The function malloc () of header file <stdlib.h> allocates memory of size (in bytes) expressed as its argument. The return value of malloc () is a void pointer to the first byte of the allocated block of memory. However, if the process of allocation of memory fails due to lack of sufficient memory, or due to some other reason, it returns NULL pointer. The argument of malloc () is the unsigned integer or an expression which evaluates to an unsigned integer. Any program using this function should also have statements which check the return value of the function so that if the memory is not available one can gracefully exit from the program.
