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 can use a regex match to see if the string contains all uppercase letters: var uppercaseletters = /^[A-Z]+$/; if(data2.match(uppercaseletters)) { document.write(‘hey’); } else { document.write(‘nope’); } 2 solved Testing for uppercase, why is toUppercase() alphanumeric in javascript? [closed]

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]
since this got answers, for full clarity: Remove -WhatIf when you’re running it. Get-ChildItem | Rename-Item -NewName {$_.Name -creplace “[A-Z]”} -WhatIf This pipes Get-ChildItem into Rename-Item and then Sets the NewName to be the old name, except we’ve case-sensitively replaced any capital letters with nothing. 3 solved Powershell & Regex – How to find and … Read more
