Is it always necessary that while passing array we need to mention the size in the parameter.And also wanted to know why in the lecture only column size is being provided in parameter and not row?
ARRAY SIZE in parameter
@Prakhar_Nagpal no its now always necessary to pass size. like for example if you declare sizes globally aur used inbuilt stl so that you can access size using function. As there is no point in passing array without the ability to traverse it.
2nd question - its just a way of passing 2d array specify col size not row , u can see more styles of passing by google.
hope its clear if yes don’t forget to mark it as resolved and hit like
