fcopy.c

实现字符串的复制功能,可以进行拓展,从而实现更加强大的功能.

#include<stdio.h>
#include<stdlib.h>
void main()
{
  FILE *in,*out;
  char ch,infile[10],outfile[10];
  printf("Enter the infile name:\n");
  scanf("%s",infile);
  printf("Enter the outfile name:\n");
  scanf("%s",outfile);
  if((in=fopen(infile,"r"))==NULL)
  {
    printf("cannot open infile\n");
	exit(0);
  }
  if((out=fopen(outfile,"w"))==NULL)
  {
    printf("cannot open outfile\n");
	exit(0);
  }
  while(!feof(in)) fputc(fgetc(in),out);
  fclose(in);
  fclose(out);
}
