在抛出 'std::bad_alloc' 的实例后调用终止 what(): std::bad_alloc 在推回向量后

Question

I'm facing a problem here, I've declared a pointer to a vector. After element insertion, it shows me this error

terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc

Here is my code:

vector<string>* strategies;

cout << "Name of the player 1 : ";
cin >> name;

strategies->push_back(name);

Answer 1

I hope you'd have declared string name;

second, you are creating a pointer but not doing new() of some vector to which *strategies pointer really points. if all your purpose is to insert an element in vector then you really don't need a pointer rather you need object of vector<string> code
