How can I make a class duration to store time length? - c++

Question

I am trying to write a class with 3 attribute and some constructors and following methods: set (h, m, s), Double getHousrs () operator +
correctTime(). To change e.g 1:76:84 to 2:13:13
Current code
#include <iostream>
using namespace std;
class duration {
public:
duration(int h, int m, int s)
:hour (h), minutes (m), seconds (s);
{}
void printDate()
{
cout << hour<< ":" << minutes << ":" << seconds << endl;
}
double getHours() {
return hours;
}
double getSeconds() {
return seconds;
}
private:
int hour;
int minutes;
int seconds;
duration operator+(duration &obj)
{ }
};
int main()
{
duration obj;
return 0;
}

The solution to your problem would be to add the values together which can be most efficiently done like this I also fixed all the other errors you had in your class:
#include <iostream>
using namespace std;
class duration {
public:
duration(int h, int m, int s)
:hour (h), minute (m), second (s)
{}
void printDate()
{
cout << hour<< ":" << minute << ":" << second << endl;
}
double getHours() {
return hour;
}
double getSeconds() {
return second;
}
duration operator + (const duration& other)
{
duration temp(0, 0, 0);
temp.second = (other.second+second)%60;
temp.minute = ((other.second + second)/60 + other.minute + minute)%60;
temp.hour = ((other.minute+minute)/60 + other.hour + hour)%60;
return temp;
}
private:
int hour;
int minute;
int second;
};
int main()
{
duration obj(3, 5, 10);
duration obj2(4, 55, 40);
duration temp = obj + obj2;
temp.printDate();
return 0;
}
