C/C++ 中的 iswpunct() 函数
函数 iswpunct() 用于检查传递的宽字符是否是标点符号。如果不是标点符号则返回零,否则返回非零值。它在 “cwctype” 头文件声明中。
以下是 iswpunct() 的语法
int iswpunct(wint_t character);
以下是 iswpunct() 的示例
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,两个宽字符分别声明为 a 和 b。字符检查传递的字符是否是标点符号。
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.");
