Question

"Function does not take 0 arguments". I keep getting this error for my last line of code: cout << "First Name: " << employee1.getfirstName() << endl;

I do not understand why. I am trying to put the name "Mike" into the firstName string. Why is my constructor not working? In main it should be set to string firstName, string lastName, int salary. Yet nothing is being put into the string.

#include<iostream>
#include<string>

using namespace std;

class Employee {
   int salary;
   string firstName;
   string lastName;
public:
   Employee(string firstName, string lastName, int salary)
   {
       setfirstName(firstName);
       setlastName(lastName);
       setsalary(salary);
   }

   void setfirstName(string name1) {
       firstName = name1;
   }

   string getfirstName(string name1) {
       return firstName;
   }

   void setlastName(string name2) {
       lastName = name2;
   }

   string getlastName(string name2) {
       return lastName;
   }

   int setsalary(int b) {
       if (salary < 0) {
           salary = 0;
       }
       else
       salary = b;
   }

   int getsalary() {
       return salary*12;
   }

};

void main()
{
   Employee employee1("Mike", "Johnson", 500);

       cout << "First Name: " << employee1.getfirstName() << endl;

SOURCE CODE

#include<iostream>
#include<string>

using namespace std;

class Employee {
int salary;
string firstName;
string lastName;
public:
Employee(string firstName, string lastName, int salary)
{
setfirstName(firstName);
setlastName(lastName);
setsalary(salary);
}

void setfirstName(string name1) {
firstName = name1;
}

string getfirstName() {
return firstName;
}

void setlastName(string name2) {
lastName = name2;
}

string getlastName() {
return lastName;
}

int setsalary(int b) {
if (salary < 0) {
salary = 0;
}
else
salary = b;
}

int getsalary() {
return salary*12;
}

};

int main()
{
Employee employee1("Mike", "Johnson", 500);
cout << "First Name: " << employee1.getfirstName() << endl;
   return 0;
}

OUTPUT SCREENSHOT

Here you in the function

string getfirstName(string name1) {
       return firstName;
   }

you pass one argument string no need to pass that. This gives you error otherwise all good, Constructor works fine .

please give a upvote if u feel helpful.
