Exercises, examples and other material relating to training module C235. This topic is presented on public courses Learning to program in C++, C++ for C Programmers, C and C++ Programming

The C++ streams library and output formatters provide you with an Object Oriented approach to user and file interaction. You can define an object's behaviour - which is much more efficient than having to format your output every single time.

3390	Printing objects in C++ Overloading operators with methods is a great way of providing a shorthand using the operator syntax for common things you want to do with objects. In other words - it's much easier to write:   c = a + b than   c = a.addition(b) ans it's also much easier for the maintainance ...	2011-08-13
3252	C++ - unknown array size, unknown object type. Help! There are time when you're writing a program where you say "I don't know". • I don't know how many records / object I'm going to read from a data file into an array - so I can't set the size of my array • I don't know what sort of object I'll be creating from a line I've read from a data ...	2011-04-17
3124	C++ - putting the language elements together into a program On the final day of the C++ course yesterday, I demonstrated a number of advanced features and pulled together various strands that we had been learning through the week. At one level, each feature of the language can be explained and taught, but there's a further level that's need to show how they ...	2011-01-08
1675	Comparing Objects in C++ Comparing two objects You can run a method on an object in C++ (or in any other OO language) to find an attribute of that object - let's say how costly it is (example, how costly it is to jave your group see a film). But you can't really run a method on TWO or more objects, which is what you would ...	2008-06-13
1478	Some new C programming examples - files, structs, unions etc A series of new "C" examples have been added to the web site - a course for a small group allowed me to go somewhat away from the more normal run yesterday and write some new illustrations in front of them. Call by value v call by pointer comparison: link Using extern to share a variable between two ...	2007-12-19
