three way comparison operator c++

//Since C++20
	lhs <=> rhs  
The expression returns an object that
- compares <0 if lhs < rhs
- compares >0 if lhs > rhs
- compares ==0 if lhs and rhs are equal/equivalent.

x += c++

int main ()
{
  int a, b=3;
  a = b;
  a+=2;             // equivalent to a=a+2
  cout << a;
}
