Homework help needed please

[JulianV304]

I need help with my programming homework I been having problems
with for loops with arrays can someone give me examples the details
are located in the class tester.



snow data.h



#pragma once
#include <iostream>

#include <iomanip>

string date;
double depth;
public:
SnowData(string _date = "2000/01/01", double _inches = 0);
void print();
string getDate();
double getDepth();
void setDepth(double);
void setDate(string);
};
