In the short code below, I declared an array of five elements. But I'm getting confused on how to use it in a while loop. My main question is , if the user inputs a userchoice1 value that is less than 1, I want the code to keep looping until the user inputs a number that is not less than 1. But I don't know if the 7th line (userchoice1 [x]++) shows the right way to loop it.
