How do I use type aliases with using in C++?

In C++, type aliases can be created using the `using` keyword. This feature allows for a more readable and convenient definition of types, especially when dealing with complex type declarations. Here's how you can use type aliases with `using`:


    // Define a type alias for an integer pointer
    using IntPtr = int*;

    // Define a type alias for a function pointer
    using FuncPtr = void(*)(int);

    // Using the type alias
    IntPtr ptr = nullptr;
    FuncPtr func = nullptr;
