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
#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.");
以上是在C/C++中,iswpunct()函数的作用是判断一个宽字符是否为标点符号的详细内容。更多信息请关注PHP中文网其他相关文章!
