gcc和g++的区别
gcc和g++的区别我们在编译c/c++代码的时候，有人用gcc，有人用g++，于是各种说法都来了，譬如c代码用gcc，而c++代码用g++，或者说编译用gcc，链接用g++，一时也不知哪个说法正确，如果再遇上个extern "C"，分歧就更多了，这里我想作个了结，毕竟知识的目的是令人更清醒，而不是更糊涂。
误区一:gcc只能编译c代码,g++只能编译c++代码
两者都可以，但是请注意：
1.后缀为.c的，gcc把它当作是C程序，而g++当作是c++程序；后缀为.cpp的，两者都会认为是c++程序，注意，虽然c++是c的超集，但是两者对语法的要求是有区别的，例如：
<div style="padding-right: 5.4pt; padding-left: 5.4pt; background: #e6e6e6; padding-bottom: 4px; width: 95%; padding-top: 4px;">http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif#include<stdio.h>
