SIMPLE Dynamic char array

[rkstengel]

I am trying to get user input and create an array with the length of char entered.

Instead of:

const int MAX = 3000;
char msg[MAX];

cout << "Enter a sentence";
	
cin.clear();
cin.width(MAX);
cin.getline(msg, MAX);

Without using strings, I would like to do this: Where ? will be the number of characters entered?

const int MAX = ?;
char msg[?];

cout << "Enter a sentence";

...

[Moschops]

int size;
cout << "How big?";
cin >> size;

char* pArray = new char[size];

A better opiton would be to use a proper C++ container such as vector that handles its own size.

@Moschops I think the purpose is not to ask the user how many characters they intend to enter.
@OP Why are you against std::string?
