    Creates an array that assigns the initial value int a[5][4]= {{0,1},{4,5},{8,9},{12,13},{16,17}} to the 10 elements of the first two columns in the array;
    Keyboard input after two columns 10 elements of the value cout<< "Please enter 10 integers:" <<endl;
        For (i=0, i<=4; ++i) {for (j=2; j<=3; ++j) {cin>>a[i][j];
    }}//by row order precedence output cout<< "The value in the array is:" <<endl;
        for (i=0; i<=4; ++i) {cout<< "No. <<i<<" line: ";
            for (j=0; j<=3; ++j) {cout<<a[i][j]<< ' \ t ';
        if (j%3==0&&j!=0) cout<<endl; }}//Multiply all element values by 3 and save in the array cout<< "now multiply all elements by 3 times times ... Complete.
