Namespaces are there to prevent the collision of names. For example the standard library has class vector inside the std namespace. If you use another library like a graphic library, it isn't uncommon that there is another class called vector ( the math version ) in its own namespace. Without the namespaces your compiler wouldn't be able to tell which one you want to use. So they prevent ambiguity issues. So having a class just with static functions probably isn't a better alternative than a namespace.

Yes, just use myClass::hi() instead of myClass.hi() if the function is static. ( and move the class above main )
