I have been working on a lyric game that takes the lyrics from a text file and then converts them to an array of words. The text file is divided into songs by a certain arrangement of symbols.
Each song is enclosed by a "~(insertnumberhere)~' at the start and a "~!(insertnumberhere)~" at the end, eg. "~1~" "words words words" "~!1~"
It then takes this text and converts it to a string using the function I wrote: txtout(), then from a string to a vector of words using the function I wrote: getlyrics(), and then for each song, I convert the vector to an array for use in the game.
The game asks the player which song he would like to use to play, and he picks between 2 songs. Then the song is converted from the text file to the array of words using the previously mentioned steps.
Then it picks a random spot in the song and a random number of words to output. The user must then input the next words in the song. If he gets it correct, he gets points, otherwise, the game goes back to the start. The more words he adds, the more points he gets.
I believe the problems I am getting are not with my functions but rather with the for, if and while loops I use in the game itself. Once I reach those points I start getting weird situations where the incorrect lyrics text and prompt for user input keep repeating indefinitely and other strange errors. Any help would be appreciated.
The start of the game is the start of the main function. I will write out a mock text file to emulate the way my text file works but with fake songs to avoid any issues:
~1~ Words words words words words, words. Words! ~!1~
~2~ Hello Hello hello hi hi hi Hello, hi there, how are you. ~!2~
