How do I modify the  attached C++ class to handle unitialized variables?  It is a symbol table and I want it to display an error such as "Uninitialized Variable y" for expressions like:
(x/y), x = 1;

#include <string>
#include <vector>
using namespace std;

#include "symboltable.h"

void SymbolTable::insert(string variable, double value)
{
    const Symbol& symbol = Symbol(variable, value);
    elements.push_back(symbol);
}

double SymbolTable::lookUp(string variable) const
{
    for (int i = 0; i < elements.size(); i++)
		if (elements[i].variable == variable)
			return elements[i].value;
    return -1;
}
