My program is not outputting the results of processUserOptions(); What's the issue?

I refactored my code and now it's only outputting 'You wrote x' when executed. Its also supposed to output a certain statement depending on the number entered into the terminal. I even made sure to compile everything again from scratch in case there were problems with the compilation.

I'm not sure what else to do. I would appreciate your help on this.

#include <iostream>

void printMenu()
{
    // 1 print help
    std::cout << "1: Print help" << std::endl;
    // 2 print exchange stats
    std::cout << "2: Print exchange stats" << std::endl;
    // 3 make an offer
    std::cout << "3: Make an offer" << std::endl;
    // 4 make a bid
    std::cout << "4: Make a bid" << std::endl;
    // 5 print wallet
    std::cout << "5: Print wallet" << std::endl;
    // 6 continue
    std::cout << "6: Continue" << std::endl;

    std::cout << "==============" << std::endl;
