What is character constant ?

Character constant is divided into two categories, first is single character constants and another string constants.

Single Character constants contain only a single alphabet, a single digit or a single special symbol enclosed within single inverted commas. Both the inverted commas should point to the left.

For example, ’A’ is a valid character constant whereas ‘A’ is not.

Ex.: 'a'

'A'

'9'

'='

String constant is a sequence of character i.e. it is collection of characters enclosed in double quotes.

Ex:       “ABC”

“123”

“12+45”
