Check if character has graphical representation Checks whether c
is a character with graphical representation. The characters
with graphical representation are all those characters than can
be printed (as determined by isprint) except the space character
(' '). For a detailed chart on what the different ctype
functions return for each character of the standard ANSII
character set, see the reference for the <cctype> header. In
C++, a locale-specific template version of this function
(isgraph) exists in header <locale>. - Character to be checked,
casted to an int, or EOF. A value different from zero (i.e.,
true) if indeed c has a graphical representation as character.
Zero (i.e., false) otherwise. /* isgraph example */ int main ()
FILE * pFile; c = fgetc (pFile); if (isgraph(c)) putchar (c); }
while (c != EOF); This example prints out the contents of
"myfile.txt" without spaces and special characters, i.e. only
prints out the characters that qualify as isgraph. - Check if
