How do you initialize a private static data member in C++?
#include <iostream>
using namespace std;
class MyClass{
private:
static int st_var;
public:
MyClass(){
st_var++; //increase the value of st_var when new object is created
}
static int getStaticVar() {
return st_var;
}
};
// don't forget the type of the variable you want to initialize
int MyClass::st_var = 0; //initializing the static int
main() {
MyClass ob1, ob2, ob3; //three objects are created
cout << "Number of objects: " << MyClass::getStaticVar();
}
