I have a scenario in which i am not able to create a class object inside another class. The scenario is as follows:

class base
{
public:
base();
~base();
int getbase(void){return baseVar;}
void setbase(int arg){baseVar = arg;}
private:
int baseVar;
};

class derived1 : public base
{
public:
derived1();
~derived1();
int getbase(void);
void setbase(int arg);
private:
int derVar1;
};

class derived2 : public base
{
public:
derived2();
~derived2();
int getbase(void);
void setbase(int arg);
private:
int derVar2;
};

class container
{
public:
container();
~container();

derived1 derObj1;
derived2 derObj2;

private:
int containerVar;
};

class usage
{
public:
usage();
~usage();
private:
container containerObj; // compilation error
int usegeVar;
};

compilation error is : error C2146: syntax error : missing ';' before identifier 'containerObj' error C4430: missing type specifier - int assumed. Note: C++ does not support default-int error C4430: missing type specifier - int assumed. Note: C++ does not support default-int i am using vc++

I request some one how to rectify this compilation error? Thanks In advance.

Have you included the header file defining class container in file which defines class usage? The error means that compiler cannot see defintion of type container. - Alok Save
As we used to say in the Air Force: CND (could not duplicate). It compiled with no errors with both VC++10 and gcc 4.7. - Jerry Coffin

Copy an pasted your code on an empty VisualC++ 2k8 project and is OK!
