void function returns false if throws

[Chuvi-w]

public class CanThrow { public static void WillThrow(int a) { if (a<15){throw "a<15";} Console.WriteLine(a); } }

compiles into void CanThrow_WillThrow(int a) { if (a < 15) { return false; } printf("%d\n", a); }

This was invalid Ć. The method should have been marked with throws, like in Java:

public class CanThrow { public static void WillThrow(int a) throws { if (a<15){throw "a<15";} Console.WriteLine(a); } }

I've added the missing error message.

C doesn't support exceptions, so they are emulated by magic return values, here false for an exception.

Thank you!

void funtion must not return anything.

There were bugs both in your code and cito. Please pull cito and rebuild.
