   {
        int info;
        node *next;
   };

     node* head=NULL;
     node* temp=NULL;
     node* temp1=NULL;
     head=new node;
     head->next=NULL;
     int c;
     cout<<"1--->insert."<<endl<<"2--->delete."<<endl<<"3--->print."<<endl<<"4--->Exit."<<endl;
     cout<<"Enter the choice --";
     cin>>c;

          {
             int x;
            cout<<"Enter the data to be insterted __ ";
             cin>>x;
             if(head->next==NULL)
              head->info=x;
             else
               {
                temp=head;
                while(temp->next!=NULL)
                 temp=temp->next;
                if(temp->next==NULL)
                 {
                  temp1=new node;
               temp1->info=x;
                  temp->next=temp1;
                  temp1->next=NULL;
                 }

Maybe you want that:

#include <iostream>
using namespace std;

struct node
{
   int info;
   node *next;
};

void insert(node*& head);
void print(node* head);
void deleteAll(node* head);

int main()
{
   
    node* head= NULL;
   
    while (true)
    {
        int c;
        cout<<endl<<"1--->insert."<<endl<<"2--->delete."<<endl<<"3--->print."<<endl<<"4--->Exit."<<endl;
        cout<<"Enter the choice --";
        cin>>c;
       
        switch(c)
        {
        case 1:
            insert(head);
            break;
            //     case 2:del();break;
        case 3:
            print(head);
            break;
        case 4:
            deleteAll(head);
            return 0;
        default:
            cout<<"Entered wrong choice"<<endl;
            break;
        }
    }
    return 1;
}


void insert(node*& head)
{  
    node* temp;
    node* temp1;
    int x;
    cout<<"Enter the data to be inserted __ ";
    cin>>x;
    if(head==NULL)
    {
        head = new node;
        head->next = NULL;
        head->info = x;
        return;
    }
    temp=head;
    while(temp->next!=NULL)
        temp=temp->next;
    temp1=new node;
    temp1->info=x;
    temp->next=temp1;
    temp1->next=NULL;
}

void print(node* head)
{
    if(head==NULL)
        cout<<"No elements to display";
    else
    {
        node* temp=head;
        do
        {
            cout<<temp->info<<"->";
            temp=temp->next;
        }
        while(temp !=NULL);
    }
}


void deleteAll(node* head)
{
    node* temp = head;
    node* temp1;
   
    while (temp != NULL)
    {
        temp1 = temp->next;
        delete temp;
        temp = temp1;
    }
}
