c++ - C++调试后无显示

Question

所以我开始了我的 C++ 项目，在案例 1 之后，决定调试并确保我没有犯任何错误。唯一的问题是，没有任何显示？没有出现错误，但输出只是空白？在假设下，我一开始就完全遗漏了一些东西。请帮忙

#include <iostream> 
#include <iomanip> // for 'fixed' and 'setprecision' 
#include <cmath> // C++ Math Library

// function main begins program execution 
int main()
{
double managWage = 0;
double hourlyWorkers = 0;
double commissionWorkers = 0;
double widgetWorkers = 0;

// a variable to hold their choice 
char selection = 0;
while (selection != 'Q');
// a variable to track the number of transactions 
int transaction = 0;
{

  // Display a menu to the user 
  // You MUST use these integer values (1-5) for the auto evaluator to work 
  std::cout << "(1) Managers" << std::endl;
  std::cout << "(2) Hourly Workers" << std::endl;
  std::cout << "(3) Commission Workers" << std::endl;
  std::cout << "(4) Widget Workers" << std::endl;

  // Ask the user for their choice + Sentinel Value
  std::cout << "Enter pay code <[Q]uit>";
  std::cin >> selection;

  switch (selection)
  {
    case '1':
      //Variables
        int weekSalary = 0;
        managWage = managWage + weekSalary;

        std::cout << "Manager selected." << std::endl;
        std::cout << "Enter weekly salary ";
        std::cin >> weekSalary;
        if (weekSalary < 0)
        {
          std::cout << "Error: Weekly salary can not be less than zero.";
        }
          else
          {
            while (weekSalary >= 0)
            {
                std::cout << "Manager's pay is " << managWage << std::endl;
            } //End while
            break;
          } //End else
        break;

  }
}
}

Answer 1

这是你的问题

while (selection != 'Q');

这会导致无限循环。你可能想要:

while (selection != 'Q')
{
    int transaction = 0;
    ...

还有一个:

while (weekSalary >= 0)
