• lowestPrice function returns name and price of the product that has the lowest price among all given products.

• highestPrice function returns name and price of the product that has the highest price among all given products.

  call function price and pass a reference to lowestPrice function, and make sure you get the correct returned value. call function price and pass a reference to highestPrice function, and make sure you get the correct returned value.
