8.7.2.Return value as pointer

#include <stdio.h>



long *myFunction(long* pPay);          



int main(void)

{

  long your_pay = 30000L;             

  long *pold_pay = &your_pay;         

  long *pnew_pay = NULL;              



  pnew_pay = myFunction( pold_pay );

  printf("\nOld pay = $%ld", *pold_pay);

  printf("   New pay = $%ld\n", *pnew_pay);

  return 0;

}



long *myFunction(long *pPay)

{

  *pPay += 10000L;                    

  return pPay;                        

}

Old pay = $40000   New pay = $40000
