In a place If you want a variables to be allocated and initialized....

For example, If you want a buffer you will just use malloc.
But if you want a buffer initialized and all of its values 0 then you have to use malloc followed by memset, To avoid just you can use a calloc..

Talking about the program memory If you want to reduce the sizze then use less functions that means, In a program if you already used malloc then Its better using malloc memset, or use calloc in both places but using malloc and calloc in two places will increase the code size because it uses two inbuilt functions.......
