Reading and input testcases in c++


Here I ask how to input test cases and read array of integers input in programming logic I know logic but I don’t know how to input testcases and other integers and their datatypes

just take input in array using loop (in cpp)

I am asking in competitive programming questions

Could you please explain how to input testcases ,arrays of integers like
4
1 2 3 4
10 20 30 40
Here 4 is size and next two lines are N-separated integers so tell how you take this
N can vary 1<=N<=10000

You just take input and calculate answer. Put this whole thing into a loop of testcases.

Please you write some code

I have seen many codes I don’t know which is good way

How many testcases are there in ur example? Elaborate the question.

Here there is N size of array which can be from1<=N<=10000 and next 2 lines N-separated integers in range N
So how you will take this as input in c++ plz write code

Refer to this:

It’s easy I know already this
How to take in 1 line array input like in coding competitions
1 2 3 4
10 20 30 40
Like this plz write code in this if you know
