s.top=1;


int push()
{
	int num;
	if(s.top==(5-1))
	{
		cout<<"Stack is full"<<endl;
		return 0;
	}
	else
	{
		cout<<"Enter Number";
		cin>>num;

s.top=1; is a statement, it has to go in a function.

or the constructor... which is a function ;)

struct stack 
{
        stack()
        {
             top = 1;
        }

	int stk[5];
	int top;
};
