Question

在Visual Studio中，您可以自定义任何显示项的字体和颜色，例如C ++关键字，C ++参数，C ++局部变量，函数名称，宏等。您可以通过选择菜单“工具 - ＆gt;”来完成此操作。选项 - ＆gt;字体和颜色“。

在设置对话框中，我对两个“显示项目”感到困惑：“C ++ Local Variables”和“C ++ Variables”。

“C ++ Local Variables”很容易理解。说：

void f()
{
    int this_is_a_Cpp_Local_Variable;
}

我可以将C ++局部变量设置为我喜欢的任何字体和颜色。

然而，我无法理解“C ++变量”是什么。我已经测试并证明它们不是全局变量，无论全局变量是基本类型还是用户定义类型。

我的问题是：Visual Studio的“显示项目”中的“C ++变量”是什么？

更新

我的测试代码是：

#include <iostream>
#include <functional>

using namespace std;

class A
{
public:
    int n;
};

A a;

class B
{
public:
    B()
    {
        int v;
        a.n
    }
};

void f(A a)
{
    a.n;
}

int main()
{
    int v;
    A a;
}

Answer 1

正如您所看到的，它突出显示了C ++项目中不同类型的变量。这是带有自定义颜色方案的Visual Studio 2012。

blue := local
green := global variable

所以这是我的设置突出显示的代码：

这是您的colorsettings，背景颜色为红色的局部变量

Visual Studio“显示项目”中的“C ++变量”是什么？
