Explanation:-

2D-Array is a collection of rows and columns and we also called as array of arrays.

Source code:-

Output:-

Source code:-

 For create a matrix.

 

 

Output:-

 

 

 

 

 

 

 

Source code:-

For displaying matrix.

 

Code:-

 

For Exiting the program:-

 

Executable Code :-

#include<iostream>

using namespace std;

int matrix[10][10],i,j,row,col;

void create(int matrix[10][10],int row,int col);

void display(int matrix[10][10],int row,int col);

int main()

{

         int ch,r,c,a[10][10];

         do{

                 cout<<"Creating Matrix and Displaying Matrix\n";

                 cout<<"1.Create Matrix\n2.Display Matrix\n3.Exit\nEnter your choice:";

                 cin>>ch;

                 switch(ch)

                 {

                 case 1:

                          cout<<"Enter the row for matrix:";

                          cin>>r;

                          cout<<"\nEnter the column for matrix:";

                          cin>>c;

                          create(a,r,c);

                 break;

                 case 2:

                          display(a,r,c);

                 break;

                 case 3:

                          cout<<"\nExiting....";

                          exit(0);

                 break;

             }

         }while(ch!=3);

}

void create(int matrix[10][10],int row,int col)

{

         for(int i=1;i<=row;i++)

         {

                 for(int j=1;j<=col;j++)

                 {

                          cout<<"Enter the element at "<<i<<j<<" = ";

                          cin>>matrix[i][j];

                 }

         }

}

void display(int matrix[10][10],int row,int col)

{

         for(int i=1;i<=row;i++)

         {

                 for(int j=1;j<=col;j++)

                 {

                          cout<<matrix[i][j]<<"\t";

                 }

                 cout<<"\n";

         }

}
