Other than string literals, you have free usage of white space (spaces, tabs, newlines), and are able to use as much or as little as you like. C++ statements are delimited by semicolons, so in the following code there are three statements, which will compile and run:
int i = 4; i = i / 2; std::cout << "The result is" << i << std::endl;
The entire code could be written as follows:
int i=4;i=i/2; std::cout<<"The result is "<<i<<std::endl;
There are some cases where white space is needed (for example, when declaring a variable you must have white space between the type and the variable name), but the convention is to be as judicious as possible to make the code readable. And while it is perfectly correct, language-wise, ...
