C++程序設置並獲得類

Question

某處我出錯了什麼似乎是問題？但這正是我想要做的：我想創建一個Employee類，它包含這些數據成員的名字（類型字符串），姓氏（類型字符串）和月薪（類型爲int，也是一個構造函數，用於初始化三個數據成員，爲每個數據成員提供一個集合和一個get函數，如果月薪不正，我想將其設置爲0，則創建兩個Employee對象並顯示每個對象的年薪，併爲每個Employee分配20％提高並顯示每個員工的年薪再次

#include <iostream> 
#include <string> 
using namespace std; 

class Employee { 

public: 

Employee(string f ,string l ,int m){ 
setFName(f) ; 
setLName(l) ; 
setMSalary(m) ; 
} 

void setFName(string f){ 
fName = f ; 
} 

string getFName(){ 
return fName ; 
} 

void setLName(string l){ 
lName = l ; 
} 

string getLName(){ 
return lName ; 
} 

void setMSalary(int m){ 
if (m <0){ 
mSalary = 0 ; 
    } 
else { 
mSalary = m ; 
    } 
} 

intgetMSalary(){ 
returnmSalary ; 
} 

intySalary(){ 
return12 * mSalary ; 
} 

intraise(){ 
return (0.10 * ySalary()) + ySalary() ; 
} 

private : 

string fName ; 
string lName ; 
int mSalary ; 
}; 



int main(){ 

Employeeem1("SARA" , "SALEH" , 5000); 
Employeeem2("Bayan" , "Khaled" , 8000) ; 

cout<<"The yearly salary of first employee is "<< em1.ySalary() <<endl ; 
cout<<"The yearly salary of second employee is "<< em2.ySalary()<<endl ; 

cout<<"\nThe yearly salary of first employee is after raising "<<em1.raise()<<endl ; 

cout<<"The yearly salary of second employee is after raising "<<em2.raise() <<endl ; 
} 

也

#include <iostream> 
#include <string> 
using namespace std ; 

class Employee { 

public: 

Employee(string f ,string l ,int m){ 
setFName(f) ; 
setLName(l) ; 
setMSalary(m) ; 
} 

void setFName(string f){ 
fName = f ; 
} 

string getFName(){ 
return fName ; 
} 

void setLName(string l){ 
lName = l ; 
} 

string getLName(){ 
return lName ; 
} 

void setMSalary(int m){ 
if (m <0){ 
mSalary = 0 ; 
    } 
else { 
mSalary = m ; 
    } 
} 

int getMSalary(){ 
return mSalary ; 
} 

private : 

string fName ; 
string lName ; 
intmSalary ; 
}; 



int main(){ 

Employeeem1("SARA" , "SALEH" , 5000); 
Employeeem2("Bayan" , "Khaled" , 8000) ; 
int raise1 , raise2 ; 

cout<<"The yearly salary of first employee is "<< em1.getMSalary()*12<<endl ; 

cout<<"The yearly salary of second employee is "<< em2.getMSalary() *12<<endl ; 

raise1 = (0.20 * em1.getMSalary()) + em1.getMSalary() ; 
raise2 = (0.20 * em2.getMSalary()) + em2.getMSalary() ; 

cout<<"\nThe yearly salary of first employee is after raising "<< raise1 * 12<<endl ; 

cout<<"The yearly salary of second employee is after raising "<< raise*12<<endl ; 
} 

我得到這些錯誤

這是第二個版本的語法更正。您只有輕微的空間相關問題...請參閱內嵌評論
