04. Challenge 1 Solution
Here's my solution:
#include <iostream>
int main() {
std::cout << "no more steering wheels" << std::endl;
return 0;
}
std
refers to namespace
std
and the
<<
operator passes sequences of characters to stdout. In fact, two sequences of characters get passed to stdout:
"no more steering wheels"
and
std::endl
, a newline character (
std::endl
also flushes the buffer).
You may be used to adding a
using namespace std
line after your
include
statements - however, under the
Google C++ style guide
, you should not utilize
using-directives
to make all names from a namespace available. You could instead use
using std::cout;
and
using std::endl;
near the top so that you do not have to re-write
std::
before each instance of these - it does not make much of a difference here, but could be more helpful when you use them multiple times!
It's worth noting that
"no more steering wheels"
is not a string like a Python string, rather it's a
char []
- a sequence of characters.
Time for another! Let's control some flow.
