59.2 practice charge!

Question

Can anyone fix it?

Selection Operator

You are creating a program to manage smartphones. The given code declares a Phone class, with its constructor and two methods: use() and getCharge().
A Phone object is declared in main. Complete the code to call the getCharge() method using the correct selection operator.
You can call a member function directly on the object, or using the pointer.

#include <iostream>
using namespace std;

class Phone
{
public:
int charge;
Phone() {
charge = 100;
}
void use() {
charge -=10;
}
void getCharge() {
cout << charge;
}
};

int main() {
Phone p;
p.use();
Phone *ptr = &p;

//call the getCharge() method on ptr

}

Answer 1

#include <iostream>
using namespace std;

class Phone
{
public:
int charge;
Phone() {
charge = 100;
}
void use() {
charge -=10;
}
void getCharge() {
cout << charge;
}
};

int main() {
Phone p;
p.use();
Phone *ptr = &p;

//call the getCharge() method on ptr
ptr -> getCharge();
}

Good Luck
