Character
The keyword char
represents a single character. A character value is always enclosed in single quotes ('
).
main
Every character represents an integer value in the ASCII table. The ASCII table is a fundamental character encoding system used in computers to represent text and symbols. Each character, like letters, numbers, and punctuation marks, is assigned a unique numerical value that computers understand. This allows computers to exchange and display information in a standardized way.
For example, the character a
represents the value 97
while b
represents 98
. You can view the ASCII table at: ASCII table link
We can perform arithmetic operations on the characters. The operations always return an integer value based on the ASCII values of the characters being operated. For-example:
main
The above code outputs 195
because the sum of the ASCII values of a
and b
is 195
.
The digits from 0 to 9 can also be represented as characters by enclosing them in single quotes:
However, digits represented as characters are NOT the same as integers.
