I'm currently writing a code using functions that will take in a users phrase, remove any extra spaces and then allow the user to re-assort the phrases as needed. This is one of my first time using functions and I'm stuck when I try to remove the spaces.
The code that I have written takes in the statement from the user input device. I then created a for loop that was supposed to iterate and find any spaces that were more than one. The problem is, when I pass the function check_phrase, all of my content is deleted and it keeps me enters an infinite loop, I believe.
I'm really stuck on this and I can't use strings to fix anything. It all has to be done using arrays of characters. Solutions with array advice would be the most appreciated. Thank you!
