The std::sort function is commonly used to sort a vector in C++. By default, it sorts the elements in ascending order, and it modifies the original vector. Example Here's the C++ code to sort a vector using std::sort. We call std::sort(v.begin(), v.end()) to sort the vector ...
std::vector in GCC 13 GCC 13和GCC 4.9的实现没有太大区别,只是将Implementation类的数据部分单独抽象,并改成了多继承。 目前最新版的Container都是在GCC 4.9上做小改动,大部分Container都是将data成员单独抽象,并拥有Container_data->[Container_data_base]这样的继承关系,然后Composite一个Container_data_base对象...

The behavior of a C ++ program is undefined if it adds declarations or definitions to namespace std or to a namespace within namespace std unless otherwise specified. - IS g++ seems to accept a program adding declarations for allocator<> and vector<> in the namespace std; clang++ does ...
Your do-while loop really adds nothing to the code- just executes once. So you might want to check that in case it's not what you intended. Next specifically where inSCConfig::GetAllLangugesName(std::vector<std::wstring> &outLangNames)does it cause a crash? and after how many iterati...
