C语言完美演绎9-27

/* 范例：9-27 */

#include <stdio.h>

#include <stdlib.h>

void main(int argc,int *argv\[\])

{

FILE *fp1,*fp2;

int ch,ret;

if(argc!=3)

{

printf("Syntax Error!\n\tp9-27 source target");

exit(1);

}

fp1=fopen(argv1,"rb");

fp2=fopen(argv2,"wb");

while(!feof(fp1))

{

ch = getc(fp1);

if(ch!=EOF)

putc(ch,fp2);

}

fclose(fp1);

fclose(fp2);

}

程序执行结果：(假设要把oo.txt复制成xx.txt)

D:\TC>p9-27 oo.txt xx.txt
