Answer 1

You can do cascading for multiple inputs i.e, multiple cin.

Answer 2

If I use multiple cin then I have to declare all value part by part or use array...I already said that I don't know array length...I hear about vector lib but I don't know how to use...

Answer 3

First, input a n of numbers you want to sum. Then input your numbers
Example: 3 4 5 1
3 is n,
4, 5, and 1 is your number
Output is 10
