c++ - Declaring two variable in a conditional? -


Can I declare two conditionally two variables in C? The compiler gave an error, but I think I should get the opinion: 

  int main () {double D1 = 0; If ((double D2 = D1) || (double D3 = 10)) COAT & LT; & Lt; "Wow" & lt; & Lt; Endl; Return 0;

You can do this for only one variable 

  If (double D2 = D1) COAT & lt; & Lt; "Wow" & lt; & Lt; Endl; And if (double D3 = 10) COAT & LT; & Lt; "Wow" & lt; & Lt; Endl;

But I will declare them out of terms. If you are scared of scope, then you can always limit it: 

  {double D2 = D1; Double D3 = 10; If (D2 || D3) COAT & LT; & Lt; "Wow" & lt; & Lt; Endl; }

Of course, it evaluates the second initiator, even if D2 evaluates on the right but I think it is not important
