UString is a class in the stdlib package of C++ that represents a Unicode string. The length() method of the UString class returns the number of characters in the string.
Here are some code examples using length() method:
Example 1:
std::u16string str = u"Hello World!"; int len = str.length(); std::cout << "Length of string is: " << len << std::endl;
Explanation: In this example, we create a UString variable called "str" that contains the string "Hello World!". We then use the length() method to determine the length of the string, which is 12. We output this length to the console.
Package library: stdlib
Example 2:
UString str("こんにちは"); int len = str.length(); std::cout << "Length of string is: " << len << std::endl;
Explanation: In this example, we create a UString variable called "str" that contains the Japanese word for "hello". We then use the length() method to determine the length of the string, which is 5 because the string contains 5 characters. We output this length to the console.
Package library: unknown (it could be a custom library developed by the programmer)
Example 3:
std::wstring_convert> convert; std::wstring str = convert.from_bytes("Γεία σου κόσμε"); UString ustr(str); int len = ustr.length(); std::cout << "Length of string is: " << len << std::endl;
Explanation: In this example, we create a std::wstring_convert object and use it to convert an UTF-8 encoded string to wide-character string. We then create a UString object called "ustr" using this wide-character string. We then use the length() method to determine the length of the string, which is 14 because the string contains 14 characters. We output this length to the console.
