Function Details : iswdigit

Read about return values of iswdigit function .

1st Parameter Type : wint_t

An integer type capable of storing any wide character value or the special value WEOF, used in wide-character input/output functions.

1st Parameter

The wide character to be tested, passed as a `wint_t`

The iswdigitfunction in C language Checks whether the wide character is a digit.

The iswdigit function tests whether wc is a wide character code representing a decimal digit character. In many locales, only the characters '0' through '9' are considered digits.

The iswdigitfunction takes 1 parameter:

•
wint_t `wc`: The wide character to be tested, passed as a `wint_t`

Checks if the given wide character `wc` is a decimal digit (0–9). Returns a nonzero value if `wc` is a digit, and `0` otherwise.

The iswdigit function return value :

Returns non-zero if the wide character is a digit, 0 otherwise

Output

This example demonstrates basic usage of iswdigit with various wide characters, including non-ASCII digits.
