如何将字节数组转换为字符串？ [英] How to convert a byte array to a string?

问题描述

大家好，

我使用多播并通过网络接收压缩数据包。我在指定的内存块'''''解压缩数据包（声明为lzo_byte * in）... 。现在，我想将''in'转换为字符串并在控制台上显示结果（并将其保存在磁盘上）...我该怎么做？


任何帮助都会非常实用....

提前致谢....干杯

Hello all,
I used multicasting and received compressed data packets over the network.I decompressed the packets at a specified memory block ''in''(declared as lzo_byte *in)....Now,i want to convert ''in'' to a string and display the result on the console(and also save it on disk)...How do i do this?

Any help will be really useful....
Thanks in advance....Cheers

是字节有意义的字符或整数数字数据中的信息？

最简单的方法是让一个for（）循环通过数组以你需要的格式打印每个元素。

is the information in the bytes meaningful characters or integer numeric data?
The simplest thing is to have a for() loop go thru the array printing each element in the format you require.

感谢您的快速回复....

内存块in有积分值和字符....我已经在捕获数据包时使用了''for（）''循环.....所以''in''的每个元素都已经占了...我现在如何在文件中写出来？


干杯

Thanks for the quick response....
The memory block "in" has integar values as well as characters....I have already used a ''for()'' loop while capturing the data packets.....so every element of ''in'' is already accounted for...how do I write it in a file now?

你可以在C中使用fopen（）打开一个文件

http://www.cplusplus.com/fopen


或C ++中的ostream

http：//www.cplusplus .com / reference / iostream /


你可以写出二进制信息，例如您的字节数组，或字符和/或数字文本表示

http://www.cplusplus.com/doc/tutorial/files.html

you can open a file using fopen() in C
http://www.cplusplus.com/fopen

or ostream in C++
http://www.cplusplus.com/reference/iostream/

you can either write out binary information, e.g. your byte array, or the character and/or numeric text representation
