C程序结果问题

#include<stdio.h>
#include<time.h>
#include<stdlib.h>
main()
{
int magic;
int guess;
char vae;
srand(time(NULL));


do{
magic=rand()%100;
printf("please guess a magic number:");
scanf("%d",&guess);
if(guess>magic){
printf("wrong!too high!\n");
}
else if(guess<magic){printf("wrong!too low!\n");}
else {printf("congrandunations!\n");
printf("are you continue!y|n\n");
scanf(" %c",&vae);
}
}while(1);
}
结果出问题，帮帮忙。

#include<stdio.h>
#include<time.h>
#include<stdlib.h>
main()
{
int magic;
int guess;
char vae;
srand(time(NULL));


do{
magic=rand()%100;
printf("please guess a magic number:");
scanf("%d",&guess);
if(guess>magic){
printf("wrong!too high!\n");
}
else if(guess<magic){printf("wrong!too low!\n");}
else {printf("congrandunations!\n");
printf("are you continue!y|n\n");
scanf(" %c",&vae);

if(!(vae=='y' || vae =='Y'))

break;
}
}while(1);
}

出了什么问题呢？？
