此程序用于统计文件字符个数
#include<stdio.h>

{char fname[80];/*存储文件名*/
FILE *rfp;
long count;/*文件字符计数器*/

clscr();
printf("Please input the file's name:\n");
scanf("%s",fname);
if((rfp=fopen(fname,"r"))==NULL)
{
printf("Can't open file %s.\n",fname);
exit(1);
}
count=0;
while(fgetc(rfp)!=EOF)
   count++;
fclose(rfp);/*关闭文件*/
printf("There are %ld characters in file %s.\n",count,fname);
