C++ Program For Printing A 2D-Array [Two Dimensional] Onto The Screen/Console.

/* Declaration Of Header Files */
#  include  <iostream.h>
#  include  <conio.h>

/* Start Of Main Program */
void main()
{
   
       /* Declaration Of Variables */
       int  i,  j,  r  =  0,  c  =  0;
       int  a [ 10 ][ 10 ];
       clrscr();

       /* Asking For The Input From User */
       cout  <<  "  Enter Number Of Rows & Columns Of 2D Array [ Matrix ]  :  ";
       cin  >>  r  >>  c ;
      
       //  Accepting Values Of 2D Array [ Matrix ]
       cout  <<  "  Enter  "  <<  r  *  c  <<  "  Values for 2D Array  :  ";
       for  (  i  =  0;  i  <  r;  i++  )
       {
                for  (  j  =  0;  j  <  c;  j++  )
                {
                         cin  >>  a [ i ][ j ];
                }
       }

       // Printing Values Of 2D Array [ Matrix ]
       cout  <<  "  Values Of 2D Array [ Matrix ] Are  :  ";
       for  (  i  =  0;  i  <  r;  i++  )
       {
                cout  <<  " \n ";
                for  (  j  =  0;  j  <  c;  j++  )
                {
                         cin  >>  a [ i ][ j ];
                }
       }
       getch();
}
/* End Of Main Program */ 

Output  :

Enter Number Of Rows & Columns Of 2D Array [ Matrix ]  :  3  3

Enter 9 Values For 2D Array [ Matrix ]  :

1  2  3  4  5  6  7  8  9

Values Of 2D Array [ Matrix ] Are :
1  2  3

4  5  6

7  8  9
