This post will discuss how to delete the vector’s contents and free up the memory allocated by the vector to store objects in C++. 1. Using vector::clear function We can use the vector::clear function to remove all elements from the vector. It works by calling a destructor on each ...

Destroying the Vector Any object created is in some scope. The vector is created and destroyed in the main() function scope in this section of the article. The syntax to destroy a vector is: a.~X() where ‘a’ is the name of the vector, and X is the class name of the vector. ...
Proposal a = slices.Delete(a, i, j) should zero the (j - i) elements after the length of the returned slice TL;DR zeroing the elements is error-prone, it should be taken care of by the stdlib function. Chronology 2012 Go 1.0 released. It...
thenewoperator. The following example code demonstrates such a scenario and then frees the corresponding resources before returning from themainfunction. Mind that not calling thedeleteoperator on the heap objects will result in a memory leak, leading to massive memory usage for the long-running ...

这是一个栈平衡被破坏的错误。在 vs 中单步调试可以知道是在执行 delete(pBaseA); 的时候导致的错误。奇怪的是,在崩溃之前,还输出了一个 NewB::PerfectFunctionName。光看源码,看不出什么问题了,需要查看反汇编代码了。
