字符统计(改1)

此次改进稍微加了一个文件名和文件存储位置的输入：

会继续改进的

#include<stdio.h>
#include<ctype.h>
#include<stdlib.h>
#include<string.h>
int character=0;//字符数
int word=0;//单词数
int space=0;//空格数
char words[1000];//单词存储
int wordnum=0;//单词存储的数组位置
int Word(char *f);
int show();//显示单词
int main()
{
    int choice;//选择的输入
    FILE *fp;//文件指针
    char c; //文件字符读取存储
    char filename[20] ;
    char place[10];
    char Openname[40];
    printf("请输入文件所在位置：");
    gets(place);
    printf("请输入文件名：");
    gets(filename);
    strcat(filename, ".txt");
    strcpy(Openname,place);
    strcat(Openname,"\\");
    strcat(Openname,filename);
