In ascii how many characters can be created

However, not all have characters ex. No matter what you call them, it is often crucial to know which one is being used, so it's best to avoid the term "Extended ASCII. In , IBM developed an extension of 8-bit ASCII code, called "code page ", in this version were replaced some obsolete control characters for graphic characters.

Jones O. Jones This starts off well, but then somehow loses track. The diversion about punched tape is tangential at best, and how does the final paragraph follow from the things you say above? In the newer 6th edition , the code example states: if str.

Then use the explorer and look at the size of the file. You will find that the file has a size of 30 bytes on disk: 1 byte for each character. If you add another word to the end of the sentence and re-save it, the file size will jump to the appropriate number of bytes.

Each character consumes a byte. If you were to look at the file as a computer looks at it, you would find that each byte contains not a letter but a number -- the number is the ASCII code corresponding to the character see below.

So on disk, the numbers for the file look like this:. Some method is needed for indicating the length of the string, or where the end of the string is.

There are two main methods:. The programmer must of course know the convention being used. There is nothing to distinguish bits which mean numbers, from bits which means letters and characters; you have to know what the bits are supposed to mean before you can do anything with them.
