BAC计算器在到达主函数之前一直以退出代码0x0结束 我试图用C++编写一个BAC计算器，但是程序在退出程序之前一直以退出代码0x0结束。我做错了什么 #include <iostream> #include <string> using namespace std; double Calc(double& value_one, double& value_two, double& value_three, double& value_four, double& value_five, double& value_six, double& value_seven, double& value_eight, double& age, double& weight, double& gender);

一个明显的错误在您的

main

中：

    double Calc(double& value_one, double& value_two, 
                double& value_three, double& value_four, 
                 double& value_five, double& value_six, 
                 double& value_seven, double& value_eight, 
           double& age, double& weight, double& gender);   // Function Call

您正在执行函数声明，如果正在执行函数调用，请执行以下操作：

double res = double Calc(value_one,value_two, value_three, 
         value_four, value_five, value_six,  
          value_seven, value_eight, age, weight, gender);  

您需要稍后在

main

中使用返回的结果

---

此外，将

age

和

gender

声明为

double

是没有意义的。我刚刚编译并运行了您的代码。它按预期运行

g++4.9.2没有标志

但是你有很多语法是荒谬的，例如

if (BAC > .01) (BAC < .05),  degreeofdrunkness1 = "Subclinical";

if（BAC>.01）（BAC<.05），degreeofdrunkness1=“亚临床”；

您所说的“程序在到达主功能之前一直结束”是什么意思？您看到了什么输出？这就是它，一旦它到达函数调用，它就会以代码0x0退出，这就是输出。它只是跳过所有其他内容并停止运行。嗯，听起来是一个很好的调试器使用案例。它实际上已经很好地通过了调试器。是的，但我尝试在microsoft visual studio中运行它在C++中，它显然在第一个函数调用之前结束。我试图重新定义代码为浮点，并且在函数调用被注意之前仍然结束。函数被调用并以写的方式运行。您对工具和C++不熟悉。
