Answer 1

// Passing Two-dimensional arrays as parameters to functions.
#include <iostream> 
#include <iomanip> 
using namespace std; 
const int NUMBER_OF_ROWS = 6; 
const int NUMBER_OF_COLUMNS = 5; 
void printMatrix(int matrix[][NUMBER_OF_COLUMNS],
int NUMBER_OF_ROWS);
void sumRows(int matrix[][NUMBER_OF_COLUMNS],
int NUMBER_OF_ROWS);
void largestInRows(int matrix[][NUMBER_OF_COLUMNS],
int NUMBER_OF_ROWS);
int main() 
{ 
int board[NUMBER_OF_ROWS][NUMBER_OF_COLUMNS]
= {{17, 8, 24, 10, 28},
{9, 20, 16, 55, 90},
{25, 45, 35, 8, 78},
{5, 0, 96, 45, 38},
{76, 30, 8, 14, 28},
{9, 60, 55, 62, 10}}; 
printMatrix(board, NUMBER_OF_ROWS); 
cout << endl;

} 
void printMatrix(int matrix[][NUMBER_OF_COLUMNS],
int numOfRows)
{

}
}
void sumRows(int matrix[][NUMBER_OF_COLUMNS], int numOfRows)
{
int row, col;
int sum;


for (row = 0; row < numOfRows; row++)
{

for (col = 0; col < NUMBER_OF_COLUMNS; col++)
sum = sum + matrix[row][col];
cout << "Sum of row " << (row + 1) << " = " << sum
<< endl;
}
}
void largestInRows(int matrix[][NUMBER_OF_COLUMNS],
int numOfRows)
{
int row, col;
int largest;


for (row = 0; row < numOfRows; row++)
{
largest = matrix[row][0]; 


for (col = 1; col < NUMBER_OF_COLUMNS; col++)
if (largest < matrix[row][col])

cout << "The largest element of row " << (row + 1)
<< " = " << largest << endl;
}
}

Two-dimensional array as arguments to a method (function).

Bypassing an array to a function, it is possible to get the maximum in each row, and also find the sum and the average of all the elements in the array. Since functions are reusable, different arrays can be passed to the functions and get the average and the maximum.
