编程学习网为您整理以下代码实例，主要实现：宽字符的操作，希望可以帮到各位朋友。
#include <stdio.h>
#include <wchar.h>
#include <wctype.h>
int main(voID){
wchar_t ch = 0; // Stores a character
fwprintf(stdout, L"Enter a character:\n ");
fwscanf(stdin, L" %lc", &ch, sizeof(ch)); // Read a non-whitespace character
if(iswalnum(ch)) // Is it a letter or a digit?
{
if(iswdigit(ch)) // Is it a digit?
fwprintf(stdout, L"You entered the digit %lc\n", ch);
else if(iswlower(ch)) // Is a lowercase letter?
fwprintf(stdout, L"You entered a lowercase %lc\n", towupper(ch));
else
fwprintf(stdout, L"You entered an uppercase %lc\n", towlower(ch));
}
else if(iswpunct(ch)) // Is it punctuation?
fwprintf(stdout, L"You entered the punctuation character %lc.\n", ch);
else
fwprintf(stdout, L"You entered %lc, but I don't kNow what it is!\n", ch);
return 0;
}
