How to set Chinese in C language

The methods for setting Chinese output in C language are: use the WideCharToMultiByte function to convert wide characters into multi-byte strings, and then output. Use the setlocale function to set the system locale to Chinese, and then output a Chinese string.

Setting Chinese method in C language

C language itself does not support Chinese output and needs to be implemented through other methods Chinese output. The two most common methods are:

1. Use the WideCharToMultiByte function

<code class="c">#include <windows.h>

int main() {
  wchar_t wideString[] = L"你好，世界！";
  char buffer[512];
  int size = WideCharToMultiByte(CP_UTF8, 0, wideString, -1, buffer, sizeof(buffer), NULL, NULL);
  if (size > 0) {
    printf("%s\n", buffer);
  }
  return 0;
}</code>

This method converts a wide character string into a multibyte string, which can then be used printf function output.

2. Use the setlocale function

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

int main() {
  setlocale(LC_ALL, "zh_CN.UTF-8");
  printf("你好，世界！\n");
  return 0;
}</code>

This method sets the system locale to Chinese, and then uses the printf function to output the Chinese string.
