Write a program that declares a two-dimensional array named myFancyArray of the type double. Initialize the array to the following values: 23 14.12 17 85.99 6.06 13 1100 0 36.36 90.09 3.145 5.4 1. Create a function that will return the sum of all elements in the array. Call this function from main and print out the result. 2. Create a function that will use a nested loop to display all the elements in the array to the screen. Call this function from main.

This solution is provided in C++

#include <iostream>

using namespace std;

double sumFancyArray(double myarr[][6]){

   double sum = 0.0;

   for(int i = 0;i<2;i++)    {

       for(int j = 0;j<6;j++){

       sum+=myarr[i][j];    

       }}    

   return sum;

}

void printFancyArray(double myarr[][6]){

   for(int i = 0;i<2;i++)    {

       for(int j = 0;j<6;j++){

       cout<<myarr[i][j]<<" ";    

       }

   }

}

int main(){

   double myFancyArray[2][6] = {23, 14.12, 17,85.99, 6.06, 13, 1100, 0, 36.36, 90.09, 3.145, 5.4};

   cout<<sumFancyArray(myFancyArray)<<endl;

   printFancyArray(myFancyArray);

   return 0;

}

Explanation:

This function returns the sum of the array elements

double sumFancyArray(double myarr[][6]){

This initializes sum to 0

   double sum = 0.0;

This iterates through the row of the array

   for(int i = 0;i<2;i++)    {

This iterates through the column

       for(int j = 0;j<6;j++){

This adds each element

       sum+=myarr[i][j];    

       }}    

This returns the sum

   return sum;

}

This method prints array elements

void printFancyArray(double myarr[][6]){

This iterates through the row of the array

   for(int i = 0;i<2;i++)    {

This iterates through the column

       for(int j = 0;j<6;j++){

This prints each array element

       cout<<myarr[i][j]<<" ";    

       }

   }

}

The main starts here

int main(){

This declares and initializes the array

   double myFancyArray[2][6] = {23, 14.12, 17,85.99, 6.06, 13, 1100, 0, 36.36, 90.09, 3.145, 5.4};

This calls the function  that returns the sum

 cout<<sumFancyArray(myFancyArray)<<endl;

This calls the function that prints the array elements

   printFancyArray(myFancyArray);

   return 0;

}
