Answer : Please note that there are different interpretations of the "association" definitions. My views below are heavily based on what you would read in Oracle Certification books and study guides. Temporary association A usage inside a method , its signature or as a return value. It's not really a reference to a specific object. Example: I park my Car in a Garage. Composition association A so-called " STRONG relationship ": The instantiation of the linked object is often hard coded inside the constructor of the object. It cannot be set from outside the object. (Composition cannot be a many-to-many relationship.) Example: A House is composed of Stones. Direct association This is a " WEAK relationships ". The objects can live independent and there are usually setters or other ways to inject the dependent objects. Example: A Car can have Passengers. Aggregation association Very similar to a Direct as

Answer : OS X comes with DigitalColor Meter: Applications > Utilities > DigitalColor Meter.app It has many options and preferences. command+shift+c will copy the color under the cursor to the clipboard in many different formats. The Mac OS X color picker is extensible. Use Hex Color Picker to add a tab that provides you the configured color in hexadecimal RGB. Just run e.g. TextEdit and press Cmd-Shift-C to open the color picker, or run your standalone program. An even more versatile color picker is Developer Color Picker with many different output formats, one of which is hexadecimal. This is easily done with AppleScript. A complete working example of code is available here.

Answer : There is no implicit this-> in Python like you have in C/C++ etc. You have to call it on self . class Foo: def __bar(self, arg): #do something def baz(self, arg): self.__bar(arg) These methods are not really private though. When you start a method name with two underscores Python does some name mangling to make it "private" and that's all it does, it does not enforce anything like other languages do. If you define __bar on Foo , it is still accesible from outside of the object through Foo._Foo__bar . E.g., one can do this: f = Foo() f._Foo__bar('a') This explains the "odd" identifier in the error message you got as well. You can find it here in the docs. __bar is "private" (in the sense that its name has been mangled), but it's still a method of Foo , so you have to reference it via self and pass self to it. Just calling it with a bare __bar() won't work; you have to call i

Example: c++ program to find gcd of 3 numbers #include<stdio.h> int main ( ) { int a , b , c , hcf , st ; printf ( "Enter three numbers : " ) ; scanf ( "%d,%d,%d" , & a , & b , & c ) ; st = a < b? ( a < c?a : c ) : ( b < c?b : c ) ; for ( hcf = st ; hcf >= 1 ; hcf - - ) { if ( a % hcf == 0 & & b % hcf == 0 & & c % hcf == 0 ) break ; } printf ( "%d" , hcf ) ; return 0 ; }

Example: how to dynamically allocate array size in c // declare a pointer variable to point to allocated heap space int * p_array ; double * d_array ; // call malloc to allocate that appropriate number of bytes for the array p_array = ( int * ) malloc ( sizeof ( int ) * 50 ) ; // allocate 50 ints d_array = ( int * ) malloc ( sizeof ( double ) * 100 ) ; // allocate 100 doubles // use [] notation to access array buckets // (THIS IS THE PREFERED WAY TO DO IT) for ( i = 0 ; i < 50 ; i ++ ) { p_array [ i ] = 0 ; } // you can use pointer arithmetic (but in general don't) double * dptr = d_array ; // the value of d_array is equivalent to &(d_array[0]) for ( i = 0 ; i < 50 ; i ++ ) { * dptr = 0 ; dptr ++ ; }
