## Stanford C essentials

Stanford CS Education Library This [the following section until marked as end of Stanford University items] is document #101, Essential C, in the Stanford CS Education Library. This and other educational materials are available for free at http://cslibrary.stanford.edu/.

### Other Assignment Operators

In addition to the plain = operator, C includes many shorthand operators which represents variations on the basic =. For example “+=” adds the right hand side to the left hand side. x = x + 10; can be reduced to x += 10;. This is most useful if x is a long expression such as the following, and in some cases it may run a little faster.

person->relatives.mom.numChildren += 2;    // increase children by 2

Here’s the list of assignment shorthand operators…

 +=, -= Increment or decrement by RHS *=, /= Multiply or divide by RHS %= Mod by RHS >>= Bitwise right shift by RHS (divide by power of 2) <<= Bitwise left shift RHS (multiply by power of 2) &=, |=, ^= Bitwise and, or, xor by RHS

# free music player coding example

Coding example: I am making heavily documented and explained open source code for a method to play music for free — almost any song, no subscription fees, no download costs, no advertisements, all completely legal. This is done by building a front-end to YouTube (which checks the copyright permissions for you).

Create your own copy from the original source code/ (presented for learning programming).

Because I no longer have the computer and software to make PDFs, the book is available as an HTML file, which you can convert into a PDF.
