just keep learning cpp and try to ask google sometimes😉

Answer 2

@Timon cuz if he asks such questions he didnt know anything about vectors, dynamic arrays are more easy for understanding

Answer 3

Thanks this helped me a lot!

Answer 4

@Curios i ve refreshed the code, look

Answer 5

@Timon im pretty sure that at the beginning of the studying he doesnt make such big projects to cause memory leaks, time will come and he will use vectors☺

Answer 7

@Curios

just take an input of 'm' and fill the array with it

Answer 8

Ohh now I get that, here we are using n as
a[n] [n] ;

Answer 9

'n' rows, 'm' columns

Answer 10

If I give the values 3 and 4 to n and m respectively, does it mean the same as if I have declared an array
a[3] [4] ;

Answer 11

@Curios Im sorry) 'n' columns, 'm' rows, was busy, didnt look at variables

Answer 12

And how to do the same in 2D array?

Answer 13

Yes, I'm beginner in the field of programming.

Answer 14

@01ejka I want to declare an 2D array of user's choice

Answer 15

No, that's not the case. I want m and n of user's choice declaring as array[m] [n] ;

Answer 16

Wow, great thank you so much! @01ejka
Here, m and n stands for what row or column?

Answer 17

Ok, it's possible. But why should you do this instead of using a vector?
I mean, yes, there are some edge cases, but generally said, you want to use vectors for array-like data in the heap.

Answer 18

Ok, Curios Basant, please don't use this for arrays with a size greater than 10,000,000. Because if you're unlucky, you'll have to start your device again after that. Just in case you get the idea.

Answer 19

No, if he can't use vectors, he'll do memory leaks with dynamic arrays.

Answer 20

Just in case you're interested.
