Answer 1

Parsing means to split up input by something called a delimiter, which can be any character such as space, comma, colon, semicolon, etc.. So take the string "This_is_a_string" and you wanted to parse it with a delimiter of _. That would break that string into 4 separate ones "This" "is" "a" "string", which you could store somewhere like a file, vector, array, etc.. Hopefully this helps.
