What's the output of this program?

Question

#include<iostream>
#include<stdio.h>
using namespace std;
int main()
{
int num1=5;
int num2=3;
int num3=2;
num1=num2++;
num2=--num3;
cout<<num1<<num2<<num3;
return 0;
}

Answer 1

Error, because <iostream.h> should be <iostream>.

If that is fixed, the output would be

311
