Read Chinese characters

First, determine your machine characters occupy a few bytes

#include <stdio.h>

int main()
{
        char str[] = "中";
        int length, i;

        length = sizeof(str) / sizeof(str[0]);

        printf("length of str: %d\n", length);

        for (i = 0; i < length; i++)
        {
                printf("str[%d] = %d\n", i, str[i]);
        }

        return 0;
}

#include <stdio.h> 
#define MAX 1024 
int main () { 
	char STR [MAX]; 
	char * = target STR; 
	char CH; 
	int length = 0; 
	the printf ( "Enter a character:"); 
	fgets (STR , MAX, stdin); 
	the while (. 1) { 
		CH = * target ++; 
		IF (CH == '\ 0') { 
			BREAK; 
		} 
		IF ((int) CH <0) { 
			target + =. 1; 
		} 
		length ++; 
	} 
	the printf ( "you have entered% d characters",. 1-length); 
}
