Question

I am having a problem with the following code. I need to search first the record then delete it:

It always delete the last record. Even if I want to delete the first any rcord in the middle

string NameForSearch1;

                     cout<<"Enter Your Friend's Name:      "<<endl;
                     cin>>NameForSearch1;

                     tempRec->namePerson=NameForSearch1;

                     if (tempRec==firstRec){//delete the head

                                      tempRec->next=firstRec;
                                      firstRec=tempRec->next;
                                      delete tempRec;
                                      DisplayRec();
                                      }

                     else if (tempRec->next==NULL ){//delete the last record

                                      tempRec2=firstRec->next;
                                      while(tempRec2->next!=tempRec){
                                            tempRec2 = tempRec2->next;
                                      }
                                      tempRec2->next=NULL;                                         
                                      delete tempRec;


                                      }
                     else {
                          //delete anyrecord
                                          tempRec2=firstRec->next;
                                          while(tempRec2->next!=tempRec){
                                                                         tempRec2 = tempRec2->next;
                                                                         }             
                                          tempRec2->next=tempRec->next;
                                          delete tempRec;

                                          }

After hours of debugging, I am finally able to get the right code:

string NameForSearch1;

                     cout<<"Enter Your Friend's Name:      "<<endl;
                     cin>>NameForSearch1;

                     tempRec=firstRec;

                     if (tempRec->namePerson==NameForSearch1){//delete the head

                                      firstRec=tempRec->next;
                                      delete tempRec;
                                      DisplayRec();
                                      }

                     else 
                     {
                          while (tempRec!=NULL && tempRec->namePerson!=NameForSearch1){
                                               tempRec2=tempRec;
                                               tempRec=tempRec->next;
                                       }

                                       if (tempRec==NULL)
                                       {
                                                         cout<<"NO RECORD FOUND";
                                       }
                                       else if (tempRec->namePerson==NameForSearch1)
                                       {
                                            tempRec2->next=tempRec->next;
                                            delete tempRec;     
                                        }
                       }
