I have read in the data from a file and have given the user multiple options on what they are allowed to do one of which is to edit lines of data. i created an infinite for loop that ends only when the user uses x or X when the edit option is chosen i have altered the vector but later on if i have user use the view option the vector seems unchanged
Why is it that although the vector is altered then asked to print out its info again alter on that it prints the older version of the vector but if you print the vector it shows its been altered

Dragcave.com
as you can see dragcave.net became .com but if you run through and print out using the V code it shows .net still
