Question

array function
• Create a function called show2D.
• This function should accept a two-dimensional array as parameter and display its contents that are odd numbers on the screen.
• This function should work with any of the following arrays of different sizes:

int hours[3][9];
int stamps[7][9];
int cities[15][9];

• Write a demo program to show how to use the function show2D.

Task 2: Array functions • Create a function called show2D. • This function should accept a two-dimensional array as parameter and display its contents that are odd numbers on the screen. • This function should work with any of the following arrays of different sizes: int hours[3][9]; int stamps[7][9 l; int cities[15][9 l; • Write a demo program to show how to use the function show2D.

this is c++ program

Answer 1

I WROTE THE CODE ALONG WITH THE COMMENTS

I AM USING ONE 2D ARRAY { hours[3][9] }

CODE:

#include <iostream>

using namespace std;

//global variables initialization.
int const N=3;
int const M=9;
void show2D(int hours[N][M])
{
//variables declaration.
int i,j;
  
cout<<"\nOdd numbers of the 2D array: ";
for(i =0;i<N;i++) //for loop used to go row wise.
{
for(j=0;j<M;j++) //for loop used to go columns wise.
{
if(hours[i][j]%2!=0) //condition for odd number.
cout<<hours[i][j]<<" ";
}
}
}
int main()
{
  
//variables declaration.
int hours[N][M],i,j;
  
cout<<"Enter 2D Array: "<<endl;
for(i=0;i<N;i++) //input scanning.
{
for(j=0;j<M;j++)
{
cin>>hours[i][j];
}
}
show2D(hours); //calling the show2D() function.

return 0;
}

OUTPUT:

Enter 2D Array: 1 2 3 4 5 6 7 8 9 10 9 11 8 12 7 13 6 14 15 5 16 4 17 3 18 2 19 odd numbers of the 2D array: 1 3 5 7 9 9 11 7 13 15 5 17 3 19 ... Program finished with exit code 0 Press ENTER to exit console.]
