C style arrays question

[Raigne]

This is how to make a C style array of pointers right? Wondering cause I want to make an array that can be resized. Although I don't want to use STL. don't ask I'm weird.

    int** T = new int*[1];
    T[0] = new int(100);
    std::cout << *T[0] << std::endl;
    delete T[0];
    delete [] T;

Question is. Am I doing this right to avoid memory leaks? Wanting to know before I put it in a class, and stuff.
