Debug Assertion Failed!

[南气子水]

运行的时候，总有Debug Assertion Failed!
代码如下:

#include <iostream>
using namespace std;

class Kid
{
private:
	int m_nAge;
	char *m_strName;
	char *m_strSex;

public:
	Kid(int age,char *name,char *sex);
	~Kid();
	void showKid();
};
Kid::Kid(int age,char *name,char *sex)
{
	Kid::m_nAge = age;
	Kid::m_strName = name;
	Kid::m_strSex = sex;
}
Kid::~Kid()
{
	cout<<"dispose object kid"<<endl;
	delete []m_strName;
	delete []m_strSex;
}
void Kid::showKid()
{
	cout<<"姓名: "<<m_strName<<endl<<"年龄: "<<m_nAge<<endl<<"性别: "<<m_strSex<<endl;
}
int main()
{
	Kid ckid(10,"rookie_j","男");
	ckid.showKid();

	Kid *cptr = new Kid(10,"rookie_j","女");
	cptr->showKid();

	//delete cptr;这行语句去掉，依然错误.

	return 0;
}

调试程序的时候，前面都正常的，就是调试到return 0;时报错

//	delete []m_strName;
	//delete []m_strSex;注视掉。   delete和new对应

当定义ckid并没有new.ckid使用结束时，会自动调用析构函数。
就是你没有new,就delete。当然会出错！

那问题就应该处在你的析构函数中

Kid::~Kid()
{
cout<<"dispose object kid"<<endl;
delete []m_strName;
delete []m_strSex;
}

如果没有delete那句 也是依然报错的

[lee_鹿游原]

#include <iostream>
using namespace std;

class Kid
{
private:
	int m_nAge;
	char *m_strName;
	char *m_strSex;

public:
	Kid(int age,char *name,char *sex);
	~Kid();
	void showKid();
};
Kid::Kid(int age,char *name,char *sex)
{
	Kid::m_nAge = age;
	Kid::m_strName = name;
	Kid::m_strSex = sex;
}
Kid::~Kid()
{
	cout<<"dispose object kid"<<endl;
	//	delete []m_strName;
	//delete []m_strSex;
}
void Kid::showKid()
{
	cout<<"姓名: "<<m_strName<<endl<<"年龄: "<<m_nAge<<endl<<"性别: "<<m_strSex<<endl;
}
int main()
{
	Kid ckid(10,"rookie_j","男");
	ckid.showKid();

	Kid *cptr = new Kid(10,"rookie_j","女");
	cptr->showKid();

	delete cptr;
	return 0;
}

m_strName和m_strSex根本就没new，你去delete显然要报错，new和delete必须成对出现

是内存泄露问题，strlen获取的长度不包括‘\0’，用strcpy就会发生错误
