写了个Bug。。。

[sq4250]

当我键入数字时一切安好 然后就死循环了，当我键入数字以外的符号时23333 代码：

#include<stdio.h>
#include<stdlib.h>
#include<time.h>

char str[3];int m;
int main(){
    do{
    srand((unsigned)time(NULL));
    int n=rand()%1000;int i=1;
    printf("Type a number up to 1000:");
    scanf("%d",&m);
    while(m!=n)
    {
        if     (m>n) printf("Too big!\nType a number up to 1000:");
        else if(m<n) printf("Too small!\nType a number up to 1000:");
        scanf("%d",&m);
        i++;
    }
    getchar();
    printf("Congratulation!(%d times)\n",i);
    printf("NEW GAME?(y/n):");
    gets(str);
    }while (str[0]=='y');
    return 0;
}

加了一行

while(getchar()!＝'\n');

清除缓存

#include<stdio.h>
#include<stdlib.h>
#include<time.h>
char str[3];int m;

int main(){
    do{
    srand((unsigned)time(NULL));
    int n=rand()%1000;int i=1;
    printf("Type a number up to 1000:");
    scanf("%d",&m);
    while(m!=n)
    {
        if     (m>n) printf("Too big!\nType a number up to 1000:");
        else if(m<n) printf("Too small!\nType a number up to 1000:");
       while(getchar()!='\n');
        scanf("%d",&m);
        i++;
    }
    while(getchar()!='\n');
    printf("Congratulation!(%d times)\n",i);
    printf("NEW GAME?(y/n):");
    gets(str);
    }while (str[0]=='y');
    return 0;
}
