c++ array storing and sorting.

jamesnope (1)
So i am suppose to create 3 arrays. one to take the first input, the second to take the second input, and third is to store both input and sort them from least to greater.
here is what suppose to happen

please enter your first input: (file name contains-> " 1,3,5,6,7,9 ")
please enter second input: (second file name contains-> "1,2,4,6,8,0")
please enter the outfile name: (any name you want)
here is your file number
1
1
2
3
4
5
6
6
7
8
9
end

then it creates another file with the number from both files organize from least to greater form.

So, do you have any questions?

Your SortedArray(...) does not sort. You need an inner loop that finds the lowest value and another for inserting.

Imagin the numbers come as: 2,3,4,1
