Maybe this piece of code could work? (I'm not an expert):

//Header files up here

bool thinkingProcessDone = false;

int main()
{
    string name;
    getline(cin, name);
    //Think and show progres bar
    thinkingProcessDone = true;
    cout << "Ended with exit code 1";
    if (thinkingProcessDone) {
    getchar();
    }
    return 1;
}

This might not be what you're asking, but it's the best I can come up with.
