Define the missing member function. use "this" to distinguish the local member from the parameter name.

#include
using namespace std;

class cableplan{
public:
void setnumdays(int numdays);
int getnumdays() const;
private:
int numdays;
};

// fixme: define setnumdays() member function, using "this" implicit parameter.
void cableplan: : setnumdays(int numdays) {

/* your solution goes here */

return;
}

int cableplan: : getnumdays() const {
return numdays;
}

int main() {
cableplan house1plan;

house1plan. setnumdays(30);
cout < < house1plan. getnumdays() < < endl;

return 0;
}
