Help with a stack

I keep getting errors in my code and I can't seem to fix it. Any Idea what it could be?

Code:

#include<iostream>
using namespace std;

class stack{
private:
  int stackArray[3];
  int top;
  int size;
public:
  void push(int x);
  int pop();
  int showSize();
  void showElements();
  stack();
  ~stack();
};

stack::stack(){
  
  top = -1;
  size = 0;
  
}

stack::~stack(){
}

void stack::push(int x){
  if(size < 3}{
    top++;
    stackArray[size] = x;
    size++;
  }
}

int stack::pop(){
  int x = stackArray[top];
  top--;
  size--;
  return x;
}

int stack::showSize(){
  return size;
}

void stack::showElements(){
  
  for(int i = top; i > -1; i--){
    cout<<stackArray[i]<<endl;
  }
}


int main(){
  
  int val;
  stack s;
  s.push(5);
  s.push(4);
  s.push(3);
  cout<<"Size: "<<s.showSize()<<endl;
  cout<<"Elements Pushed: ";
  s.showElements();
  
  val = s.pop();
  s.pop();
  s.pop();
  cout<<"Last element Popped"<<val<<endl;
  s.showElements();
  
  
  return 0;
}

How does it not work?

I get these errors..

In member function `void stack:ush(int)':
onetwo.cpp:29: error: parse error before `}' token
onetwo.cpp: At global scope:
onetwo.cpp:31: error: `size' was not declared in this scope
onetwo.cpp:31: error: ISO C++ forbids declaration of `stackArray' with no type
onetwo.cpp:31: error: `x' was not declared in this scope
onetwo.cpp:31: error: assignment (not initialization) in declaration
onetwo.cpp:32: error: syntax error before `++' token

Code:

if(size < 3}{

should be:

Code:

if(size < 3){

Note the } versus )

wow thanks a bunch..i couldn't find that tiny little error!!!!
