当编译期间分配的内存？ [英] When is memory allocated during compilation?

问题描述

当我写

int main()
{
    int j;
}

有J的存储器被编译期间在编译的时间分配，但是当？当存储器被分配给一个变​​量有哪些不同编译阶段？如果结果表明：J全球性的？

The memory for 'j' is allotted at the time of compilation,but when during compilation ? What are the various stages of compilation when memory is allotted to a variable? What if j was global ?

推荐答案

我猜你是混合的东西了。

I guess you are mixing things up.

编译器不变量分配内存 - 它产生code，它在运行时为变量分配内存。对于全局的将被添加到程序启动code。

Compiler doesn't allocate memory for variables - it generates code that allocates memory for variables at runtime. For globals is will be added to program start-up code.
