OpenGL项目编译无报错无法弹出显示窗口，报错0xC0000005如何解决

错误原因 #

• 1. main函数参数类型错误：glutInit要求传入的第一个参数是int*类型，你将argc定义为引用类型int&，传参时发生内存访问越界，直接触发0xC0000005错误码（内存访问违规）。
• 2. Display回调内嵌套百万次循环：GLUT是事件驱动框架，Display函数仅负责单次画面绘制，内部的死循环会完全阻塞GLUT的事件处理逻辑，导致窗口无法正常创建、响应渲染请求。
• 3. Reshape回调内递归触发重设窗口大小：glutReshapeWindow会主动触发Reshape回调，你在Reshape内部调用该函数会导致无限递归，最终栈溢出触发崩溃。
