Checking for NULL pointer in C/C++ [closed]
...
In my experience, tests of the form if (ptr) or if (!ptr) are preferred. They do not depend on the definition of the symbol NULL. They do not expose the opportunity for the accidental assignment. And they are clear and succinct.
Edit: As Soa...

How do I determine if my python shell is executing in 32bit or 64bit?
...fffffff', True)
sys.maxsize was introduced in Python 2.6. If you need a test for older systems, this slightly more complicated test should work on all Python 2 and 3 releases:
$ python-32 -c 'import struct;print( 8 * struct.calcsize("P"))'
32
$ python-64 -c 'import struct;print( 8 * struct.calcs...
Difference between Inheritance and Composition
...r example :
class X implements R
{}
class Y implements R
{}
public class Test{
R r;
}
In Test class using r reference I can invoke methods of X class as well as Y class. This flexibility was never there in inheritance
3) Another great advantage : Unit testing
public class X {

How to check if an object is nullable?
... boxed, but you can with generics:
- so how about below. This is actually testing type T, but using the obj parameter purely for generic type inference (to make it easy to call) - it would work almost identically without the obj param, though.

{
if (obj =...
How to check if a map contains a key in Go?

test it by simple indexing.

}
if attended[person] { // will be false if person is not in the map
fmt.Println(person, "was at the meeting")

Any way to Invoke a private method?

Method concatString can be invoked as

String str = (String) genericInvokeMethod(t, "concatString", "Hello", "Mr.x");
