Why is n++ faster than n=n+1?

The answer is related to the old CISC cpu instructions and the way how C (or any programming language) is compiled to binary code. In almost every CISC CPU there is a special “add” instruction that is named INC (or DEC) and that instruction increments (or decrements) by 1 the value of a register (or memory). If you use another instruction for addition you have to add both operands you want to sum.

Why Did Google Develop Go ?

Google has two tremendous problems. One of them is compile time. Back in the 1980’s, reasonable sized projects took hours to do a clean build. There were whole server farms dedicated to recompiling. You got a new “nightly build” and made modifications to that. Google builds things that are so ridiculously huge that it’s still like that in 2017. It takes 5 hours to rebuild chrome from scratch even on a big fat i7 system.

Go Programming Language

Go in a Nutshell is .. Imperative language Statically typed Syntax tokens similar to C (but less parentheses and no semicolons) and the structure to Oberon-2 Compiles to native code (no JVM) No classes, but structs with methods Interfaces No implementation inheritance. There’s type embedding, though. Functions are first class citizens Functions can return multiple values Has closures Pointers, but not pointer arithmetic Built-in concurrency primitives: Goroutines and Channels Basic Syntax of Go Programming Language Hello World Example File hello.
