C程序 - 转换为二进制整数 [英] C Programming - Convert an integer to binary

问题描述

我是希望以后反对的解决方案，因为这一些技巧是功课，我想解决它自己

i was hopefully after some tips opposed to solutions as this is homework and i want to solve it myself

我首先很新的C.事实上，我从来没有做过任何之前，虽然我从在大学模块previous java的经验。

I am firstly very new to C. In fact i have never done any before, though i have previous java experience from modules at university.

我试图写在二进制一个整数转换的程序。我只允许使用位运算，没有库函数

I am trying to write a programme that converts a single integer in to binary. I am only allowed to use bitwise operations and no library functions

任何人都可以提出可能对我怎么会去这样做的一些想法。很明显，我不想code或任何东西，只是一些想法什么门路我有点困惑，并没有攻击计划，以探索为currenty。好了，让了很多困惑：D

Can anyone possibly suggest some ideas about how i would go about doing this. Obviously i dont want code or anything, just some ideas as to what avenues to explore as currenty i am a little confused and have no plan of attack. Well, make that a lot confused :D

非常感谢

推荐答案

想想你可以用按位运算符做什么。

Think about about what you can do with bitwise operators.

例如。您可以测试一个位是1或0这样的：

E.g. you can test whether a bit is 1 or 0 like this:

int bit = value & 1;

您也可以在这样一个int位转移：

You can also shift the bits in an int like this:

val = val >> 1;

要测试的第i位在一个int你可以这样做：

To test the i'th bit in an int you can do this:

int bit = (value >> i) & 1;

我希望这足够的提示，让你开始。

Hopefully that's enough hints to get you started.
