AOA
Dear fellows i have code in which i uses linked list.when i compile that program the compiled file run but not work.
I write this code in Dev c++.
#include <iostream.h>
#include <string.h>
#include <stdlib.h>
using namespace std;
class Node
{
public:
int value;
string Name;
Node * next;
Node(int a, string b)
{
this->value=a;
this->Name=b;
this->next=NULL;
}
};
Node *Head;
void addNod(int value, string name)
{
Node *p;
if(Head==NULL)
{
Head = new Node(value,name);
}
else
{
p=Head;
while(p->next!=NULL)
{
p=p->next;
}
p->next = new Node(value,name);
}
}
void SearchThis(string a)
{
while(Head->Name!=a)
{
Head=Head->next;
}
cout<<"found: "<< Head->value<<" "<<Head->Name<<endl;
}
void DeleteFunction(string InfoToDelet)
{
Node *Current, *NextCurrent;
if(Head->Name==InfoToDelete)
{
Current=Head;
Head=Head->next;
delete Current;
}
else
{
Current=Head;
while(Current!=NULL && Current->Name!=InforamtionToDelete)
{
NextCurrent = Current;
Current = Current->next;
}
if(Current)
{
NextCurrent->next = Current->next;
delete Current;
}
}
}
void PrintList()
{
Node *Print;
Print = Head;
while(Print!=0)
{
cout<<Print->value<<" "<<Print->Name<<endl;
Print=Print->next;
}
}
int main()
{
int choice;
cout<<"1- Enter student information"<<endl;
cout<<"2- Search student by ID"<<endl;
cout<<"3- Search student by Name"<<endl;
cout<<"4- Delete student information"<<endl;
cout<<"5- Print all students"<<endl;
cout<<"6- Quit"<<endl;
int ID;
string na;
while(choice!=6)
{
cout<<"\n\n \t\tEnter ur choice \n "<<endl;
cin>>choice;
if(choice==1)
{
cout<<"Enter ID ";
cin>>ID;
cout<<"Enter name ";
cin>> na;
addNod(ID,na);
}
else if(choice==2)
{
cout<<"Search Student by ID "<<endl;
cin>>ID;
SearchThis(ID);
}
else if(choice==3)
{
cout<<"Search student by name "<<endl;
cin>>na;
Search This(na)
}
else if(choice==4)
{
cout<<"Delete Student Information "<<endl;
cin>>DeleteFunction(Information);
DeleteThis(Information);
}
else if(choice==5){
cout<<"Print All Students "<<endl;
PrintList();
}
else
{
return 0;
}
}
system("pause");
