C/C中的iswpunt（）函数++-yiteyi-C++库

这个 iswpunct（） 是C/C++中的一个函数，用于测试 宽字符码 代表着一种阶级特征点刺在程序的当前区域设置中。如果宽字符是标点符号宽字符代码，则返回非零，否则返回0。此函数在中定义 cwctype 头文件。该函数检查中国是不是标点符号。标点符号如下

null

! " # $ % & ' () * +, - . / : ;  ? @ [] ^ _ ` {|} ~

语法：

int iswpunct(ch)

参数： 该函数只接受一个强制参数中国它指定要检查的字符。

返回值： 如果字符ch是标点符号，则函数返回非零值，否则返回零。

下面的程序演示了上述功能：
