Example
Try following example to understand all the miscellaneous operators available in Go programming language −
Live Demopackage main import "fmt" func main() { var a int = 4 var b int32 var c float32 var ptr *int /* example of type operator */ fmt.Printf("Line 1 - Type of variable a = %T\n", a ); fmt.Printf("Line 2 - Type of variable b = %T\n", b ); fmt.Printf("Line 3 - Type of variable c= %T\n", c ); /* example of & and * operators */ ptr = &a /* 'ptr' now contains the address of 'a'*/ fmt.Printf("value of a is %d\n", a); fmt.Printf("*ptr is %d.\n", *ptr); }
When you compile and execute the above program it produces the following result −
Line 1 - Type of variable a = int Line 2 - Type of variable b = int32 Line 3 - Type of variable c= float32 value of a is 4 *ptr is 4.
