Question

请问，下面程序是哪里出问题了呢？输入数据后，一按回车就出问题。 感激不尽...

#include<stdio.h>
struct goods
{
long num;
char name[20];
float price;
int number;
float sumprice;
}good[10];
main()
{
int i;
printf("Please input the information of the goods:\n");
for(i=0;i<10;i++)
{
printf("The %d:\n",i+1);
scanf("%ld%s%f%d",&good[i].num,good[i].name,good[i].price,&good[i].number);
good[i].sumprice=good[i].price*good[i].number;
}
printf("Num\tName\tPrice\tNumber\tSumprice\n");
for(i=0;i<10;i++)
{
printf("%ld\t%s\t%.1f\t%d\t.1f\n",good[i].num,good[i].name,good[i].price,good[i].number,good[i].sumprice);
}
}

#include<stdio.h>
struct goods
{
long num;
char name[20];
float price;
int number;
float sumprice;
}good[10];
main()
{
int i;
printf("Please input the information of the goods:\n");
for(i=0;i<10;i++)
{
printf("The %d:\n",i+1);
scanf("%ld%s%f%d",&good[i].num,&good[i].name,&good[i].price,&good[i].number);/*这边漏掉了 取地址运算符 & */
good[i].sumprice=good[i].price*good[i].number;
}
printf("Num\tName\tPrice\tNumber\tSumprice\n");
for(i=0;i<10;i++)
{
printf("%ld\t%s\t%.1f\t%d\t.1f\n",good[i].num,good[i].name,good[i].price,good[i].number,good[i].sumprice);
}
}

Answer 2

亲，scanf("%ld%s%f%d",&good[i].num,good[i].name,good[i].price,&good[i].number);里面
对于price忘了加&了吧。
改为scanf("%ld%s%f%d",&good[i].num,good[i].name,&good[i].price,&good[i].number);

{
printf("The %d:\n",i+1);
scanf("%ld%s%f%d",&good[i].num,&good[i].name,&good[i].price,&good[i].number);
good[i].sumprice=good[i].price*good[i].number;
}
printf("Num\tName\tPrice\tNumber\tSumprice\n");
for(i=0;i<10;i++)
{
printf("%ld\t%s\t%.1f\t%d\t%.1f\n",good[i].num,good[i].name,good[i].price,good[i].number,good[i].sumprice);
