程序代码：

#include<stdio.h>
#include<stdlib.h>

int main(int argc,char *argv[])
{

 int ch;

 FILE *source,*destination;

 if ( (source = fopen(argv[1],"rb")) == NULL)

 {
  printf ("Can't open %s\n", argv[1]);
  exit(1);

 }

 if ( (destination = fopen(argv[2],"wb")) == NULL)

 {
  printf ("Can't open %s\n", argv[2]);
  exit(1);

 }

 while ((ch = getc(source)) != EOF)
  putc(ch,destination);

 fclose(source);

 fclose(destination);

 printf ("copy finished\n");

 return 0;
