The malloc() is used to assign the single block of memory at run time and the calloc() is used to assign the multiple blocks of memory at runtime.

malloc() - allocating a block of memory dynamically and sets all the bits to zero.


ptr = (cast-type*)malloc(byte_size);

calloc() - allocating multiple block of memory dynamically.


ptr=(cast-type*)calloc(n, ele_size);
n-->no of blocks

malloc will return an uninitialized chunk of memory for you to use.
calloc ( clear alloc ) will attempt to initialize that chunk of memory to all bits zero.
