A nested loop is fairly straight forward, its how you plan to store and access the data that can be a little challenging. You said ‘without arrays’, have you considered using vectors?

Then you don’t have to store the values, which makes things much simpler. Since this is a homework assignment I won’t give you the complete answer, but this will get you started: for(int i = 0; i < 3; i++) { for(int j = 0; j < 3; j++) { cout << “some number”; } cout << “something else”; } Play around with that a little and you will have the answer. 😊

No I haven't tried with vectors. As I'm a beginner and I don't know how to use vectors.

In that case using vectors for a 2D matrix might be a bit advanced. What are the other constraints / expectations if you cannot use arrays?

I was given an assignment in which it said that we have to use nested loops(for,while,do-while) and show the output of 123 456 789
