iswprint( ) in C++
We are given with the task to show the working of iswprint( ). The iswprint( ) function in C++ STL is used to check that whether the given wide character can be printed or not. It is a function present in cwctype header file in C++. Wide characters is a computer character datatype that generally has a size greater than the traditional 8-bit character.
Syntax
int iswprint(c);
Parameter
c – This is a parameter which specifies the wide character that has to be checked whether it is printable or not.
Return Value
This function returns a non-zero value if c can be printed. It will return zero if c cannot be printed.
Following characters given below are printable −
Upper case letters − A - Z
Lowercase letters − a - z
Digits − 0 - 9
Punctuation character − ! ” @ # $ % ^ & * ( ) } | \ ] [ _ - + ’ ? / . , } : ; ~ `
Space − ……
intable or not.
Example
#include <cwchar.h>
#include<iostream.h>
#inlude<cwctype.h>
Using namespace std;
int main( ){
wchar_t str[ ] = “ authorized<channel<partners”;
wcout<<str;
for( int i = 0; i < wcslen(str); i++){
if ( !iswprint(str[i]))
str[i] = ‘ @ ’;
}
wcout<<str;
return 0;
}Output
If we run above code it will generate the following output
authorized<channel<partners authorised@channel@partners
Example
#include <cwchar.h>
#include<iostream.h>
#inlude<cwctype.h>
Using namespace std;
int main( ){
wchar_t str[ ] = “ and I am<= Iron Man”;
wcout<<str;
for( int i = 0; i < wcslen(str); i++){
if ( !iswprint(str[i]))
str[i] = ‘ & ’;
}
wcout<<str;
return 0;
}Output
if we run above code it will generate the following output
and I am<= Iron Man and I am &&Iron Man
