Question

Write a program that creates a two-dimensional array initialized with test data. Use any data type you wish. The program should have the following functions: This function should accept a two-dimensional array as its argument and return the total of all the values in the array. This function should accept a two-dimensional array as its a and return the average of all the values in the array. This function should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should subscript of a row in the array. The function should return the total of the values in the specified row. This function should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should subscript of a column in the array. The function should return the total of the values in the specified column. This function should accept a two-dimensional array as its first argument and an integer as its s

#include <iostream>

using namespace std;

const int row=3,col=3;
int getTotal(int array[][col])
{
   int total=0;
   for(int i=0;i<row;i++)
   {
       for(int j=0;j<col;j++)
       {
           total+=array[i][j];
       }
   }
   return total;
}

double getAverage(int array[][col])
{
   int total=0;
   for(int i=0;i<row;i++)
   {
       for(int j=0;j<col;j++)
       {
           total+=array[i][j];
       }
   }
   return (double)total / (row*col);
}

int getRowTotal(int array[][col], int row)
{
   row=row-1;
   int total=0;
   for(int j=0;j<col;j++)
   {
       total+=array[row][j];
   }
   return total;
}

int getColTotal(int array[][col], int col)
{
   col=col-1;
   int total=0;
   for(int j=0;j<row;j++)
   {
       total+=array[j][col];
   }
   return total;
}

int getHighestInRow(int array[][col], int row)
{
   row=row-1;
   int high=array[row][0];
  
   for(int j=1;j<col;j++)
   {
       if(array[row][j]>high)
       {
           high=array[row][j];
       }
   }
   return high;
}

int getLowestInRow(int array[][col], int row)
{
   row=row-1;
   int low=array[row][0];
  
   for(int j=1;j<col;j++)
   {
       if(array[row][j]<low)
       {
           low=array[row][j];
       }
   }
   return low;
}
int main()
{
  
   int array[][col]={{2,4,5},{7,1,9},{5,2,3}};
   int total=getTotal(array);
   cout<<endl<<"Total: "<<total;
   double avg=getAverage(array);
   cout<<endl<<"Average: "<<avg;
   cout<<endl<<"Total of elements in 2nd row: "<<getRowTotal(array,2); //specify 1,2,3
   cout<<endl<<"Total of elements in 1st column: "<<getColTotal(array,1); //specify 1,2,3
   cout<<endl<<"Highest element in 3rd row: "<<getHighestInRow(array,3); //specify 1,2,3
   cout<<endl<<"Lowest element in 2rd row: "<<getHighestInRow(array,2); //specify 1,2,3
   return 0;
}
