Printf function

The printf () function returns a formatted string.

Syntax:

Printf (format,arg1,arg2,arg++)

The parameter format is the format of the conversion, starting with a percentage sign ("%") and ending with the converted character.

Here are the possible format values: *%%-returns the percentage symbol

*% b-binary number *% c-character according to ASCII value *% d-signed decimal number *% e-sustainable counting (e.g. 1.5e+3) *% u-unsigned decimal number *% f-floating point number (local settings aware) *% F-floating point number (not local settings aware) *% o-octal number *% s-string *% x- Hexadecimal number (lowercase) *% X-hexadecimal number (uppercase) arg1 Parameters such as arg2, arg++, etc., are inserted at the percent sign (%) symbol in the main string. The function is executed step by step, inserting arg1 in the first% symbol, arg2 at the second% symbol, and so on.

If the% symbol is more than the arg parameter, you must use a placeholder. After the placeholder is inserted with the% symbol, it consists of numbers and "\ $".

You can use numbers to specify the parameters displayed. For more information, please see the example.
