* Always check for equal number of malloc()/free() calls.
• Use calloc() instead of malloc() + memset()
• Instead of allocation memory in a piece-meal manner, try to allocate a bigger chunk with malloc() and keep on resizing it with realloc() if needed.
• malloc() over-commits the memory i.e. it gives you an address which actually does not exist!
• malloc() grouping & reallocing with "more than you want"
