Number of words in a string

Mini exercise: count the number of words in a string. bonus points: count the number of characters in each word Note: you can do both in one pass

Short Exercise:

Create a function to “bisect” a string given a delimiter: "id=fubar", '=' should return id and fubar. Prototype:

std::pair<std::string, std::string>
bisect(std::string_view str, char delim);

pair can be found in <utility>.
string_view instead of string const& allows for use of string literals / C strings without suffering a pointless string allocation.

Create a function to read the contents of a file at a given path into a vector of strings, each representing a line.

// File:
tag=fubar
xp=523

// Result:
{"tag=fubar", "xp=523"}

Prototype:

std::vector<std::string> readString(std::string_view path);

Use the above functions to read a configuration file into the fields of a struct. Eg:

struct SaveData
{
  std::string username;
  s32 windowWidth;
  s32 windowHeight;
  bool bFullscreen;
  bool bVsync;
};
