Knowledge and discipline. If you're aware of how memory leaks can come about in your project and apply a disciplined approach to avoid them, that's all you need.
>Are there any good tutorials on how can we make our code Memory Leak free ??/
Probably, but I don't know of any off hand.
A lot depends on the program you are writing. Two hints:
1. Using c++ std container classes instead of C-style dynamically allocated objects is the first place to start -- assuming your compiler supports those container classes, not all c++ compilers do.
2. If you are writing Microsoft Windows programs you have to be careful about the system-wide resources that your program allocates, make sure the program frees/releases the resources before terminating.
