反转C中的字符串 [英] Reversing strings in C

问题描述

如何编写一个用于显示反向字符串的ac程序，以显示每个字符之间的字符"x"，例如:(oxlxlxexh)

how to write a c program for display reverse string with characters "x" in between each character eg:(oxlxlxexh)

推荐答案

对于初学者... C没有不是真的有字符串...字符串是字符数组，应该使反转更简单(直观).

考虑一下(伪代码)...

For starters... C doesn''t really have strings... strings are character arrays, which should make reversing even simpler (intuitively).

Think about it (pseudo-code)...

char word[]="hello";
/*
so the characters...
*/
word[0] = ''h'', word[1] = ''e'', word[2] = ''l'', word[3] = ''l'', word[4] = ''o''
/*
if you want to reverse that, what''s the simplest way? ...::cough cough:: _index_ ::cough::
*/
word[4] = ''o'', word[3] = ''l'', ...
/*
Of course, you can add loops to make that more efficient code

Now to add the ''x'' character, well, that''s easy too... just transfer onto a larger array and add those extra characters into it...  to make it a bit more flexible, look at dynamic memory allocation of character arrays using malloc() and free()
*/

这确实是一个简单的(我想说是基本的)任务.您只需要阅读有关C编程语言的精彩教程并开始编码.然后，如果您有任何问题，请随时在此处发布特定问题.

This is really a simple (I would say basic) task. You have just to read a good tutorial about C programming language and start coding. Then, if you have any problem feel free to post here specific questions here.
