Thread: looping, for,while,do-while.

can anyone please do this problem

1 2 3 4
2 4 6 8
3 6 9 12
4 8 12 16

in for loop, while loop, and do-while,,

ill study how this works in these three different structures of loop

tnx a lot!!

oh sori sir..

i've just red it on my school mate a while ago.

it says

do that program by using a loop(i dont remember all the details)

but i think that

the first number (number 1) will be initialized then it will increment up to (4). (THE FIRST ROW)

1 2 3 4

but im having some trouble formulating the idea on how to loop the next numbers ,(2nd 3rd and 4th row)

2 4 6 8
3 6 9 12
4 8 12 16

    for(int i = 1; i <= 4; ++i) {
       System.out.print(i + " ");
    }
 
    System.out.println("");
 
    for(int i = 2; i <= 8; i += 2) {
       System.out.print(i + " ");
    }
 
    System.out.println("");
 
    for(int i = 3; i <= 12; i += 3) {
       System.out.print(i + " ");
    }
 
    System.out.println("");
 
    for(int i = 4; i <= 16; i += 4) {
       System.out.print(i + " ");
    }

That should print what you want I guess.

1 2 3 4
2 4 6 8
3 6 9 12
4 8 12 16
