So I'm new to c++ coding and have to do a module on it for uni

I've got a worksheet about for and while loops
I need to create a loop that outputs this:
1
12
123
1234
12345
123456

It has to be inside a loop I cannot just used std::cout
If anyone has any ideas or ways to help that would be great

You can use any type of loop for this. You simply need to exit the loop once your variable matches 6.


For Loop

for (int i = 1; i <= 6; i++) {
  // output i
}



Do Loop

int i = 1;
do {
  // output i
  // increase i
} while (i <= 6);



While Loop

int i = 1;
while (i <= 6) {
  // output i
  // increase i
}

Thankyou so much
I've not really done much C++ and I have a whole sheet on loops to do by tomorrow,
there is 6 exercises and I've done 4
Also If I wanted It to print something like
THIS:
1*****
12****
123***
1234**
12345*
123456

Could you tell me how I would go about that?

If you take 6 minus whatever the current value is and the do a for loop for that many times.

Example based on the do loop.


Do Loop

int i = 1;
do {
  // output i
  for (var j = 6 - i; j > 0; j--) {
    // output *
  }
  // increase i
} while (i <= 6);


Here the for loop for j will start at 5 and each iteration of the do loop will result in j getting smaller.
This means that for the first loop: i = 1, j = 5. 2nd loop: i = 2, j = 4. etc.

Is this for the console or a GUI?

Thanks for the help again I'm really quite lost here
Also I'm not sure what its for, we've been given a sheet to practice Imbricated loops and I have very little knowledge in the area, so I'm just trying to get the specified output in Visual Studios
