What is char and when i use it

Answer 1

A char is a datatype to store characters such as 'c', '0' or 'C'.

Answer 2

A char is a character data type, similar to a string, but only contains one character.

In the C language, a char has a storage size of 1 byte (8 bits) and the values can range from -128 to 127, or 0 to 255, or they may contain a letter or a symbol.

While strings and chars both use quotation marks, some programming languages indicate strings with double quotation marks (“ “) and characters with single quotation marks (‘ ‘).
