What is the output of the following program?

Question

int a=1; b=0;
b=a
cout<<++a*b++;

Answer 1

* int a=1,b=0;
b=a; (Missed ;)

And the output is 2.

Answer 2

Well first of all, for the:
int a=2; b=0;
You seperate each new variable with the same type by a comma instead
int =2, b=0;
Also the statement b=a needs a semicolon
b=a;
And then your code will work
It will like like this at the end:

#include <iostream>
using namespace std;

int main() {
int a=1, b=0;
b=a;
cout<<++a*b++;
}

The answer will be 2 because you set b to a, which is 1, so both a and b are 1. Then you perfrmed an equation using "++." Before the variable means add one in the equation, after the variable means don't add one till after the equation, so the equation becimes 1*2 which is equal to 2. Hope this helped.
