I'm beginner with c++ and want some help
Create Class CSalary with private member variables
string m_strProfession
double m_dSalary
Constructors:Default,Copy,Explicit
Functions:
1/string GetProf(void),double GetSalary(void)
2/SetProf(const string val),SetSalary(const double val)
3/Output(ostream&) and Input(istram&)
4/Operators:<<,>>,=,==,<,double operator*(const CSalary&obj)
Create Class CCalcCorr with private member variables:
vector<CSalary>m_vCity1//data for city 1
vector<CSalary>m_vCity2//data for city 2
double m_dCorr//correlation coefficient
Constructors:
Explicit by data filenames string fNmae1,string fName2
CCalcCorr(const string& strFileName1,const string& strFileName2)
<profession> <salary>
Web Developer 5000
Functions:/I want help for these functions/
Colculate correlation coefficient btw 2 vectors in m_dCorr and return it in dCorr.Return false if can't calculate
Formulas:
Corr=SUMxy/sqrt(SUMxxSUMyy) where :
SUMxx = SUM(City1City1)-SUM(City1)SUM(City1)/n
SUMxy = SUM(City1City2)-SUM(City1)SUM(City2)/n
SUMyy = SUM(City2'City2)-SUM(City2)SUM(City2)/n where:
City1 - current value m_dSalary from m_vCityl
City2 - current value m_dSalary from m_vCity2
n- size of m_vCityl and m_vCity2
-return correlation
-change data for profession/write dCity1,dCity2/
-read data/return dCity1,dCity2/
-void WriteTo()-write stream data
<Prof,Salary1(m_vCity1),Salary2(m_vCity2)>
-input/output operators
Main function-read data from input files,create CCalcCorr,testing functions
here is my code and i don't know how to continue and if code is right?
