c - 如何使用 Xcode 在 C 上显示扩展的 ascii 表？

Question

我正在 Xcode 上用 C 语言进行编程。我尝试使用 for 循环来查看每个数字会得到哪些字符，如下所示:

    printf("Lista of caracteres: \n");
    for (i=0;i<256;i++){
        printf("Caracter %d: %c \n", i, i);
    }

但从 128 开始，我从常规 ascii 表中得到了不同的结果。

Lista de caracteres:

Caracter 1:  
Caracter 2:  
Caracter 3:

Answer 1

您必须使用 wprintf 而不是 printf 并设置区域设置，如下所示:

#include <stdio.h>
#include <wchar.h>
#include <locale.h>

int main(void) {
    setlocale( LC_ALL, "en_US.UTF-8" );
    for (wchar_t i=0; i<=255; i++) {
        wprintf( L"Caracter %d: %lc\n", i, i);
    }

    return 0;
}
