Write a code in C++, that declares an array of int type having the size of user's choice.

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

@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☺

@Curios https://code.sololearn.com/cbaJZnBBgxRA/?ref=app just take an input of 'm' and fill the array with it

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

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] ;

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

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.

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.

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