In C programming, isspace( ) checks whether a character is white-space character or not. If a character passed to isspace( ) is white-space character, it returns non-zero integer if not it returns 0.

The isspace() function shall test whether c is a character of class space in the program's current locale; see the Base Definitions volume of IEEE Std 1003.1-2001, Chapter 7, Locale.

The isspace() method returns True if all the characters in a string are whitespaces, otherwise False.

September 13, 2024 - The isspace() function returns an integer value that tells whether the passed parameter is a whitespace character or not.

For a detailed chart on what the different ctype functions return for each character of the standard ASCII character set, see the reference for the <cctype> header. In C++, a locale-specific template version of this function (isspace) exists in header <locale>.

TF = isspace(A) returns a logical array TF. If A is a character array or string scalar, then the elements of TF are logical 1 (true) where corresponding characters in A are space characters, and logical 0 (false) elsewhere.

isspace tests an integer value c to determine whether it is white space; that is, a blank, tab, new line, carriage return, form feed, or vertical tab character.

The isspace() and isspace_l() functions shall test whether c is a character of class space in the current locale, or in the locale represented by locale, respectively; see the Base Definitions volume of POSIX.1‐2017, Chapter 7, Locale. The c argument is an int, the value of which the application ...

December 16, 2005 - The function isspace() tests whether its character argument produces whitespace rather than a glyph when printed—such as a space, tabulator, newline, or the like.

#include <cctype> #include <climits> #include <iomanip> #include <iostream> int main(void) { std::cout << std::hex << std::setfill('0') << std::uppercase; for (int ch{}; ch <= UCHAR_MAX; ++ch) if (std::isspace(ch)) std::cout << std::setw(2) << ch << ' '; std::cout << '\n'; }

April 23, 2025 - Home / Programming / Language Reference / Functions / isSpace() Last revision 04/23/2025 · Analyze if a char is a white-space character. Returns · true if the input char is a space, form feed ( '\f'), newline ( '\n'), carriage return ( '\r'), horizontal tab ( '\t'), or vertical tab ( '\v').

These functions check whether c, which must have the value of an unsigned char or EOF, falls into a certain character class according to the current locale.

April 2, 2025 - What is isspace()? The isspace() function is part of the C standard library and is defined in the <ctype.h> header file. It is used to check whether a given character is a whitespace character.

October 3, 2023 - The .isspace() string method takes in a string and returns True if the entire string is composed of whitespace characters, otherwise False.

The isspace() and isspace_l() functions test for whitespace characters.

June 6, 2023 - This is a post for myself, because ... C standard library function isspace() returns a non-zero value (true) for the six "standard" ASCII white-space characters ('\t', '\n', '\v', '\f', '\r', ' '), and any locale-specific characters....
