Two newbie C++ related questions
Hey guys, I have two questions. When we are not using 'using namespace std;' in front of what extactly we have to put std::?
Second question, when we are using Switch and not if, else if, else.. how we can compare if variable is less or bigger then some number?
For example here is how we do it with if.. if(x > 10) { std::cout << "this rocks" << std::endl;}
thanks guys

anything which is defined in the std namespace (eg containers, streams, algorithms etc etc) - see http://www.cplusplus.com/reference/

you don't. For switch you have to test on equality (or default for a value that doesn't match any previous case). See http://www.learncpp.com/cpp-tutorial...ch-statements/
