If you have studied the Introduction to Programming in C course available on ALISON it is now time to further enhance your C programming skills by studying numbers, variables and arrays and the functionality they have in computer programming. In this free online C programming course you will gain a much greater knowledge and understanding of numbers, variables and arrays. You will learn more about the basics of numeric overflow and how numbers are encoded as characters in ASCII. You will learn more about variables and the connection between function return values and variables. You will also review the use of arrays and pointers, how to create a pointer in C, and assign a value to a pointer. This free online C programming course will be of great interest to IT professionals who want to enhance their knowledge and understanding of the C programming language and its functionality, and to those learners who want to follow on from the Introduction to Programming in C course.<br />

In computer science control flow is a very important concept to understand for the development of effective and efficient software programs. Control flow is the order in which individual statements, instructions, or function calls are executed within a piece of software. In this free online computer programming course you will learn more about the use of statements and logic in C programming. You will be introduced to conditional flow statements, the mechanisms for controlling flow statements, and how to implement simple statements in C. Logical operators such as OR, GOTO and the While loop are also discussed in detail. This free online computer programming course will be of great interest to all IT professionals who would like to learn more about the use of control flow when developing software using the C programming language, and to all learners who want to learn more about the procedures used to write effective software programs.<br />

C is a powerful system programming language and is commonly used to programme operating systems such as Unix. One of the main advantages of programming in C is that it allows the programmer to write directly to memory. This means that key constructs such as pointers, constants and strings can be used within the memory in an efficient and machine-independent fashion. This free online computer programming course covers topics such as using pointers for direct memory access and manipulation in C, changing the memory address contained within a pointer and introduces constants and string literals. You will learn why pointers contain memory addresses of multi-byte variables, and how to visualise RAM in a new way. This free online computer programming course will be of great interest to IT and software professionals who would like to learn more about this powerful and efficient programming language, and to all learners who would like to learn more about the kind of programming language that is used to develop operating systems.<br />

The free online course C# Programming - Coding with C# Classes and Methods shows you in a step-by-step manner how to use methods and classes in C# code. You will also learn about namespaces and accessibility modifiers.<br /><br />The course begins by showing you how to use classes and methods in C# programming and how to declare a new instance of a class. You will also learn how to work with classes and inheritances in the .NET Framework class library. You will learn about constructors which have the same name as the class, and usually initialize the data members of the new object. You will learn about constructor overloading, the name given to constructors with different sets of parameters. You will learn about inheritance which is the ability to create a class from another class, the &quot;parent&quot; class, extending the functionality and state of the parent in the derived or &quot;child&quot; class.<br /><br />You will learn about the FileStream class, which supports both synchronous and asynchronous read and write operations. You will learn how to code in C# using namespaces which are C# program elements designed to help you organize your programs. You will learn about the StreamReader class which implements a TextReader that reads characters from a byte stream in a particular encoding. You will also learn about scope and its use in C# programming. Finally, you will learn how to utilize the accessibility modifiers Public and Private.<br /><br />This free C# programming course will be of great interest to all learners who would like study a step-by-step introduction to coding using C# classes and methods and how to use Visual Studio Express for programming software applications.<br />

The free online course C# Programming - Coding with C# Syntax introduces you to the basics of coding correctly formatted C# syntax using Visual Studio Express from Microsoft. The course begins by showing you how to use Visual Studio Express, a free software package available from Microsoft, to write correctly formatted C# syntax in a step-by-step manner. You will learn how to write correct C# syntax for operators, expressions, and statements of duration. You will also learn how to declare and use for iterations, as well as create arrays of values and create, and call simple overload helper methods. The course then shows you how to declare and use while iterations, and the methods used to read data from a text file. You will also learn how to code with Strings and with DateTime. This free C# programming course will be of great interest to all learners who would like study a step-by-step introduction to coding using C# syntax and how to use Visual Studio Express for programming software applications.<br />

The free online course C# Programming - Coding with Switch Statements, Collections and Events shows you in a step-by-step manner how to code in C# using decision statements, collections and event-driven programming.<br /><br />The course begins by describing the different types of decision making statements such as the switch decision statement, if...else statement, and the if...else...if statement. In C# if you have a number of constants that are logically related to each other, then you can group together these constants in what are called enumerations. You will learn how to declare enumerations using the enum keyword. <br /><br />You will learn about using the try-catch statement when handling exceptions. In C# programming when handling exceptions the key is to check for the most specific first and then the more general exceptions. In a try-catch statement the order of the catch clauses is important because the catch clauses are examined in order. You will learn how to create and manage groups of related objects using collections. You will learn about Language-Integrated Query (LINQ) and how it offers a consistent model for working with data across various kinds of data sources and formats. You will learn how to use the C# WPF application and which parameters the AddHandler statement takes.<br /><br />This free C# programming course will be of great interest to all learners who would like study a step-by-step introduction to coding using C# decision statements, filter and manage collections using the LINQ application, program events, and use Visual Studio Express for programming software applications.<br />

C++ for Programmers is designed for students who are familiar with a programming language and wish to learn C++. This course focuses on 'how' as opposed to 'what'. For example, in the lesson on functions, we do not teach what a function is, but rather how to create a function in C++. The lessons are taught by several different instructors who have used C++ in their professional careers, so students get to experience different perspectives. The course also includes comments and tips from Bjarne Stroustrup - the original designer of C++.

A first course on C++ based on the book Accelerated C++.

This program will teach you how to get to the highest levels of the hospital or ambulatory care center. You will learn:
