gcc编译错误如何解决

[wonderfull_zhb]

有以下程序，在Linux下用gcc编译成可执行代码错误如下：

a2.c:

#include <string.h>

class CName
{
char m_szFirst[256];
char m_szLast[256];
public:
void SetName(char* pszFirst, char* pszLast)
{
strcpy(m_szFirst, pszFirst);
strcpy(m_szLast, pszLast);
}
};

int main()
{
char* pCharArray = new char[256]; // Allocate memory for the array
strcpy(pCharArray, "Array of characters");
delete [] pCharArray; // Deallocate memory for the array
pCharArray = NULL;
CName* pName = new CName; // Allocate memory for the object
pName->SetName("Firstname", "Lastname");
delete pName; // Deallocate memory for the object
pName = NULL;
}


用gcc -o a2 a2.c进行编译，错误如下：
a2.c:3: error: syntax error before "CName"
a2.c:4: error: syntax error before '{' token
a2.c:7: error: syntax error before ':' token
a2.c:11: warning: parameter names (without types) in function declaration

main函数怎么没有return

[珍惜生命远离CPP]

gcc -o a2 a2.c 这是编译C程序的
a2.c改为a2.cpp

然后用
g++ -o a2 a2.cpp

[fallening]

用g++编译，这里是c++程序，不是c程序

[K行天下]

#include <cstring>
using namespace std;

要么你用g++，要么你用gcc -x c++
