This is a list of operators in the C and C programming languages.All the operators listed exist in C; the fourth column 'Included in C', states whether an operator is also present in C. Note that C does not support operator overloading. C programming is a general-purpose, procedural, imperative computer programming language developed in 1972 by Dennis M. Ritchie at the Bell Telephone Laboratories to develop the UNIX operating system. C is the most widely used computer language. It keeps fluctuating at number one scale of popularity along with Java programming language, which is also equally popular and most widely used among modern software programmers. The null coalescing operator (called the Logical Defined-Or operator in Perl) is a binary operator that is part of the syntax for a basic conditional expression in several programming languages, including C#, PowerShell as of version 7.0.0, Perl as of version 5.10, Swift, and PHP 7.0.0.

C++ is a middle-level programming language developed by Bjarne Stroustrup starting in 1979 at Bell Labs. C++ runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX. This C++ tutorial adopts a simple and practical approach to describe the concepts of C++ for beginners to advanded software engineers.

Why to Learn C++

C++ is a MUST for students and working professionals to become a great Software Engineer. I will list down some of the key advantages of learning C++:

• C++ is very close to hardware, so you get a chance to work at a low level which gives you lot of control in terms of memory management, better performance and finally a robust software development.

• C++ programming gives you a clear understanding about Object Oriented Programming. You will understand low level implementation of polymorphism when you will implement virtual tables and virtual table pointers, or dynamic type identification.

• C++ is one of the every green programming languages and loved by millions of software developers. If you are a great C++ programmer then you will never sit without work and more importantly you will get highly paid for your work.

• C++ is the most widely used programming languages in application and system programming. So you can choose your area of interest of software development.

• C++ really teaches you the difference between compiler, linker and loader, different data types, storage classes, variable types their scopes etc.

There are 1000s of good reasons to learn C++ Programming. But one thing for sure, to learn any programming language, not only C++, you just need to code, and code and finally code until you become expert.

Hello World using C++

Just to give you a little excitement about C++ programming, I'm going to give you a small conventional C++ Hello World program, You can try it using Demo link

C++ is a super set of C programming with additional implementation of object-oriented concepts.

There are many C++ compilers available which you can use to compile and run above mentioned program:

• Apple C++. Xcode

• Bloodshed Dev-C++

• Clang C++

• Cygwin (GNU C++)

• Mentor Graphics

• MINGW - 'Minimalist GNU for Windows'

• GNU CC source

• IBM C++

• Intel C++

• Microsoft Visual C++

• Oracle C++

• HP C++

It is really impossible to give a complete list of all the available compilers. The C++ world is just too large and too much new is happening.

Applications of C++ Programming

As mentioned before, C++ is one of the most widely used programming languages. It has it's presence in almost every area of software development. I'm going to list few of them here:

• Application Software Development - C++ programming has been used in developing almost all the major Operating Systems like Windows, Mac OSX and Linux. Apart from the operating systems, the core part of many browsers like Mozilla Firefox and Chrome have been written using C++. C++ also has been used in developing the most popular database system called MySQL.

• Programming Languages Development - C++ has been used extensively in developing new programming languages like C#, Java, JavaScript, Perl, UNIX’s C Shell, PHP and Python, and Verilog etc.

• Computation Programming - C++ is the best friends of scientists because of fast speed and computational efficiencies.

• Games Development - C++ is extremely fast which allows programmers to do procedural programming for CPU intensive functions and provides greater control over hardware, because of which it has been widely used in development of gaming engines.

• Embedded System - C++ is being heavily used in developing Medical and Engineering Applications like softwares for MRI machines, high-end CAD/CAM systems etc.

This list goes on, there are various areas where software developers are happily using C++ to provide great softwares. I highly recommend you to learn C++ and contribute great softwares to the community.

Prerequisites

Before you start practicing with various types of examples given in this C++ tutorial,we are making an assumption that you are already aware of the basics of computer program and computer programming language.

C or Do is the first note of the C majorscale, the third note of the A minor scale (the relative minor of C major), and the fourth note (F, A, B, C) of the Guidonian hand, commonly pitched around 261.63 Hz. The actual frequency has depended on historical pitch standards, and for transposing instruments a distinction is made between written and sounding or concert pitch.

In English the term Do is used interchangeably with C only by adherents of fixed-Do solfège; in the movable Do system Do refers to the tonic of the prevailing key.

Frequency[edit]

Historically, concert pitch has varied. For an instrument in equal temperament tuned to the A440 pitch standard widely adopted in 1939, middle C has a frequency around 261.63 Hz (for other notes see piano key frequencies). Scientific pitch was originally proposed in 1713 by French physicist Joseph Sauveur and based on the numerically convenient frequency of 256 Hz for middle C, all C's being powers of two. After the A440 pitch standard was adopted by musicians, the Acoustical Society of America published new frequency tables for scientific use. A movement to restore the older A435 standard has used the banners 'Verdi tuning', 'philosophical pitch' or the easily confused scientific pitch.

Octave nomenclature[edit]

Middle C[edit]

Middle C (the fourth C key from left on a standard 88-key piano keyboard) is designated C₄ in scientific pitch notation, and c′ in Helmholtz pitch notation; it is note number 60 in MIDI notation.^[1]

While the expression Middle C is generally clear across instruments and clefs, some musicians naturally use the term to refer to the C note in the middle of their specific instrument's range. C₄ may be called Low C by someone playing a Western concert flute, which has a higher and narrower playing range than the piano, while C₅ (523.251 Hz) would be Middle C. This technically inaccurate practice has led some pedagogues to encourage standardizing on C₄ as the definitive Middle C in instructional materials across all instruments.^[2]

On the Grand Staff, middle-C is notated with a ledger line above the top line of the bass staff or below the bottom line of the treble staff. Alternatively, it is written on the centre line of a staff using the alto clef, or on the fourth line from the bottom, or the second line from the top, of staves using the tenor clef.

Other octaves[edit]

In vocal music, the term High C (sometimes less ambiguously called Top C^[3]) can refer to either the soprano's C₆ (1046.502 Hz; c′′′ in Helmholtz notation) or the tenor's C₅; both are written as the C two ledger lines above the treble clef but the tenor voice sings an octave lower. The term Low C is sometimes used in vocal music to refer to C₂ because this is considered the divide between true basses and bass-baritones: a basso can sing this note easily, whereas other male voices, including bass-baritones, typically cannot.

Tenor C is an organ builder's term for small C or C₃ (130.813 Hz), the note one octave below Middle C. In stoplists it usually means that a rank is not full compass, omitting the bottom octave.

Designation by octave[edit]

20,000 hertz is the start of the ultrasound in healthy young adults. Note that for a classical piano and musical theory, the middle C is usually labelled as C₄; However, in the MIDI standard definition (like the one used in Apple's GarageBand), this middle C (261.626 Hz) is labelled C₃. In practice, a MIDI software can label middle C (261.626 Hz) as C₃-C₅, which can cause confusions, especially for beginners.

B sharp[edit]

Traversing the circle of fifths can result in a B♯ that is higher than C by 23.46 cents, the ratio of twelve just perfect fifths (B♯) to seven octaves being 531,441 / 524,288, the Pythagorean comma. A B♯ that is three just major thirds above C is lower than the octave by an interval called a diesis, 125:128 or 41.06 cents.
