8.5.6.Cube a variable using call-by-reference with a pointer argument
#include <stdio.h>

void cubeByReferenceint *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 cubeByReferenceint *nPtr )
{
   *nPtr = *nPtr * *nPtr * *nPtr;  /* cube *nPtr */
}
The original value of number is 5
The new value of number is 125
