函数iswpunct()用于检查传递的宽字符是否为标点符号。如果不是标点符号，则返回零，否则返回非零值。它在“cwctype”头文件中声明。

以下是iswpunct()的语法：

int iswpunct(wint_t character);

这是iswpunct()的一个示例

示例

#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;
}

输出

The character is a punctuation.
The character is not a punctuation.

在上面的程序中，两个宽字符被声明为a和b。检查传递的字符是否为标点符号。

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.");
