patulong sa mga master jan. bakit po same output lahat ng lumalabas sa mga inenter ko. tas hanggang 4 lang po ang kaya nyang node nag sstop working ung command line pag nag enter ng 5 node.

#include <iostream>
#include <cstdlib>
#include <iomanip>
#include <stdio.h>

using namespace std;

struct employee
{
string name;
string position;
int salary;
employee *next;
};

employee *head;

void callme()
{
employee *temp, *newnode;
string temp_name;
string temp_position;
int temp_salary;
int n;

head=(employee *)malloc(sizeof(employee));
if(head==NULL)
{
cout<<"No size of head"<<endl;
}

cout<<"Enter number of node";
cin>>n;
cout<<"Enter Name : ";
cin>>temp_name;
cout<<"Enter Salary : ";
cin>>temp_salary;
cout<<"Enter Position : ";
cin>>temp_position;

head->name=temp_name;
head->salary=temp_salary;
head->position=temp_position;
head->next= NULL;
temp=head;

for(int i=2 ; i<=n ; i++)
{
newnode=(employee *)malloc(sizeof(employee));
if(newnode == NULL)
{
cout<<"No size for new node"<<endl;
}
cout<<"Enter name : ";
cin>>temp_name;
cout<<"Enter Salary : ";
cin>>temp_salary;
cout<<"Enter Position : ";
cin>>temp_position;

newnode->name=temp_name;
newnode->salary=temp_salary;
newnode->position=temp_position;
newnode->next=NULL;
temp->next=newnode;
temp=temp->next;
}

cout<<"name\t\t\tPosition\t\t\tsalary\t\t\t"<<endl;
while(head != NULL)
{
cout<<temp_name<<"\t\t\t"<<temp_position<<"\t\t\t"<<temp_salary<<endl;
head=head->next;
}
while(newnode != NULL)
{
cout<<temp_name<<"\t\t\t"<<temp_position<<"\t\t\t"<<temp_salary<<endl;
newnode=newnode->next;
}

}

int main()
{
callme();
}

yung for loop mo try mong baguhin

I-rewrite mo yung code mo. Mainam na i-practice mo yung proper formatting. Tapos, i-embed mo sa code-blocks yung code mo para maayos tingnan.

To be honest, nahilo ko kababasa ng code mo. Eto mas, comprehensible:

Code:

#include <iostream>

struct Employee {
    std::string name;
    std::string position;
    int salary;
    Employee *next;
};

Employee *pHead = nullptr;
int num_employee{0};

Employee *get_data() {
    std::string name, position;
    int salary;
    std::cout << "\nEnter name: ";
    std::cin >> name;
    std::cout << "Enter position: ";
    std::cin >> position;
    std::cout << "Enter salary: ";
    std::cin >> salary;
    Employee *new_employee = new Employee;
    new_employee->name = name;
    new_employee->position = position;
    new_employee->salary = salary;
    new_employee->next = nullptr;
    return new_employee;
}

void add_employee(Employee *new_employee) {
    new_employee->next = pHead;
    pHead = new_employee;
}

int main(void) {
    std::cout << "\nEnter number of employee: " << std::flush;
    std::cin >> num_employee;
    Employee *new_employee = new Employee;
    for (int i=0; i<num_employee; i++) {
        add_employee(get_data());
        if (i==num_employee) {
            add_employee(nullptr);
        }
    }

    std::cout << std::endl;
    std::cout << "\nNow displaying the contents of Linked List..." << std::endl;
    for(Employee *iter=pHead; iter; iter=iter->next) {
        std::cout << "NAME: " << iter->name << std::endl;
        std::cout << "POSITION: " << iter->position << std::endl;
        std::cout << "SALARY: "  << iter->salary << std::endl << std::endl;
    }

    return 0;
}

C++:

for(int i=2 ; i<=n ; i++)
{
    //Statement here...
}

I wonder why did you initialized your int variable 'i' to 2? If you try to simulate that manually, that would only yields 4 loops, which can be illustrate as follows: (2<=5) = yes, (3<=5) = yes, (4<=5) = yes, (5<=5) = yes. I dont want to give you the exact advice but it's almost I am done telling you with the illustration I gave you. Hope it helped.

Ang ganda ng code ni sir oh. Simplified and well written with a good coding scheme practice.
