A quick view from C, C++ to VB.NET

There are many programming languages to program a computer. The most popular and basic ones are Basic, C, C++, Pascal, Java, and Assembler. Machine language is a collection of instructions, which controls the computer's hardware. Many programming languages are compilers and some programming languages are interpreters. Compilers translate the entire program into machine language before executing any of the instructions while interpreters proceed through a program by translating and then executing single or small groups of instructions such as line by line or statement by statement.

Actually, both compilers and interpreters are computer programs. That means C and C++ are computer programs that accept the inputs and generate an output. They accept source codes as inputs and generate object codes as an output.

C and C++: A Short Overview

C is the most popular structured programming language. It was invented and implemented by Dennis Ritchie. C builds on BCBL and B, which was developed by Martin Richards and Ken Thompson.

C grew with a book named The C Programming Language by Brian Kernighan and Dennis Ritchie (Prentice-Hall, 1978). The most important year is 1983 for C programming language. In 1983, a committee was organized to create ANSI standards for C. This standardization process took six years. Finally, first standards were adopted in late 1989. Also, 1990 and 1996 are important years for ANSI standards of C. The most recent standard for C was released. This book includes the full ANSI 99 C standard for C Programming Language.

C is used by programmers to design and develop any kind of programming. You can write source code for a system task or high level GUI design with C. Also, you can create your own source library with C. Even after many years, C has not lost its popularity. Today many programmers use C to generate their source code for different programming tasks.

Bjarne Stroustrup created C++ in the 1980s. C++ is based upon C and is a superior set of it. C++ is the most popular object oriented programming language with C power. Its first name was C with Classes. C++ offers programmers more power. Object oriented programming is the primary addition to C provided by C++. Another important addition is generic programming.

C++ has now been standardized with ANSI and ISO committees. The final draft international standards of C++ were released in late 1997 and the actual international standards were adopted in mid 1998.

As I said before, this book is written to be compliant with ANSI/ISO C and C++. You can compile and run source codes of this book (You can find all codes and examples in book's CD) with any ANSI/ISO standard C and C++ compiler tools.

VB.NET: Another Short Overview

VB.NET is a strong, modern, object-oriented and type-safe programming language. Also,  VB.NET probably will prove to be the most important new programming language since the advent of Java. VB.NET brings together Visual Basic simplicity, Java specification and the power of C++. At this point, I should say Borland at an earlier date developed products such as Delphi and C++ Builder which have offer some of the benefits of VB.NET.

The problem for C and C++ programmers was a rapid development combined with the power to access all the functionality of the underlying platform. Programmers want an environment that is completely in sync with emerging Web standards and one that provides easy integration with existing applications. Also, C and C++ developers would like the ability to code at a low level when and if the need arises.

Under this light, Microsoft solution to this problem is a language called VB.NET. Basically, VB.NET is the premier language being promoted by Microsoft for the .NET Platform.

The .NET framework's Common Language Runtime (CLR) is much similar to Java Virtual Machine (JVM), in terms of garbage collection, security, just in time compilation (JIT). However, the fundamental difference arises from the variance in perception of the Sun's Java design team headed by James Gosling and that of Microsoft's VB.NET designers .

The Common Language Runtime (CLR) is the runtime environment of the .NET framework, which manages the execution of code and provides services. The Common Language Runtime (CLR) is also proposed for ECMA standard. However, The ECMA documents refer the CLR as Common Language Infrastructure (CLI). It has five components namely

Using VB is required Common Language Runtime and the .NET Framework class library.  It is a new programming language. Microsoft decided to develop an Object Oriented and Web compatible programming language derived from C, C++ and Java. The result is VB.NET and VB.NET is stronger, more advantageous and easier to use than the others.
