{
	ch = get char;
	
	if (ch is an operand)
		add ch to postfix expression;
	if (ch is a '(')
		push (s, ch);
	if (ch is a ')')
	{
		pop (s);
		while (ch !='('))
		{
			add ch to postfix expression;
			pop (s);
		}
	}

	if (ch is an operator)
	{
		while (!isEmpty(s)&&(precedence(stackTop())>=precedence(ch)))
		{
			pop (s);
			add ch to postfix expression;
		}
		push (s, ch);
	}
}

while (stackTop() !='#')
{
	pop (s);
	add ch to postfix expression;

Erm what you want your program to do ?

Thats not the c++ code you are trying to run.
Its little language constructs plus a lot of algorithmic language. Hence, the syntax errors
Please read a beginner's book on c++
