Question

我编写了一个用于在Turbo C ++中显示GUI菜单的代码，但我不知道为什么它不会识别initgraph

这是输出消息 BGI错误：图形未初始化当我在Turbo C ++中尝试使用更简单的图形程序时，它说egavga.bgi没有找到，但它在我的turbo c ++文件夹中的bgi文件中此外，当我试图将bgi的位置放在initgraph中时它没有做任何事情

这是程序代码

#include<iostream.h>
#include<conio.h>
#include <dos.h>
#include<graphics.h>

//Menu Global Item
#define pixTOrc(x) (8*(x-1))  //convert pixel into row and col format
#define INC 5  //Increment Distance Between Menu Items
#define ROW 15 //Row Value for Menu Item
#define COL 8 //Column Value for Menu Item
#define MAXMENU 5 //Total menu items

// To display the Inventory Main menu options
typedef char option[20];
option MMenu[]= {
             "View Account",
                "Transactions",
                "New Accont",

可能的解决方案： 将所有文件从BGI文件夹复制到BIN 。检查它是否有效。

为什么initgraph在我的程序中没有得到认可？
