std::isspace

int isspace( int ch );

Checks if the given character is whitespace character as classified by the currently installed C locale. In the default locale, the whitespace characters are the following:

• space (0x20, ' ')
• form feed (0x0c, '\f')
• line feed (0x0a, '\n')
• carriage return (0x0d, '\r')
• horizontal tab (0x09, '\t')
• vertical tab (0x0b, '\v')

The behavior is undefined if the value of ch is not representable as unsigned char and is not equal to EOF.

Parameters

Return value

Non-zero value if the character is a whitespace character, zero otherwise.
