1 // Program Chart2 manipulates a two-dimensional array // variable. #include<iostream> #include<fstream> usingnamespace std; constint ROW_MAX = 8; constint COL_MAX = 10; typedefint ItemType; typedefitemtype ChartType[ROW_MAX][COL_MAX]; voidgetchart(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; } //*************************************************** voidgetchart(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

2 // 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. data >> chart[row][col] ; //**************************************************** voidprintchart(ofstream& data, const ChartType chart, int rowsused, int colsused) // Pre: The chart contains valid data. // Post: Values in the chart have been sent to a file by row, // one row per line. { for (int row = 0; row < rowsused; row++) { for (int col = 0; col < colsused; col++) { cout << chart[row][col] <<" "; } } } cout << endl; Part 1:Add a function that sums the values in a column of array variable chart. Pass the column you want to sum as a parameter. Call your function to print the sum of each column appropriately labeled. Sum of Column [1] [2] [3] [4] [5]

3 Part 2:Add a function that prints the largest value in array variable chart. Rerun the program. Add a function that prints the lowest value in array variable chart. Rerun the program.
