The example is available as a tarball here. The files are also available as syntax-highlighted HTML here (fatals.* and hrtime.h are elided). The latter portion of this document assumes the reader is following along using the syntax-highlighted Makefile and main.C. Installing Thread Building Blocks.

Introduction to Parallel Programming and MapReduce - Google Code University - Google Code. Templates. Overloading operators Classes, essentially, define new types to be used in C++ code.


And types in C++ not only interact with code by means of constructions and assignments. They also interact by means of operators. For example, take the following operation on fundamental types: Here, different variables of a fundamental type (int) are applied the addition operator, and then the assignment operator. Here, it is not obvious what the result of the addition operation on b and c does. Operators are overloaded by means of operator functions, which are regular functions with special names: their name begins by the operator keyword followed by the operator sign that is overloaded. Type operator sign (parameters) { /*... body ...*/ } For example, cartesian vectors are sets of two coordinates: x and y. The function operator+ of class CVector overloads the addition operator (+) for that type. Both expressions are equivalent.

For example: The keyword this Static members Const member functions. Basic Input/Output. The example programs of the previous sections provided little interaction with the user, if any at all.

Basic Input/Output

They simply printed simple values on screen, but the standard library provides many additional ways to interact with the user via its input/output features. This section will present a short introduction to some of the most useful. C++ uses a convenient abstraction called streams to perform input and output operations in sequential media such as the screen, the keyboard or a file. A stream is an entity where a program can either insert or extract characters to/from. The standard library defines a handful of stream objects that can be used to access what are considered the standard sources and destinations of characters by the environment where the program runs: Standard output (cout) On most program environments, the standard output by default is the screen, and the C++ stream object defined to access it is cout.

Abstract Class vs Interface. Introduction: There are lost of discussion on the internet about the Interface vs Abstract class.

Abstract Class vs Interface

C++ Interface Classes - An Introduction. Class hierarchies that have run-time polymorphism as one of their prominent characteristics are a common design feature in C++ programs, and with good design, it should not be necessary for users of a class to be concerned with its implementation details.

C++ Interface Classes - An Introduction

One of the mechanisms for achieving this objective is the separation of a class's interface from its implementation. Some programming languages, e.g. Java, have a mechanism available in the language for doing this. In Java, an interface can contain only method signatures. In C++ however, there is no such first class language feature, and the mechanisms already in the language must be used to emulate interfaces as best as can be achieved.

C - Odd Pearson correlation coefficient results. I have an assignment in my C programming class to write a program to get the correlation coefficient of 2 sets of real numbers.

c - Odd Pearson correlation coefficient results

I've been given the equations, and it referenced wikipedia so I double checked the equations there. Here is a link to the equation, which seems to be pretty standard from my research: I've written the program, but when I ran it I was getting numbers greater than 1 for my results, which I knew wasn't correct. I looked over my code several times but couldn't find anything out of place, so I tried dividing by n at the end instead of n-1, this gave me values with the -1 to 1 range that I expected, so i tested it against data values that I found online as well as a correlation coefficient calculator ( ) and I'm now getting correct results for all of the numbers I input.
