#include"iostream"
class CMessage
{
public:int a;
CMessage(){}
~CMessage(){}
};
void Testing(CMessage *f_pMessage)//l_pMessage is output parameter
{
f_pMessage = new CMessage();
f_pMessage->a = 1;
}
int main()
{
CMessage *l_pMessage =NULL;
Testing(l_pMessage);
std::cout<<l_pMessage->a;//getting l_pMessage = NULL;
return 0;
}
when i called testing then inside testing f_pMessage is getting intialize but as ssoon as
i after excuting testing function it should be store in l_Pmessage but it is showing NULL.confussed.....
