图片文件合成器

代码如下：

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

int main (void)
{
FILE *f_pic,*f_file,*f_finish;
char ch, pic_name[20],file_name[20],finish_name[20];

printf("请输入需要合成的图片和文件的名称：\n");
printf("图片：");
scanf("%s",pic_name);
printf("文件：");
scanf("%s",file_name);
printf("生成为：");
scanf("%s",finish_name);

if(!(f_pic=fopen(pic_name,"rb")))
{
printf("Can not open the picture %s !",pic_name);
exit(0);
}
if(!(f_file=fopen(file_name,"rb")))
{
printf("Cannot open the file %s !",file_name);
exit(0) ;
}
if(!(f_finish=fopen(finish_name,"wb")))
{
printf("Cannot open the file %s !",finish_name);
exit(0) ;
}
while(!(feof(f_pic)))
{
ch=fgetc(f_pic);
fputc(ch,f_finish);
}
fclose(f_pic);
while(!(feof(f_file)))
{
ch=fgetc(f_file);
fputc(ch,f_finish);
}
fclose(f_file);
fclose(f_finish);

system("pause");
return 0;
}
