Control Structures

Inside of the folder "/02_control_structures" we have everything to work

Go to the file "01_if.go", if is easy to understand on golang, 'if', 'else if' and 'else'
Now to the file "02_for.go". With for we have all loops, the first for we can see "init"; "conditional"; "loop-expression"
The second for loop only we can see "conditional", is an while loop...
The third for loop is an infinite loop, "for(;;)" or "while (true)"
