Answer 1

you cannot declare variable inside an if-else statement:

int pop(){
int result;
if(stack[top]==empty)
return stack_empty;
else
result=stack[top];
top--;
return (result);
}

Answer 2

stack[top] == empty will compare the stack element at index 'top' with empty (instead of the stack element counter).

"you cannot declare variable inside an if-else statement"

In this context 'result' cannot be declared in the if-else statement because it's returned by the function. I'd personally drop the temp variable (and maybe even reduce it down to a one-liner).

return (top > empty) ? stack[--top] : stack_empty;
