C-string unable to display

[Drakonaut]

Hello, I was working on a question and I seemed to be unable to get this part working properly.

 else if (m == 'c')
     {
      std::cout << "Enter the number of sentences used: ";
      int e;
      std::cin >> e;
      std::cin.clear();
      std::cin.ignore(1000, '\n');
      std::cout << "You've " << e << " number of sentences required to be filled.\n";
      char * f[e];
      for (int i = 0; i < e; i++)
      {
        std::cout << "Enter your " << i << " sentence: ";
        std::cin.getline (f[i], 99);
      };
      char * g = maxn (f, e);
      std::cout << "Your longest sentence is: " << g;
     }

What I got instead was this:

Enter the number of sentences used: 4
You've 4 number of sentences required to be filled.
Enter your 0 sentence: Orange Juice

Exit code: 0 (normal program termination)

I know I can use string instead of a c-string, but the exercise I'm doing only permits c-string. Is there any way I can solve this problem? Thanks!

Edit: I tried using ignore and clear below the getline function but I still got a cut-off message from the console.

f is an array of pointers but you have forgot to initialize the pointers. You need to make them point somewhere.

Do you have any idea how to I go about solving this problem?

If I'd given the strings beforehand, the program works. But getting user inputs seem to left me stuck at this portion.

EDIT: I found out how to resolve this problem. Thanks!
