The this Pointer
#include <iostream>
using namespace std;
class Power {
double b;
int e;
double val;
public:
Power(double base, int exp);
double getPower() {
return val;
}
};
Power::Power(double base, int exp)
{
b = base;
e = exp;
val = 1;
if(exp==0)
return;
for( ; exp>0; exp--)
val = val * b;
}
int main()
{
Power x(4.0, 2), y(2.5, 1), z(5.7, 0);
cout << x.getPower() << " ";
cout << y.getPower() << " ";
cout << z.getPower() << "\n";
return 0;
}
Use "this" pointer.
#include <iostream>
using namespace std;
class myclass {
int a, b;
public:
myclass(int n, int m) {
this->a = n;
this->b = m;
}
int add() {
return this->a + this->b;
}
void show();
};
void myclass::show()
{
int t;
t = this->add(); // call member function
cout << t << endl;
}
int main()
{
myclass ob(10, 14);
ob.show();
return 0;
}
