@ykily b可能大于26

#include<iostream>
#include<cstdio>
    // Added a line here.
#include <cstring>

using namespace std;

int main()
{
    int b,i=-1,k=0;
     scanf("%d",&b);
    char a[105];
    // Added a line here.
    memset(a, 0, sizeof(a));

    // Deleted a function here.

    /* 
    do
     {
        ++i;
        scanf("%c",&a[i]);
     }
     while(a[i]!='\n');
    */

    // Added two lines here.

    scanf ("%s", a);
    i = strlen(a);

    while(k!=i)
    {
        // swapped the three lines.
        if(a[k] + b>'z')
        a[k]=a[k]-'z'+'a'-1;
        a[k]+=b;
        cout<<a[k];
         ++k;
    }
    return 0;
}

顺便帮着改了点其他不规范的地方

如果 k 是 26，char 是 'z' 的话，就爆掉了
