即之前的slice := array[2:4]等价于slice := array[2:4:10],在Go 1.2中因为引入了新的语法,即支持第三个参数,可以调整切片的容量。 “第二个冒号引入容量值,该值必须小于或等于源切片或数组的容量” slice := array[2:4:7]的cap为 7-2=5 ...

In the "Application arguments:" text box you can enter the command line test parameters, e.g., -o -i -h C:\Projects\go2cs\src\Tests\Behavioral\ArrayPassByValue. When the active solution configuration targets "Debug" you can run the go2cs project to convert Go code, then run converted...

To check if array contains a specific element in Go, iterate over elements of array using a for loop, and check for the equality of values using equal to operator. If there is a match, we may stop the search and conclude that the element in present in the array. ...
