How the manipulation of characters is possible as numbers? Explain.
Answers
"Every character which we commonly use in for general purposes in our daily life can be represented using an equivalent ASCII (American Standard Code for Information Interchange) value.
The ASCII values of the characters are used for their manipulation as characters too.
For instance, the lower case English alphabet from a to z have values from the number 97 to the number 122 and the uppercase letters from the letter A to the letter Z have the ASCII values from 65 to the value 90.
Now, if we want to convert a character from lower case to upper case, we just have to take its ASCII value and subtract the difference between them with the respective ASCII value.
The uppercase letter A (65) can be obtained from lowercase a (97) by subtracting 32. i.e., 97 - 32 = 65"
