在我插入数学部分之前,我完成的程序运行良好。完成数学部分后,我构建了代码,没有出现错误。但是,当我尝试调试我的程序时,我得到了这个提示:“Reciept.exe 中 0x4f7ccb1a (msvcr100d.dll) 处的未处理异常:0xC0000005:访问冲突写入位置 0x4e65ab48。”
我一开始以为是数学问题,但后来我删除了它并再次运行程序,而应该像以前那样出现的结果却没有。同样的提示出现了。
你能告诉我发生了什么事吗?
这是我的代码:
#include <iostream>
#include <string>
#include <iomanip>
using namespace std;
struct menuItemType
{
string menuItem;
double menuPrice;
double sum;
double amountTotal;
double tax;
};
void getData(menuItemType menuList[8]);
void printCheck(menuItemType menuList[8]);
void showMenu(menuItemType menuList[8]);
int main()
{
menuItemType menuList[8];
getData(menuList);
showMenu(menuList);
printCheck(menuList);
system ("pause");
return 0;
}
void getData(menuItemType menuList[8])
{
menuList[1].menuItem = "Plain Egg";
menuList[1].menuPrice = 1.45;
menuList[2].menuItem = "Bacon and Egg";
menuList[2].menuPrice = 2.45;
