To implement the address Book dynamically, you need to use these functions such as malloc and realloc, first let's introduce these functions. (1) void *malloc (unsigned int size);Size is the number of bytes that need to be allocated.(2) void *calloc (unsigned int num_elements,unsigned int elements_size);Num_elements is the number of elements allocated, Elements_size is the number of bytes per element.(3) void *realloc (void *p,unsigned int new_size);
