Implement the iswgraph() : C

Hello, I am the student of the Msc-IT. I had learned the C language in BscIT. I also have the good knowledge of the functions in C language. i have to submit the assignment on the iswgraph() function. So, I would like to know about the iswgraph() function. I would also like to know how can I Implement the iswgraph() function in C language. If there is anyone who can have the solution on the iswgraph() functions then reply me!!!

Hi, how are you!!! The iswgraph function can be the equivalent to the wide-character of that of the isgraph() function. The iswgraph() function can the checks that whether the variable that can be declared as argument of the iswgraph()function, can be the wide character that is belonging to the " graph " class of the wide character. The class " graph " that can be of the wide character, can be a subclass of the class " print ".

The iswgraph() function can return the zero, if the argument of the iswgraph() function can not be a wide-character code. The iswgraph() function can return the non zero, if the argument of the iswgraph() function can be a wide-character code. The following can be the common errors that can fails the iswgraph() function :
1. EINVAL : Locale can not a valid locale object handle.

The following sample program can helps you to learn more about the iswgraph() function and how can you able to implement the iswgraph() function in the program :

Code:

---

#include <stdio.h>
#include <wctype.h>
int main(void)
{
  int CH;
  for (CH=0; CH <= 0xFF; CH++) {
      printf("%3d", CH);
      printf(" %#4x ", CH);
      printf("%2s", iswgraph(CH)  ? "G"  : " ");
      putchar(' \n ');
  }
}

---

Program :

Code:

---

#include <stdio.h>
#include <wctype.h>
char chr[] = {'B', 0x09, ' ', 0x7d};
#define SIZE sizeof( chr ) / sizeof( chr )
void main()
  {
    int  j;
    for( j = 0; j < SIZE; j++ ) {
      printf( "Char %c is %sa printable character\n",
        chr[j],
        ( iswgraph( chr[j] ) ) ? "" : "not " );
    }
  }

---

Output :

Code:

---

Char B is a printable character
Char    is not a printable character
Char  is not a printable character
Char } is a printable character
