What is the initial value for a numeric field ??

Question

Can someone tell me what the INITIAL VALUE FOR A NUMERIC FIELD is ?? Thank you
Rod.

Answer 1

Using the following...
   class MyClass
     int myvar1;  // Default initial value
     int myvar2 = 3;  // Default initial value and default value
     MyOtherClass myclass1; // Default initial value
     void doit()
       int mylocal1;  // No value
       MyOtherClass myclass2; // No value
All number member variables, like myvar1 start off with andefault initial value which is zero. For booleans this is false. Object reference variables, like myclass1, have a null value.
All local numeric variables are considered undefined. So mylocal1 and myclass2 are undefined. Before you can use them you must explicitly provide a value.
Finally note that myvar2 will have two values during class instantiation. Initially it will have a value of zero. Sometime later it will have the value of 3. (When that happens is very definitely outside the scope of what this forum covers. If you want to know then ask in the advanced forum.)
