函數iswpunct()用於檢查傳遞的寬字元是否為標點符號。如果不是標點符號，則傳回零，否則傳回非零值。它在“cwctype”頭檔中聲明。
以下是iswpunct()的語法：
int iswpunct(wint_t character);
這是iswpunct()的一個範例
#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;
}The character is a punctuation. The character is not a punctuation.
在上面的程式中，兩個寬字元被宣告為a和b。檢查傳遞的字元是否為標點符號。
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.");以上是在C/C++中，iswpunct()函數的作用是判斷一個寬字元是否為標點符號的詳細內容。更多資訊請關注PHP中文網其他相關文章！
