bookChallenge: Find Element Index

Opgave

Swipe to start coding

Write a function named findIndex that takes a std::vector<int> and an int value as arguments. Use the std::find algorithm from the Standard Library to search for the value in the vector. If the value is found, return its index; if not, return -1.

  • Use the std::find algorithm to perform the search.
  • Return the zero-based index of the found element.
  • Return -1 if the value is not present in the vector.
