读取汉字

首先判断你的机器汉字占几个字节

#include <stdio.h>

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

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

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

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

        return 0;
}

#include<stdio.h>
#define MAX 1024
int main(){
	char str[MAX];
	char *target=str;
	char ch;
	int length=0;
	printf("请输入一个字符：");
	fgets(str,MAX,stdin);
	while(1){
		ch=*target++;
		if(ch=='') {
			break;
		}
		if((int)ch<0){
			target+=1;
		}
		length++;
	}
	printf("你输入了%d个字符",length-1);
}
