8. 5. 6. Cube a variable using call-by-reference with a pointer argument


#include <stdio.h>



void cubeByReference( int *nPtr );



int main()

{

   int number = 5;



   printf( "The original value of number is %d", number );

 

   cubeByReference( &number );



   printf( "\nThe new value of number is %d\n", number );



   return 0;



}



void cubeByReference( int *nPtr )

{

   *nPtr = *nPtr * *nPtr * *nPtr;  /* cube *nPtr */

}

The original value of number is 5
The new value of number is 125
