Exercise 2: Add a function that prints the largest value in array variable chart. Rerun

the program.

Largest value is __________.

Given file in .dat file:

4 5 3 1 4 1 5 2 3 6 7 1 7 8 8 8 8 9 8 7 6 5

// Program Chart2 manipulates a two-dimensional array // variable.

#include #include using namespace std;

const int ROW_MAX = 8; const int COL_MAX = 10;

typedef int ItemType;

typedef ItemType ChartType[ROW_MAX][COL_MAX];

void GetChart(ifstream&, ChartType, int&, int&); // Reads values and stores them in the chart.

void PrintChart(ofstream&, const ChartType, int, int); // Writes values in the chart to a file.

int main () { ChartType chart; int rowsUsed; int colsUsed; ifstream dataIn; ofstream dataOut;

dataIn.open("chart2.dat"); dataOut.open("chart2.out"); GetChart(dataIn, chart, rowsUsed, colsUsed); PrintChart(dataOut, chart, rowsUsed, colsUsed); return 0; }

//***************************************************

void GetChart(ifstream& data, ChartType chart, int& rowsUsed, int& colsUsed) // Pre: rowsUsed and colsUsed are on the first line of // file data; values are one row per line // beginning with the second line. // Post: Values have been read and stored in the chart.

{ ItemType item; data >> rowsUsed >> colsUsed;

for (int row = 0; row < rowsUsed; row++) for (int col = 0; col < colsUsed; col++) // FILL IN Code to read and store the next value. }
