    Concern over vector length

    I intend to incorporate a feature allowing a user to recall strings input at the console using the arrow keys by storing them in a vector.

    My concern is the size of the vector growing too large through extended use of the program.

    Would there be a better structure to store

    Code:
    std::string
    I like the idea of the vector because I can use an iterator

    Code:
    vector<string>::Iterator it
    to scroll through the input. I am still learning C++ and I appreciate the input received in this thread.

    Of course, the second way is more clean and flexible.

    >> My concern is the size of the vector growing too large through extended use of the program.

    Average largest line: 80 characters
    Average largest amount of lines: 300

    300*80 = 24,000 characters: Almost 23.5 KBytes ( assuming the console uses 1-byte characters )

    Is that too big?

    A vector uses dynamic memory internally, so you are not storing any of that on the stack. Based on your description of what you are doing this approach will work fine.
