OK, I've decided to do it. To leave the elegance of Objective-C and have a closer look at C++. After all, isn't everyone doing oF these days?

Here a recapitulation of usesful C and some quick notes on C++ peculiarities - sorry - features: (That might be a good place to start.)

Initialisation int a = 1; // standard c way int b(1); // same

Defined constants

define PI 3.1415927 // faster than var

Declared constants const int c = 100 // immutable

Assignment = can also be used as rvalue a = 1 + (b = 2);

same as: b = 2; a = 1 + b;

Comma operator a = (b=3, b+2); // a = 5

When the set of expressions has to be evaluated for a value, only the rightmost expression is considered

Type casting int i, j; float f = 1.234; i = (int) f; j = int (f);

sizeof() One parameter, either a type or a variable and returns the size in bytes.

a = sizeof (char);

Will become important with arrays.
