The function iswpunct() is used to check that the passing wide character is a punctuation or not. It returns zero, if it is not a punctuation, otherwise it returns a non-zero value. It is declared in “cwctype” header file.
Here is the syntax of iswpunct()
int iswpunct(wint_t character);
Here is an example of iswpunct()
Example
#include<cwctype> #include<stdio.h> using namespace std; int main() { wint_t a = '!'; wint_t b = 'a'; if(iswpunct(a)) printf("The character is a punctuation."); else printf("\nThe character is not a punctuation."); if(iswpunct(b)) printf("\nThe character is a punctuation."); else printf("\nThe character is not a punctuation."); return 0; }
Output
The character is a punctuation. The character is not a punctuation.
In the above program, two wide characters are declared as a and b. The characters are checked that passed character is a punctuation or not.
wint_t a = '!'; wint_t b = 'a'; if(iswpunct(a)) printf("The character is a punctuation."); else printf("\nThe character is not a punctuation."); if(iswpunct(b)) printf("\nThe character is a punctuation."); else printf("\nThe character is not a punctuation.");
