如果您选择使用简单的位运算执行大小写转换,则您编写的方法会比Java的方法稍微快一些,因为Java的方法有更复杂的逻辑来支持Unicode字符而不仅仅是ASCII字符集。 如果您查看String.toLowerCase(),您会注意到其中有很多逻辑,因此,如果您正在处理大量仅限于ASCII字符的软件,并且没有其他字符,那么使用更直接的方法可能会有...
the small letter of the word represents a lowercase character. While we utilize ASCII values to transform capital characters or strings to lowercase,
lowercase_string = str.lower(original_string) print(lowercase_string) # Output: "uppercase" 使用str.translate()和str.maketrans()的组合。 original_string = "UPPERCASE" lowercase_string = original_string.translate(str.maketrans(string.ascii_uppercase, string.ascii_lowercase)) print(lowercase_string)...

Toconvert an uppercase alphabet to lowercase alphabet– we can add32in uppercase alphabet's ASCII code to make it a lowercase alphabet (because the difference between a lowercase alphabet ASCII and an uppercase alphabet ASCII is32). In the below code, we created a user-defined...

If you want to use the UPPER or LOWER built-in functions to process Unicode and ASCII data, you must complete additional setup. You must also complete additional setup if you want to use uppercase or lowercase conversions for characters other than A–Z or a–z. Procedure T...
The method above is one way to do it, though I think for simple equality checks, a simple if statement should suffice: 1 2 if( letter =='a'|| letter =='A') ... Also, it may be helpful to remember uppercase and lowercase letters in ascii are always exactly 32 decimal values apar...
2) If we do 1 left shift 5 and if we take a '|' of it, we can turn the Upper case to Lower Case. cout << char('C' | 1 << 5) << endl; 3) More Cooler Trick — i) 1 left shift 5 can be switched with the ASCII value of space i.e. ' '. ...
