如果是只有幾個cpp文件，用文本編輯器軟體查看源碼就可以了，根據個人喜好來選擇，常見的編輯器比如gedit、VScode、Sublime Text都可以；如果是一個項目，裡面有很多源碼文件，經常需要在不同的源碼文件之間切換，用文本編輯器軟體查看就沒有那麼方便了，這時推薦用專門的源碼閱讀軟體Source Insight，這個軟體只有Windows版，但是它在Linux的Wine環境中運行的非常好，所以在Linux上安裝一個wine就可以用這個軟體了，這個軟體可以很方便的跳轉到變數、函數、類的定義處，還能前進、後退，閱讀源碼非常方便。
3. 我下載了一個小游戲源碼，裡面有好幾個CPP文件這是為什麼
不是的，一個程序一個的那是main函數，多個cpp文件是對整個程序分塊編程，這樣你看主程序的時候會比較清晰，而不是一大團代碼擠在一塊，並且這么多cpp文件中只有一個main函數
4. 如何用c++輸出該程序本身的源代碼
//這個很簡單，比如xxx.cpp文件
#include<stdio.h>
FILE*a=fopen("xxx.cpp","r");
intmain()
{charc;
/*
很多代碼。。。
*
/
while(!feof(a))
{
c=fgetc(a);
putchar(c);
}
getchar();
}
//這樣就可以了
5. 有什麼工具可以檢測 C++ 代碼抄襲嗎
本文淺談一下C++內存泄漏的檢測，首先我們需要知道程序有沒有內存泄露，然後定位到底是哪行代碼出現內存泄露了，這樣才能將其修復。最簡單的方法當然是藉助於專業的檢測工具，比較有名如BoundsCheck工具,功能非常強大，相信做C++開發的人都離不開它。此外就是不使用任何工具，而是自己來實現對內存泄露的監控，分如下兩種情況：一.在MFC中檢測內存泄漏假如是用MFC的程序的話，很簡單。默認的就有內存泄露檢測的功能。我們用VS2005生成了一個MFC的對話框的程序,發現他可以自動的檢測內存泄露.不用我們做任何特殊的操作.仔細觀察,發現在每個CPP文件中,都有下面的代碼:#ifdef_DEBUG#definenewDEBUG_NEW#endifDEBUG_NEW這個宏定義在afx.h文件中，就是它幫助我們定位內存泄漏。在含有以上代碼的cpp文件中分配內存後假如沒有刪除，那麼停止程序的時候，VisualStudio的Output窗口就會顯示如下的信息了：Detectedmemoryleaks!Dumpingobjects->d:\code\mfctest\mfctest.cpp(80):{157}normalblockat0x003AF170,4byteslong.Data:00000000Objectmpcomplete.在Output窗口雙擊粗體字那一行，那麼IDE就會打開該文件，定位到該行，很容易看出是哪出現了內存泄露。二．檢測純C++的程序內存泄露我試了下用VisualStudio建立的Win32ConsoleApplication和Win32Project項目，結果都不能檢測出內存泄露。下面一步一步來把程序的內存泄露檢測的機制建立起來。首先，我們需要知道C運行庫的Debug版本提供了許多檢測功能，使得我們更容易的Debug程序。在MSDN中有專門的章節講這個，叫做DebugRoutines，建議大家先看看裡面的內容吧。我們會用到裡面很重要的幾個函數。
6. c＋＋編寫的.cpp源代碼怎麼執行
菜單build目錄下面點擊build solution，然後點擊Debug下的start就可以了
7. 在VC++6.0中編譯下面的代碼後怎麼解決出現的那個問題
確保兩個源代碼文件在同一目錄下；
確認文件都已經加入到同一工程中；
確認工程文件已保存。
8. cppcheck怎麼安裝和實用
首先先下載 成功後：
編譯：
g++ -o cppcheck -Ilib cli/*.cpp lib/*.cpp
安裝：
make install
cppcheck默認安裝會報錯如下：
cppcheck: unusedFunction check can't be used with '-j' option. Disabling unusedFunction check.
(information) Failed to load std.cfg. Your Cppcheck installation is broken, please re-install. The Cppcheck binary was compiled without CFGDIR set. Either the std.cfg should be available in cfg or the CFGDIR should be configured.
因此我直接不用他們的make，而是直接使用g++參數編譯：g++ -o cppcheck -Ilib cli/*.cpp lib/*.cpp
然後就是檢查了
cppcheck -j 3 --enable=all src/
使能檢查規則：
默認：--enable=error
--enable=all
--enable=unusedFuntion path
--enable=style
規則定義：
error：出現的錯誤
warning：為了預防bug防禦性編程建議信息
style：編碼格式問題（沒有使用的函數、多餘的代碼等）
portablity：移植性警告。該部分如果移植到其他平台上，可能出現兼容性問題
performance：建議優化該部分代碼的性能
information：一些有趣的信息，可以忽略不看的。
保存結果到文件中：重定向「>」
-j 3 使用3個線程，如果代碼工程太大，可以使用15-20個，自己隨意發揮，不過還是參考cpuinfo
如果是Windows的版本呢，就這樣使用：
1、將Cppcheck綠色版cppcheck.rar解壓；
2、打開cppcheckgui.exe；
3、菜單 check->directory；
4、選擇源代碼目錄，確認；
5、Cppcheck自動開始走查；
9. 求一份c語言的RTP音頻傳輸源碼
1.項目前期工作（配置好環境）
2.發送端文件編寫（見下面的send.cpp）
3.接收端文件編寫（見下面的receive.cpp）
4.編譯文件
（1）發送端
g++-osendsend.cpp-I/usr/local/include/jrtplib3/-ljrtp
（2）接收端
g++-oreceivereceive.cpp-I/usr/local/include/jrtplib3/-ljrtp
附錄：
（1）send.cpp
