求大佬帮忙看看，运行没毛病

#define _CRT_SECURE_NO_WARNINGS 1
#include<stdio.h>
int main() {
    int n;
    char ch ;
    scanf("%d", &n);
    getchar();
    while ((ch = getchar()) != '\n') {
        putchar( (ch - 97 + n)%26+97);
    }
}

scanf是为了把换行符清空，避免干扰下面的getchar

我看了一下第一个样例也是没问题的

换行符问题

#define _CRT_SECURE_NO_WARNINGS 1
#include<stdio.h>
int main() {
    int n;
    char ch ;
    scanf("%d", &n);
    getchar();  getchar();
    while ((ch = getchar()) != EOF) {
        putchar( (ch - 97 + n)%26+97);
    }
}

@编码落寞 第二个getchar有什么作用

by 编码落寞 @ 2023-07-13 16:25:40

@TiAm0

windows中要回车符+换行符("\r\n")才会回车+换行

网上找的
