Literals 🪨

Literals are values we defined in our source code that are fixed.

Integer Literal

To create an integer literal, we write the integer like how you would normally write it. The integer literal can have an optional negative sign.

Ex.

10
-10
0
2340

Float Literal

To create a float literal, we just write the number like how you would normally write it. The float literal can have an optional negative sign and an optional decimal point.

Ex.

10.2340
-10.204
0
2340.43438

Character Literal

To create a character literal, we can use single-quotes surrounding a single character:

Ex.

'a'
'#'
'&'
'9'

String Literal

To create a string literal, we can use double-quotes surrounding some text:

Ex.

"The quick brown fox"
"My name is Bob!"
"apples, peaches, grapes"
"101 Dalmatians"

Tip

You’ve already seen the string literal in action, because the string you put into printf() is a string literal.

printf("This is a string literal being used in printf!");
