Constructors in C++

Question

Why I face this Error, Again and again, I tried to solve out but I didn't is anyone help me with this:------

#include<iostream>
#include<string.h>
#include<conio.h>
using namespace std;
class employees{
private:
int emp_no;
char emp_name[20];
char emp_address[30];
int no_of_dependents;
public:
employees(){emp_no=no_of_dependents=0;strcpy(emp_name,0);strcpy(emp_address,0);}
void setEmp_no(int t){emp_no=t;
}
void setEmp_name(string a){a=emp_name;
}
void setEmp_address(string a){a=emp_address;
}
void setNo_of_dependents(int s){no_of_dependents=s;
}
void input(){cin>>emp_no>>emp_name>>emp_address>>no_of_dependents;
}
void getEmployee_no(){emp_no;}
string getEmployee_name(){return emp_name;}
string getEmployee_address(){return emp_address;}
void getNo_of_dependents(){no_of_dependents;}
void display(){cout<<emp_no<<emp_name<<emp_address<<no_of_dependents;}
};
int main()
{
employees empno,ename[20],eadd[30],nod;
empno.input();
ename.input();
eadd.input();
nod.input();
empno.display();
ename.display();
eadd.display();
nod.display();
getch();
}

Answer 1

Manish Jha Where are you compiling the code? On Sololearn or on a PC?

Also, I see some logical errors which I will mention below, and maybe correcting those will help you :

0) In setEmp_Name you are accepting an std::string (a in this case), but in the function body, you reassign a with the value of emp_name, and not the other way around. That may be a logical error. I think you should do : strcpy(a.c_str(),emp_name); and include the header <string> for std::string.

1) In some getter functions, you specified the return type as void, but I think they are expected to return the appropriate values that you have mentioned inside the same.
That is also a logical_error.

Answer 2

yes, I compiled this program in codeblocks but I face the problem with strings in the constructor.
