Learn the go language my exercise answer Chapter3

This is a creation in Article, where the information may have evolved or changed. This chapter is mainly about the use of functions in the go in the process of doing exercises a few of the more memorable problem is the definition of a named return function but did not put it in parentheses the result has been compiled, but I still do not know how to wrong a
And one of the things that impresses me is that go's strong type checking, and the way variables are declared, are clearly the same as the one in C/C + +, before you define an array as if you've seen the pointer in a/C + + definition of where the * is placed and where the array [] should be placed. All data types in Go For example: var test_var int Test_var This variable is of type int this variable declares that if it is in the function of the body of the Var is necessary but can be used inside the function: = to define this and = or the difference between the definition and the assignment is completely separate the more write the more you think it is a C + + upgrade Version hehe
