[c++] Comparing strings, c++

.compare() returns an integer, which is a measure of the difference between the two strings.

  • A return value of 0 indicates that the two strings compare as equal.
  • A positive value means that the compared string is longer, or the first non-matching character is greater.
  • A negative value means that the compared string is shorter, or the first non-matching character is lower.

operator== simply returns a boolean, indicating whether the strings are equal or not.

If you don't need the extra detail, you may as well just use ==.
