#include "stdafx.h"


int _tmain(int argc, _TCHAR* argv[])
{
    int repeat,ri;
    char ch;
    scanf("%d",&repeat);
    for(ri=1;ri<=repeat;ri++)
    {
        ch=getchar();
        if (ch>='a'&&ch<='z') ch=ch-32;
        else if (ch>='A'&&ch<='Z') ch=ch+32;
        else ch=ch;
        putchar(ch);
    }
    return 0;
}

想知道我这个怎么改，他没法正常的循环

{ri--;continue;
        }
这句话是什么意思？
