IMPLEMENT:

The following code is a function that returns the highest price in the array. After studying it very carefully, place the function in the above program and have the program print out the highest value. float findHighestPrice(PriceType table, int numOfRows, int numOfCols) // This function returns the highest price in the array { float highestPrice; highestPrice = table[0][0]; // make first element the highest price for (int row = 0; row < numOfRows; row++) for (int col = 0; col < numOfCols; col++) if ( highestPrice < table[row][col] ) highestPrice = table[row][col]; return highestPrice; }

IMPLEMENT:

Create another value returning function that finds the lowest price in the array and have the program print that value.
