C++ 一个变量的名称占用多少字节？

charfooishness='f'

存储
f
需要1个字节，但是存储
fooishness
需要多少字节？哪里它的规模如何？我已经读过了，但它没有提到命名所需的空间

如果我有一组字符，那么它是否需要更多的存储来处理数组，而不是保存数据本身？
 名称是C++程序的短暂部分：你如何命名事物并不重要，执行代码（大部分）仍然是相同的。在名称的性质确实影响程序的可观察行为的情况下，很少有例外，例如，当使用
std:：type_info（）
时，因为它确实提供了对某种程度上类似于类型名称的实体的访问

虽然名称不影响存储的程序实体的大小，但无论它们是在堆上、堆栈上、全局内存中还是嵌入在其他对象中，名称都可能对程序本身产生大小影响：用于各种实体的名称与调试信息一起存储，调试信息通常（但不一定）贡献程序运行的大小。此外，外部引用实体的名称可能最终被用于链接器符号，特别是在使用任何形式的共享对象来解析这些对象所引用的内容时。但是，在所有这些情况下，名称都是一个恒定的大小，在某种程度上影响程序大小。
零

例如：

#include <iostream>

int main() {
    char fooishness = 'f';
    std::cout << fooishness << std::endl;
    return 0;
}

#包括
int main（）{
煤焦丰满度='f'；
STD::CUT在最终生成的代码中占用0个字节。如果你在调试模式下编译，你必须考虑到符号名称可能被存储为C风格字符字。当编译程序时，编译器将其翻译成机器代码。C++中存在的变量名称和类型信息不存在。n机器代码。因此，您担心的这些事情会占用编译程序的零空间。这可能是特定于操作系统的。因此，请阅读，这可能取决于几个因素，首先是您的体系结构CPU、芯片组、ISA等，以及您的操作系统及其文件结构，最后是您正在使用的编译器。如果您在GCC与Clang与MSVC与Intel编译器下编译，则表查找、命名约定、符号等将有所不同！！！它可能是字符串，但可能不在程序中。某些工具将调试器帮助器信息存储在单独的文件中。
