函数返回未分配给变量 [英] function return not assigned to a variable

问题描述

如果调用(非无效)函数但不将其返回值分配给变量怎么办?例如getchar();

What if you call a (non-void) function, but don't assign its return value to a variable? e.g., getchar();

我一直想知道这样的值会发生什么.我听过幽默的解释，例如它降到了以太"等等，但是我真的很想知道.有什么办法可以恢复这样的价值?谢谢

I've always wondered what happens to such a value. I've heard humorous explanations like "its gone to the ether" and so forth, but I'd really like to know really. Would there be any way to recover such a value? Thanks

推荐答案

不，您不会.

该值从堆栈中弹出并消失.

The value gets popped off the stack and is gone.

如果需要返回值，则应将其分配给变量.

If you need the return value, you should assign it to a variable.
