Initializing an array of characters with a string variable

I understand that char a[] = "Hello World"; works, but I was wondering if there was a way that you could have the array of characters initialized by a string inputed at run-time. For example: 

string word;

cout << "Enter a word ";

cin >> word;

char a[] = word;

I know that clang++ does not accept this because it says, "array initializer must be an initializer list or string literal".

Is there a work around for this without using pointers?

Solution

  • Use c_str.

    And something like this to copy to array:

    strcpy(a, word.c_str());
