The isblankfunction in C language Checks whether the character is a blank character (space or tab).

The isblank function tests whether c is a blank character; that is, a space or a tab. This function was introduced in C99.

The isblankfunction takes 1 parameter:

•
int `c`: The character to be tested, passed as an `unsigned char` cast to an `int`, or `EOF`

Checks if the given character `c` is a blank character (either a space `' '` or a horizontal tab `\t`). Returns a nonzero value if `c` is blank, and `0` otherwise.

The isblank function return value :

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

Output

This example demonstrates basic usage of isblank with various characters.
