在C语言中，错误地尝试使用`unsigned char [10]`赋值给指针`pImage`会导致'expected expression before 'unsigned''的报错。正确的做法是在C++中使用`new`关键字，如`pImage = new unsigned char[100];`。但在C语言中，应该使用数组声明和初始化的方式，如`unsigned char pImage[100];`。

在c++中可以这么定义：

unsigned char *pImage；
pImage = new unsigned char[100];

C应该怎么写，我按照以下方式，报错
unsigned char *pImage;
pImage = unsigned char[10];

错误： expected expression before ‘unsigned’

nsigned char *pImage；
pImage = new unsigned char[100];

C应该怎么写，我按照以下方式，报错
unsigned char *pImage;
pImage = unsigned char[10];
错误： expected expression before ‘unsigned’
