求解一个关于getc与putc的问题。
#include<stdio.h>
#include<stdlib.h>
int main(int argc,char *argv[])
{
int ch;
FILE *fp;
int count=0;
if(argc!=2)
{
printf("Usage:%s filename\n",argv[0]);
exit(1);
}
if((fp=fopen(argv[1],"r"))==NULL)
{
fprintf(stderr,"Can't open the file!\n");
exit(1);
}
while(ch=getc(fp)!=EOF)
{
putc(ch,stdout);
count++;
}
if(fclose(fp)!=0)
fprintf(stderr,"Error in closing files.\n");
printf("File %s has %ld characters\n",argv[1],count);
return 0;
}
