Hello!
I'm working on this linked list project where I'm supposed to save the employee data in a linked list and apply some operations.
and I am new with c++ so I'll show you my code and please help me with it.
my questions are:
1- whenever I enter a full name the program keeps going in an infinite loop! i used getline() method and still its not working. but if I enterd just the first name it works fine.
2- I don't know how I can display or find the employee information if I used the methods I create it gives me random data.
my code:
Main:
#include<iostream>
#include<string>
#include <fstream>
#include "EmployeeList.cpp"
using namespace std;
int main(){
string name;
int choice, id;
double Salary;
EmployeeList* employee = new EmployeeList();
cout<<"***********************************************"<<endl;
cout<<"**********EMPLOYEE MANAGEMENT SYSTEM***********"<<endl;
cout<<"***********************************************\n\n"<<endl;
do{
cout<<" 1--->Press 1 to INSERT EMPLOYMENT:"<<endl;
cout<<" 2--->Press 2 to FIND EMPLOYMENT INFO ID:"<<endl;
cout<<" 3--->Press 3 to DELETE EMPLOYMENT ID:"<<endl;
cout<<" 4--->Press 4 to SEARCH HIGHEST SALARY:"<<endl;
cout<<" 5--->Press 5 to DISPLAY ALL EMOLYMENTS:"<<endl;
cout<<" 6--->Press 6 to REVERSE DISPLAY ALL EMPLOYMENTS:"<<endl;
cout<<" 7--->Press 7 to EXIT:"<<endl;
cout<<"\n Enter Your Choice: ";
cin>>choice;
switch(choice){
case 1:
cout<<endl;
cout<<"Enter name : ";
getline(cin,name);
cout<<"Enter ID : ";
cin>>id;
cout<<"Enter Salary : ";
cin>>Salary;
cout<<endl;
employee ->INSERTEMPLOYMENT(name,id,Salary);
break;
case 2:
cout<<endl;
cout<<"Enter ID : ";
cin>>id;
cout<<endl;
employee->FINDEMPLOYMENTINFOID(id);
break;
case 3:
cout<<endl;
cout<<"Employee ID : ";
cin>>id;
cout<<endl;
employee-> DELETEEMPLOYMENTID(id);
break;
case 4:
cout<<endl;
employee->SEARCHHIGHESTSALARY();
break;
case 5:
cout<<endl;
employee->DISPLAYALLEMPLOYMENTS();
break;
case 6:
cout<<endl;
employee->REVERSEDISPLAYALLEMPLOYMENTS(employee->getHead());
break;
case 7:
exit(0);
default:
cout<<"Invalid choice."<<endl;
break;
}
} while (true);
return 0;
