In void print records 方法

私が試したこと：

forループで他の条件を作ってみました

for(int i=2;x != false;i++){ ... x=false;}

しかし、それはループするか、最新の最初の入力のみを記録しません

新しい試行を編集
1,1,1,1,1、次に2,2,2,2,2を入力してこのコードを試しました
レコードを検索すると両方を見つけることができますが、表示すると空白になり、printrecord のコードに問題があり、混乱しています….

while(head!=NULL){
for(int i=2;x != false;){
	gotoxy(0,i);
	cout<<head->studentid;
	gotoxy(12,i);
	cout<<head->fullname;
	gotoxy(30,i);
	cout<<head->gender;
	gotoxy(39,i);
	cout<<head->yearlevel;
	gotoxy(51,i);
	cout<<head->course;
	gotoxy(61,i);
	cout<<head->birthday;
	gotoxy(71,i);
	cout<<head->address;
	
	i++;
	
	head = head->next;
	
	if (head->next = NULL){
		head = NULL;
		x=false;
	}
}

cout <<"\n\n";
}
