二、实现细节

gets函数获取带空格的一行输入

 

三、实现代码

#include <iostream>
#include <string.h>
#include <stdio.h>

using namespace std;

int main()
{
    char c[100];
    char tmp;
    int i;
    while(gets(c)){
        if(strcmp(c,"ENDOFINPUT")==0) break;
        else if(strcmp(c,"START")==0);
        else if(strcmp(c,"END")==0);
        else{
            i=0;
            while(c[i]!='\0'){
                if(c[i]>=65&&c[i]<=90){
                    tmp=c[i]-5;
                    if(tmp<65) tmp=tmp-65+90+1;
                    cout<<tmp;
                }
                else
                    cout<<c[i];
                i++;
            }
            cout<<endl;
        }
    }

    return 0;
}
