Question

//linked list inserting a node in the begginging;

#include <iostream>
using namespace std;

struct node
{
char esm[30];
node* next;

};

void print(node* head)
{
for (; head; head = head->next)

cout << head->esm << endl;
}
}

node* ezafekardan_niro(node* head)
{
node* niro = new node;
niro->next = NULL;
cout << "esm"<<endl;
cin >> niro->esm;
niro->next = head;

return head;

}

node *hazf_niro(node *head)

int main()

node* head = NULL;

unsigned short tedad_karkonan = 0;


cin >> tedad_karkonan;

for (unsigned short i = 0; i < tedad_karkonan; i++)

//define struct student by name by linked list
struct student
{
    char name[20];
    int age;
    struct student *next;
};
//define function to add student
void add_student(struct student **head, char name[], int age)
{
    struct student *new_student = (struct student *)malloc(sizeof(struct student));
    strcpy(new_student->name, name);
    new_student->age = age;
    new_student->next = *head;
    *head = new_student;
}
//define function to delete student
void delete_student(struct student **head, char name[])
{
    struct student *temp = *head;
    struct student *prev = NULL;
    while (temp != NULL)
    {
        if (strcmp(temp->name, name) == 0)
        {
            if (prev == NULL)
            {
                *head = temp->next;

            break;
