Question

i am getting a REALLY annoying error. i literally looked everywhere for it! i even went back and changed all of my

if (case)
    // 纽约总部-do

纽约总部

if (case)
{
    // 纽约总部-do
}

i 不要提出像这样的许多问题,但我确实感到沮丧。几乎肯定的是,我看不到一点。

这里的错误是:

entity.cpp: In member function ‘virtual void Entity::clean()’:
entity.cpp:148: error: a function-definition is not allowed here before ‘{’ 纽约总部ken
entity.cpp:394: error: expected ‘}’ at end of input

这里是我的班级法典:

编辑:我不知道为什么一些登革热会爆发。现在就确定。

Answer 1

  image_buffer_ = NULL; // just set it to null if it doesn t :
}

在一线尾插入斜坡,使其与以下线相呼应,这实际上是对你职能的关闭表示意见。

Answer 2

观察这一路线:

  image_buffer_ = NULL; // just set it to null if it doesn t :

这从多线评论开始,评论如下:

你的汇编者应当就此向各位发出警告。

删除<条码>,然后,您可转而处理其他警告和错误!

Answer 3

    image_buffer_ = NULL; // just set it to null if it doesn t :
}

这里的指针:你认为越狱的性质是什么?

是的,这一权利越了越权,实际上就将最后的宽限期带入了评注。

因此,你再次找不到一个结局。

或许你们应该把你们的情绪从法典中抹去。

Answer 4

如果你使用一部汽车登机码编辑(如果你不这样做,为什么不?),就会立即向你们展示不平衡的镜子。 (当然假定这足以承认......为多线评论:-)
