C语言如何写文件如何将文件名用参数代替？#includestdio.h
#includestdlib.h
#includestring.h
int main()
{
char username[]="abc";//应该是字符串
//char *filename = "c:\\data\\a.xml";//参数文件保存路径，根据需要修改
char filename[100];//定义字符数组,数组可修改不同字符串 。
FILE *file;//指向文件的指针
memset(filename,'\0',100);//初始化数组
printf("input your filename.\n");
gets(filename);
while(*filename!=NULL)//当连续输入2个回车，代表不再输入 。
{
//用于打开文件
if ((file = fopen(filename, "w+" )) == NULL)
{
//lr_output_message("Unable to create %s", filename);
printf("unable to open.\n ");
exit(0);
}
fwrite(username,sizeof(username),1,file);
fclose(file);//关闭文件
printf("input your filename.\n");
memset(filename,'\0',100);
gets(filename);
}
printf("finish.\n");
return 0;
}
参考下
如果系统能生成20110228111111.xml，把它变成字符串存到某个数组中,假如b[100]
可以用for(i=0;i100;i++)
{ ...
strcpy(filename,b);//将b拷贝到filename中
...处理文件写入
