Can I increase the size of a dynamically allocated array? < Yes / No> if yes, how?

Correct Answer: Yes, using the realloc() function as shown below: main() { int *p; p = ( int *) malloc (20) ; t = p; t = (int *) realloc ( p, 40); if ( t == NULL ) Printf (" Cannot reallocate, leaves previous allocated region unchanged "); else { if ( p ==t ) ; / * the array expanded at the same region */ else { free ( p ); / * deallocate the original array */ p = t; /* set p to newly allocated region */ } } }
