Default [TANYA]yg bisa bhs C "single linked list" tolongin ane dong?

nih gan=



//STACK USING SINGLE LINKED LIST

#include

#include



struct data

{

int angka;

struct data *next;

}*head,*curr,*tail;



void push(int angka)

{

curr=(struct data*)malloc(sizeof(struct data));

curr->angka=angka;



if(head==NULL)

{

head=tail=curr;

}

else

{

tail->next=curr;

tail=curr;

}

tail->next=NULL;



printf("Push berhasil.");

getchar();

}



void pop()

{

curr=head;

if(head==NULL)

{

printf("Data masih kosong");

}

else

{

if(head==tail)

{

free(head);

head=NULL;

}

else

{

head=head->next;

free(curr);

}

}

}



void cetak()

{

curr=head;



while(curr)

{

printf("%d",curr->angka);

curr=curr->next;

}

}



void main()

{

int choose,angka;



do{

system("cls");

cetak();



printf("\n\nMenu:\n");

printf("1. Push.\n");

printf("2. Pop.\n");

printf("3. Exit.\n");

printf("Pilih(1-3): ");

do{

scanf("%d",&choose);

fflush(stdin);

}while(choose3);



switch (choose)

{

case 1:

printf("\nAngka berapa yang ingin dipush: ");

scanf("%d",&angka);

fflush(stdin);

push(angka);

break;

case 2:

pop();

break;

}

}while(choose!=3);



printf("\n\n\nTERIMAKASIH\n");

printf("%c%c%c%c%c%c%c%c%c%c%c",219,219,219,219,21 9,219,219,219,219,219);



getchar();

}



pertanyaan ane, kenapa yang ane bold harus ada? padahal kan udah di free, kenapa perlu di NULLin. kan datanya cuma satu.



(ini bukan tugas, sekedar ingin tau saja)
