I need help adding to my code below, which is in C++ and it needs to read the string of symbols from a HTML source file (et.html) and have it print "legal" or "illegal" as the result.

int pop();
bool isEmpty();
int peek();
};
int Stack::peek(){
return a[top];
}
bool Stack::push(int x){
if (top >= MAX){
cout
return false;
