#include<iostream>
using namespace std;
int main(void){
int $;
$=1000;
cout<<$;
return 0;}
when I run this code it runs successfully but according to language it should give error on using $ as identifier so can anyone help me in better understanding this?But according to many books and tutorials $ cannot be used as identifier and the editor is showing error for @ and % but not for $ why so? please explain
