bookFill Arrays

As you remember, by accessing elements of the array, we can not only print them but also change them. For instance:


              
12345678

            
int x[2][3] { 
        {1, 2, 3},        
        {4, 5, 6}
}; 
cout << x[0][0] << endl;

x[0][0] = 100;
cout << x[0][0];
copy

Actually, we may not only change elements of the existing array but also set values:


              
12345678910111213

            
int x[2][2];

x[0][0] = 1;
cout << x[0][0] << " ";

x[1][0] = 2;
cout << x[1][0] << " ";

x[0][1] = 3;
cout << x[0][1] << " ";

x[1][1] = 4;
cout << x[1][1] << " ";
copy

Let's consolidate the acquired knowledge!
