问题描述
我知道有一个函数可以允许我调整内存块的大小(它与一个自由功能配对)。然而,我试图做同样的一个c ++类与一些成员指针分配内存使用新而不是 realloc 。在c ++中是否有与 realloc 相同的关键字,这将允许我在使用new / delete而不是malloc或realloc和free配对内存时实现相同的目标?
I'm aware that there is a realloc function that would allow me to resize the memory block (and it's paired with a free function). However, I'm trying to do the same to a c++ class with some member pointers allocated memory using new instead of realloc. Is there an equivalent keyword to realloc in c++ that would allow me to achieve the same goal when the memory is paired using new/delete rather than malloc or realloc and free?
提前感谢。
推荐答案
不,没有。坦率地说,如果你使用新的或新的[]。你的C ++代码可能没有很好的设计。看看使用 std :: vector 而不是新的[],并使用值而不是新的。
No, there isn't. And frankly, if you are using new or new[]. your C++ code is probably not well designed. Look at using std::vector instead of new[], and at using values instead of new.
