问题描述

这可能吗？很抱歉，如果这个问题与此无关。


实际上，我正在尝试将无符号字符*转换为int

您是否尝试转换指针的值，或指针指向的指针是什么？


无论如何，reinterpret_cast是你想要什么。

reinterpret_cast< int>（Foo）;

无论哪种方式，reinterpret_cast都是你想要的。

reinterpret_cast< int>（Foo）;

reinterpret_cast不需要它是一个未签名的char -int

转换OP试图做的，两者都是整数类型所以正常的

作业应该这样做吧？

我认为reinpterpret_cast确实*不*与constness一起工作

也许static_cast和const_cast一起工作

Is this possible? Sorry if this question isn''t relevant here.

actually, I''m really trying to convert a unsigned char * to an int

Are you trying to convert the value of the pointer, or where the pointer is
pointing to?

Either way, reinterpret_cast is what you want.
reinterpret_cast<int>( Foo );

reinterpret_cast should not be needed it it''s a unsigned char -int
conversion the OP is trying to do, both are integer types so a normal
assignment should do, right?

I think reinpterpret_cast does *NOT* work with constness
maybe static_cast and const_cast together will work
