Question

请问这个C++程序哪里出错了，为什么每次编译链接的时候能行，却运行不了。

#include<stdio.h>
void main()
{
int score;
char grade;
printf("please input a student's score:");
scanf("%d",score);
while(score>100||score<0)
{
printf("\ninput error,try again!");
scanf("%d",score);
}
switch(score/10)
{
case 10:
case 9: grade='A';break;
case 8: grade='B';break;
case 7: grade='C';break;
case 6: grade='D';break;
default: grade='E';break;
}
printf("score=%5.1d,grade=%c.\n",score,grade);
}

Answer 1

scanf("%d",score);改成scanf("%d",&score); 下面还有个 改了

Answer 2

int score;
char grade;
printf("please input a student's score:");
//score前面加&号
scanf("%d",&score);

Answer 3

输入语句错了，输入语句传进入的应该是变量的地址scanf("%d",&score);

Answer 4

这段编码中的scanf语句错误，正确的是
scanf("%d,&score")
你再试一下。
