在C动变量声明 [英] Dynamic variable declaration in C

问题描述

我是一个Ruby开发者和被长久以来我一直C. codeD我有这个小问题-Basically我想用用C其行为类似于C的符号的数据类型。

I'm a ruby developer and its been long since I've coded in C. I have this small issue -Basically I want to use a datatype in C which behaves like a symbol in C.

在换句话说，这是可能用C？

In other words, is this possible in C?

• 程序将要求用户输入名称


• 用户回复 - foobar的



• 声明具有相同的名称即一个整数。

• Program asks user for name
• user replies - "foobar"

• declare an integer with the same name i.e.

INT foobar的

int foobar

推荐答案

不像间preTED语言，对C在运行时不变量名的字典。存在在运行时没有变量名都没有。因此，遗憾的是它是不可能做到在C想要的东西。

Unlike in interpreted languages, C does not have a dictionary of variable names at runtime. There exist no variable names at runtime at all. Hence unfortunately it is impossible to do what you want in C.
