Question

I’m programming hangman.

Question words are saved in char word_list[], const strings.

word_list[] = {"apple", "computer", ..., "mouse"};

Question is randomly selected from word_list[], and when I use random function I want to know the number of strings in word_list[].

word_list is the pointer of char*, right?

Finally, how can I know the number of strings in word_list[]??

Answer 1

If word_list[] is declared like your code snippet you can obtain the number of elements by doing:

const size_t word_count = sizeof(word_list) / sizeof(word_list[0]);

You might consider a more flexible method like reading a std::vector of std::string at run time. That would allow you to modify the word list without having to recompile and the vector::size() function would tell you the number of elements.
