#include<stdio.h>
#include<time.h>
#include<stdlib.h>
#define MAXNO 10
#define MAXTIME 1
main()
{ int no; /* 当前已做到第几题 */
int time; /* 该题已做了多少次 */
int x,y,operator; /* 运算数和运算付*/
int answer,guess; /* 标准答案和操作者回答的数 */
int wrong; /* 当前题做错标志 */
int count=0; /* 已做对的题数 */
rand(); /* 随机数发生器初始化 */
for(no=1;no<=MAXNO;no++)
{ printf("NO %d:\n",no);
x=random(1000);
y=random(1000);
operator=random(4);
switch(operator) /* 把0~3转化成+,-,*,/运算付 */
{ case 0:printf("%d+%d=?",x,y);
answer=x+y;
break;
case 1:printf("%d-%d=?",x,y);
answer=x-y;
break;
case 2:printf("%d*%d=?",x,y);
answer=x*y;
break;
case 3:while(y==0||x%y!=0) /* 确保x/y为整数 */
{ x=random(1000);
y=random(1000);
}
printf("%d/%d=?",x,y);
answer=x/y;
}
}
for(time=1;time<=MAXTIME;time++)
{ scanf("%d",&guess);
if(guess==answer)
count++;
printf("%d %d",guess,answer);
}
count=2*count;
printf("%d",count);
}
我写的大致程序如上，现在需要解决的是如何让它在输出小于10个答案的时候也能正确的输出得分，高手来帮帮忙啊！！！！
该了下你的程序，是不是初学者
#include<stdio.h>

else

}
}
