Use spaces sparingly

Reason

Too much space makes the text larger and distracts.

Example, bad

#include < map >

int main(int argc, char * argv [ ])
{
    // ...
}

Example

#include <map>

int main(int argc, char* argv[])
{
    // ...
}

Note

Some IDEs have their own opinions and add distracting space.

This is a recommendation for when you have no constraints or better ideas. This rule was added after many requests for guidance.

Note

We value well-placed whitespace as a significant help for readability. Just don't overdo it.
