I’m trying to give an answer that will help you understanding the problem and work on the solution. You have a string with capital letters and at some point there is a small letter. You want the string to be split at the position before the first small letter. You can iterate through the string … Read more
You need to call the method: month.lower() == ‘march’ The method is an object too, and without calling it you are comparing that method with a string. They’ll never be equal: >>> month=”January” >>> month.lower <built-in method lower of str object at 0x100760c30> >>> month.lower == ‘January’ False >>> month.lower == ‘january’ False >>> month.lower() … Read more
This looks like a homework question so I won’t solve it directly. However here are some steps you could take: Create a method to validate the input (public static boolean isValid(String str)) Convert the String to a character Array. (There’s a method for that!) Iterate over the letters and keep track of how many upper … Read more
I ran your code just as it is, and it printed it both in uppercase and lowercase, but I noticed you had a comment that said //Display the first character, and following it, keyboard.next(). This was the only incorrect part. To print the first letter of a string(in this case the string is city), use … Read more
This will run forever: for(a;strlen(tab);a++) I think you meant: for(a;a < strlen(tab);a++) Or better (because strlen is O(n)): for(;tab[a];a++) 3 solved tolower() and toupper() aren’t working [closed]
