在汇编中声明和访问字符串(32位Debian CommandLine OS) [英] Declaring and Accessing Strings in Assembly (32-bit Debian CommandLine OS)

问题描述

首先，这是一项家庭作业，但我终生无法在网上找到任何可靠的资源来解释教授使用的语法.

First off, this is a homework assignment but I cannot for the life of me find any reliable resources online that explain using the syntax my professor has us using.

我想在这方面先做功课，以免直接得到答案，而是要求解释，以便将来学习.我的教授不是最擅长提供学习这些知识的资源，因此我决定向SO的优秀人才寻求帮助.

I wanted to be up front about this being homework so as not to get an answer straight up but to ask for an explanation so I can learn for future reference. My professor is not the best at providing resources for learning this stuff so I've decided to turn to the great people here at SO for assistance.

任务很简单.使用一个字符串数组(北约军事字母)，从用户那里接收一系列单词，然后以军事字母的形式将这些单词输出到屏幕上.

The assignment is fairly straight forward. Using an array of strings (the NATO Military Alphabet), receive a series of words from the user and then output that series of words to the screen in military alphabet.

因此，例如，输入"Feed"被输入.将会输出为:

So for example, the input "Feed" would be output as:

Foxtrot  
Echo  
Echo  
Delta

我的问题很基本.如何在Assembly中声明一个字符串数组(我很确定我使用的是AT& T语法，因为它在变量和寄存器之前使用$和％)?

My question is quite basic. How does one declare a string array in Assembly (I'm fairly certain I'm using AT&T syntax since it using $ and % before variables and registers)?

感谢您的提前帮助！让我知道是否需要详细说明，我很乐意这样做.

Thanks for the help in advance! Let me know if I need to elaborate at all, I'll be happy to do so.

因此，通过评论中的一些解释，到目前为止，我已经提出了用于定义地址数组的方法，这些地址指向军事字母的asciz值.

So with some explanations from the comments, I've come up with this so far for defining an array of addresses which point to asciz values for the military alphabet.

.section .data

Alpha:     .asciz "Alpha"
Beta:      .asciz "Beta"
Charlie:   .asciz "Charlie"
Delta:     .asciz "Delta"
Echo:      .asciz "Echo"
Foxtrot:   .asciz "Foxtrot"
Golf:      .asciz "Golf"
Hotel:     .asciz "Hotel"
India:     .asciz "India"
Juliet:    .asciz "Juliet"
Kilo:      .asciz "Kilo"
Lima:      .asciz "Lima"
Mike:      .asciz "Mike"
November:  .asciz "November"
Oscar:     .asciz "Oscar"
Papa:      .asciz "Papa"
Quebec:    .asciz "Quebec"
Romeo:     .asciz "Romeo"
Sierra:    .asciz "Sierra"
Tango:     .asciz "Tango"
Uniform:   .asciz "Uniform"
Victor:    .asciz "Victor"
Whiskey:   .asciz "Whiskey"
Xray:      .asciz "X-Ray"
Yankee:    .asciz "Yankee"
Zulu:      .asciz "Zulu"

MAlpha:    .long Alpha, Beta, Charlie, Delta, Echo, Foxtrot, Golf, Hotel, India, Juliet, Kilo, Lima, Mike, November, Oscar, Papa, Quebec, Romeo, Sierra, Tango, Uniform, Victor, Whiskey, Xray, Yankee, Zulu
