我在dos命令里面输入cl 1.cpp总是提示错误是什么原因?(文件名为1.cpp)
提示是
fatal error C1034:iostream.h:no include path set
程序本身不错 下面是程序的代码,谢谢大侠
#include <iostream.h>
#include <stdio.h>
class ClassA
{
public:
int m_data1;
int m_data2;
void func1() { }
void func2() { }
virtual void vfunc1() { }
virtual void vfunc2() { }
};
class ClassB : public ClassA
{
public:
int m_data3;
void func2() { }
virtual void vfunc1() { }
};
class ClassC : public ClassB
{
public:
int m_data1;
int m_data4;
void func2() { }
virtual void vfunc1() { }
};
void main()
{
cout << sizeof(ClassA) << endl;
cout << sizeof(ClassB) << endl;
cout << sizeof(ClassC) << endl;
ClassA a;
ClassB b;
ClassC c;
b.m_data1 = 1;
b.m_data2 = 2;
b.m_data3 = 3;
c.m_data1 = 11;
c.m_data2 = 22;
c.m_data3 = 33;
c.m_data4 = 44;
c.ClassA::m_data1 = 111;
//cout <<"a.m_data1=" <<a.m_data1 << endl;
