计算中文+字母混合的长度
char *str="Windows 7 操作系统";
用 strlen(str) 只返回字节数 18 ，但我要反回字符数(包括空格)：14
#include "stdio.h"
void main()
{
int ennum=0,chnum=0;//英文字母计数和汉字计数
char *str="Windows 7 操作系统";
int i;
for(i=0;str;i++)
{
if(('A'<=str&&'Z'>=str)||('a'<=str&&'z'>=str))
ennum++;
if(str<0) chnum++;
printf("英文字母数为：",ennum);
printf("中文字数为：",chnum/2);//这个很关键的，因为两个字节表示一个汉字
}
}
计算长度
char str[] = "some srting";
int length = sizeof(str) / sizeof(str[0]);
int length = strlen(str);
