Question

Could someone please help me with this assignment?

Look at the following table containing prices of certain items:

12.78 23.78 45.67 12.67

7.83 4.89 5.99 56.84

13.67 34.84 16.71 50.89

These numbers can be read into a two-dimensional array.

Exercise 1: Fill in the code to complete both functions gePrices and printPrices, then run the

program with the following data:

Please input the number of rows from 1 to 10

2

Please input the number of columns from 1 to 10

3

Please input the price of an item with 2 decimal places

1.45

Please input the price of an item with 2 decimal places

2.56

Please input the price of an item with 2 decimal places

12.98

Please input the price of an item with 2 decimal places

37.86

Please input the price of an item with 2 decimal places

102.34

Please input the price of an item with 2 decimal places

67.89

1.45 2.56 12.98

37.86 102.34 67.89

Exercise 2: Why does getPrices have the parameters numOfRows and numOfCols passed by

reference whereas printPrices has those parameters passed by value?

Exercise 3: 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;

}

NOTE: This is a value returning function. Be sure to include its prototype

in the global section.

Exercise 4: Create another value returning function that finds the lowest price in the array and

have the program print that value.

Exercise 5: After completing all the exercises above, run the program again with the values from

Exercise 1 and record your results.

// This program will read in prices and store them into a two-dimensional array

// It will print those prices in a table form.

#include <iostream>

#include <iomanip>

using namespace std;

const MAXROWS = 10;

const MAXCOLS = 10;

typedef floatPriceType[MAXROWS][MAXCOLS]; // creates a new data type

// of a 2D array of floats

void getPrices(PriceType, int&, int&); // gets the prices into the array

void printPrices(PriceType, int, int); // prints data as a table

int main()

{

int rowsUsed; // holds the number of rows used

int colsUsed; // holds the number of columns used

PriceType priceTable; // a 2D array holding the prices

getPrices(priceTable, rowsUsed, colsUsed); // calls getPrices to fill the array

printPrices(priceTable, rowsUsed, colsUsed); // calls printPrices to display array

return 0;

}

}
