struct - C++ program doesn't run correctly -

i have written note program. reads notes, keeps them , allows user delete, select or update note. it's compiling , running, doesn't run correctly.

i have struct:

struct list {     char title[101];     char text[501];     int cont;     struct list* next;  };typedef list list; 

and these functions:

list* insert (list *l, char ti[101], char te[501]) {     list* new = (list*) malloc(sizeof(list));     strcpy (new -> title, ti);     strcpy (new -> text, te);     new -> next = l;     new -> cont = id;     id++;     return (new); }  list* delete (list* l, int v) {    list *ant = null;    list *p = l;     while (p != null && p -> cont != v) {       ant = p;       p = p -> next;    }    if (p == null)       return l;    if (ant == null)       l = p -> next;    else         ant -> next = p -> next;    free(p);    return l; }  void print (list *l) {     list *p;     (p = l; p != null; p = p -> next){       cout << "\ntitle: " << p -> title << "\n";       cout << "text: " << p -> text <<  "\n";       cout << "code: " << p -> cont << "\n" << "\n";     } } 

on int main have inserted , printed couple of times , worked fine. when want delete note, doesn't delete nor error code. yesterday working fine, today when got test it, nothing works right. can't understand why working , stopped.

as requested, main program:

list* ini(){     return (null); }   int main() {         list *l;         char title[101];         char text[501];         char v;          list* l1 = ini();          cout << "\ntitle: ";         gets(title);         cout << "text: ";         gets(text);         l1 = insert (l1,title,text);          fflush(stdin);         cout << "\ntitle: ";         gets(title);         cout << "text: ";         gets(text);         l1 = insert (l1,title,text);          fflush(stdin);         cout << "\ntitle: ";         gets(title);         cout << "text: ";         gets(text);         l1 = insert (l1,title,text);          print(l1);          cout << "delete: ";         cin >> v;         l1 = delete(l1, v);          print(l1);          return(0);          } 

note: rewrote code not translations, delete valid function called deleteitem.

your immediate issue this:

char v; //... cin >> v; l1 = deleteitem(l1, v);  // <-- v char,  

but

list* deleteitem (list* l, int v) { 

you passing char variable deleteitem when should passing int. change type of v int.

what happening char being translated int. if enter 1, being sent 49, since ascii value of 1 49.

one of things c++ allows declare variables close point of use. if had declared v closer deleteitem function call, may have spotted mistake yourself.
