Re: function pointers

how the function poiners avoids the usage of switch cases?

Here's a typical switch statement:

switch (user_input)
{
case 0: DeleteFile(); break;
case 1: CopyFile(); break;
case 2: RenameFile(); break;
case 4: MoveFile();
}

And here's the function pointer equivalent:

void (*const funcs[4])(void) = {DeleteFile,CopyFile,Renamefile,MoveFile};

funcs[user_input];
