scanf("%s", &str);for (i = 0; str[i]; i++){if (str[i] >= 'a' && str[i] <= 'z'){str[i] = str[i] == 'z' ? 'a':str[i] + 1;} else if (str[i] >= 'A' && str[i] <= 'Z'){str[i] = str[i] == 'Z' ? 'A':str[i]+1;} else {continue;}}printf("%s", str);return 0;}知识点：（1）字符数组（2）三目运算
str[i] = str[i] == 'z' ? 'a':str[i] + 1;（3）循环语句
