In C, int, char, long, etc. are all integers. They typically have different memory sizes and thus different ranges as in INT_MIN to INT_MAX. char and arrays of char are often used to store characters and strings. Integers are stored in many types: int being the most popular for a balance of speed, size and … Read more
You could try something like:
Vertical tab was used to speed up printer vertical movement. Some printers used special tab belts with various tab spots. This helped align content on forms. VT to header space, fill in header, VT to body area, fill in lines, VT to form footer. Generally it was coded in the program as a character constant. … Read more
The Character class of Java API has various functions you can use. You can convert your char to lowercase at both sides: There are also a methods you can use to verify if the letter is uppercase or lowercase:
EOF is not a character (in most modern operating systems). It is simply a condition that applies to a file stream when the end of the stream is reached. The confusion arises because a user may signal EOF for console input by typing a special character (e.g Control-D in Unix, Linux, et al), but this character is not … Read more
String are immutable in Java. You can’t change them. You need to create a new string with the character replaced. Or you can use a StringBuilder:
Assuming Python 3 (in Python 2, this difference is a little less well-defined) – a string is a sequence of characters, ie unicode codepoints; these are an abstract concept, and can’t be directly stored on disk. A byte string is a sequence of, unsurprisingly, bytes – things that can be stored on disk. The mapping between them is … Read more
You can use string.indexOf(‘a’). If the char a is present in string : it returns the the index of the first occurrence of the character in the character sequence represented by this object, or -1 if the character does not occur.
Here’s an alternative since you don’t like the cast to int:
I use a for loop to iterate the string and use charAt() to get each character to examine it. Since the String is implemented with an array, the charAt() method is a constant time operation. That’s what I would do. It seems the easiest to me. As far as correctness goes, I don’t believe that exists here. It is … Read more
