怎么改啊

Answer 1

#include<stdio.h>
void main()
{
char *commodity[5]={"television","refrigerator","washing machine","water heater","microwave oven"};//有错
int number[5]={5,8,10,3,6};
int unit_price[5]={5000,2200,1100,860,800};
long sale[5];
for(int i=0;i<5;i++)//有错
{
sale[i]=number[i]*unit_price[i];
}
printf("commodity\t number unit \t price\t sale\n");
for(int i=0;i<5;i++)//有错
{
printf("%s,%10d,%10d,%10ld\n",*(commodity+i),number[i],unit_price[i],sale[i]);//有错
}
}
