The Go Programming Langauge

-:Seminar On:-

Google’s Go Programming Language ---------------------------------Saurabh S. Gilalkar 11

Introduction Go is the open source system programming language developed by Google. •

It is experimental. It is simple and fast.

•

It can compile large programs in milliseconds. •

22

History • The initial design was started in Sep 2007 by, Robert Griesemer, Rob Pike, Ken Thompson.

• Officially announced in Nov 2009. • In May 2010, publicly stated that Go was being used "for real stuff" at Google. 33



Need of developing Go.. No major systems language has emerged in over a decade, but over that time the computing landscape has changed tremendously.





The emergence of multi-core computers has generated worry and confusion. The developers are not happy with the construction speed. They have to wait while the code is compiling.

Features of Go… It is based on the C programming language. It is simple and easy. It provides high speed compilation It supports multi-core computers. 55

Features of Go… Runs on Linux and MAC OS-X Platforms. New versions also runs on Windows. It is type safe and memory safe. It uses two compliers i.e. Gccgo which uses GCC at the back end and 6g for 64-bit architecture and 8g for 32-bit. 66

What is Difference with other language Simplicity in code writing

Few keywords, parsable without symbol table. Free from use of semicolon(;). They are optional. Go needs fewer parentheses for strusture like if, for and switch.

control

It supports pointer concept,But in limited manner.

88

Data Types int8,int16,int32,int64. uint8,uint16,uint32,uint64. Float32,float64. complex64 ,complex128. String. Other Types:ArrayType,SliceType,StructType,PointerType,Fun ctionType,InterfaceType,MapType,ChannelType.

Some Syntatical Difference if Statement if x > 0 {

return y

}

for Statment for i := 0; i < 10; i++ { //body of loop

} 1010

Some Syntatical Difference Direct variable decleration and Itialization i, j := 0, 10

//In C, int i=0,j=10;

Function Decleration:func min(x int, y int) int {

if x < y { return x } return y

/*In C int min(int x,inty) { if(x
