Q:

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

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 */


             }


      }


}
