Function Details : iswalpha

intiswalpha(wint_t wc) ;

Return Type : int

Integer type (typically 4 bytes, -2,147,483,648 to 2,147,483,647)

Read about return values of iswalpha 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`

Read more about parameters of iswalpha in parameters section

The iswalphafunction in C language Checks whether the wide character is alphabetic.

The iswalpha function tests whether wc is a wide character code representing an alphabetic character.

The iswalphafunction 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 an alphabetic wide character (a letter). Returns a nonzero value if `wc` is alphabetic, and `0` otherwise.

The iswalpha function return value :

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

Output

This example demonstrates basic usage of iswalpha with various wide characters, including non-Latin scripts.
