How to write Chinese in C language

Outputting Chinese in C language requires the following steps: Encode the source code file into UTF-8. Use the setlocale() function to set the locale: setlocale(LC_ALL, ""); use the printf() function to output Chinese, which requires a UTF-8 encoded string as a parameter.

How to output Chinese in C language

If you want to output Chinese in C language, you need to perform the following steps ：

1. Use UTF-8 encoding：
   C language uses ASCII character encoding by default and cannot directly output Chinese. Therefore, source code files need to be encoded as UTF-8.

2. Use the setlocale() function to set the locale :
   setlocale() The function sets the locale of the program. For Chinese output, you need to use the following code:

   <code class="c">setlocale(LC_ALL, "");</code>

3. Use printf() function to output Chinese :
   Use printf () When the function outputs Chinese, you need to use the %s placeholder in the format string and take the UTF-8 encoded string as a parameter. For example:

   <code class="c">printf("你好，世界！\n");</code>

Sample code:

<code class="c">#include <stdio.h>
#include <locale.h>

int main() {
    // 设置语言环境
    setlocale(LC_ALL, "");

    // 输出中文
    printf("你好，世界！\n");

    return 0;
}</code>
