What values do these literals represent? What type does each have

int main() {
  "Who goes with F\145rgus?\012";  // character string literal containing two octal escape sequences
  3.14e1L;  // floating-point literal, type is `long double`
  1024f;  // floating-point literal, type is `float`
  3.14L;  // floating-point literal, type is `long double`

  return 0;
}
