I noticed that there is always space after operator (+) or even the double quotes “…” for strings. Why is this? Also, i have seen no space after ( but the other part of ) has space. I do not understand why it is what it is or what are the rules that govern this?
As for quotes on strings, if there is a space, it will be printed. The space would be there intentionally, for that purpose. If no space is desired, then no space is included.
"string " + "another string"
The first string has a trailing space, the second has neither leading nor trailing spaces. When the two are concatenated (joined into a single string), there will be a space between ‘string’ and ‘another’
"string another string"
As for operators, it is a good practice to surround them with white space so they can be easier to spot.
a * b + c
