uppercase

I'm looking for a simple and basic way (ideal for beginners to learn the easiest way) to write a program in C++ which gets a string from the user and outputs the number of uppercase letters, lowercase letters and integers (numbers). I'm pretty amateur at using C++ syntax so please help me with an easy-to-understand syntax. Thanks! EDIT: Here is a very simple code that I found in Google and did some changes and corrections: #include <iostream> #include <conio.h> using namespace std; int main() { char array1[50]; int i = 0, lowercase = 0, uppercase = 0, numbers = 0, total; cout << "Enter a

I am trying to write a program that when a single letter is inputted, if it's in uppercase, leave it in uppercase and return it, and if it's in lowercase, then convert to uppercase. How do I write this to be able to tell if the string is originally in uppercase or lowercase? Just convert the string to upper case and compare it with the original string == string.upcase or for lowercase string == string.downcase Edit: as mentioned in the comments the solution above works with English letters only. If you need an international solution instead use def upcase?(string) !string[/[[:lower:]]/] end

Need your help on conversion of java objects to json. current the json result showing all the key in small letter case, i need it to be upper case. ObjectMapper mapper = new ObjectMapper(); Writer strWriter = new StringWriter(); mapper.writeValue(strWriter, obj); String jsonString= strWriter.toString(); and the result is [{"flags":"1","name":"Peter","location":"London","startDate":"2012-01-06 00:00"}] but i want results like this (all key key value should be in UPPER CASE): [{"FLAGS":"YU","NAME":"Peter","LOCATION":"London","STARTDATE":"2012-01-06 00:00"}] and also is it possible to get like

I want to modify a Swift string by converting some characters to uppercase, some others to lowercase. In Obj-c I had following : - (NSString*) lowercaseDestination:(NSString*) string { NSUInteger length = string.length; unichar buf[length+1]; [string getCharacters:buf]; BOOL up = true; for (int i=0; i< length ; i++) { unichar chr = buf[i]; if( .... ) { buf[i] = toupper(chr); } else { buf[i] = tolower(chr); } } string = [NSString stringWithCharacters:buf length:length]; return string; How would you do that in Swift 2 ? I did no find any Character method to upper or lower the case. Would be an

This may seem like a silly question, but after going through pages of google, i havnt been able to find the answer i want. s1.setName(JOptionPane.showInputDialog("Enter Name: "); For the above piece fo code, how would i format the data the user entered to be all capitals? Any help here would be appreciated. The String class has a toUpperCase() method on it. JOptionPane.showInputDialog(..) returns a String, so you can use: JOptionPane.showInputDialog("Enter name: ").toUpperCase(); See String.toUpperCase() Remember that String is immutable, so this creates a duplicate string 来源： https:/
