    Question Question Difference between realloc() and free()?
    Answer Answer The free subroutine frees a block of memory previously allocated by the malloc subroutine.Undefined results occur if the Pointer parameter is not a valid pointer. If the Pointer parameter is a null value, no action will occur. The realloc subroutine changes the size of the block of memory
    pointed to by the Pointer parameter to the number of bytes specified by the Size parameter and returns a new pointer to the block. The pointer specified by the Pointer parameter must have been created with the malloc, calloc, or realloc subroutines and not been deallocated with the free or
    realloc subroutines. Undefined results occur if the Pointer parameter is not a valid pointer.
