class CDog
{
public:
unsigned int m_Weight;
unsigned int m_Age;
CDog();
~CDog();
};
CDog::CDog()
{
m_Age=1;
m_Weight=2;
printf("sonstruct instance\n");
}
CDog::~CDog()
{
}
int main(int argc,char*argv[])
{
CDog mydog;
printf("%d",mydog.m_Age);
return 0;
}
{
public:
unsigned int m_Weight;
unsigned int m_Age;
CDog();
~CDog();
};
CDog::CDog()
{
m_Age=1;
m_Weight=2;
printf("sonstruct instance\n");
}
CDog::~CDog()
{
}
int main(int argc,char*argv[])
{
CDog mydog;
printf("%d",mydog.m_Age);
return 0;
}
可以运行啊，你没有加头文件么
#include<iostream>
using namespace std;
class CDog
{
public:
unsigned int m_Weight;
unsigned int m_Age;
CDog();
~CDog();
};
CDog::CDog()
{
m_Age=1;
m_Weight=2;
printf("sonstruct instance\n");
}
CDog::~CDog()
{
}
int main(int argc,char*argv[])
{
CDog mydog;
printf("%d",mydog.m_Age);
return 0;
}
为什么printf头文件用iostream........
