linux下的程序开发（C语言实现）：本程序主要实现文件的操作

#include<stdio.h>
#include<stdlib.h>
int main(int argc,char *argv[])
{
	char a_buf[256],b_buf[256];
	FILE *fp;
	if((fp=fopen("./tmp","w+"))==NULL)
	{
		perror("fopen");
		exit(EXIT_FAILURE);
	}
	printf("input a string(<256):\n");
	scanf("%s",a_buf);
	fprintf(fp,"%s",a_buf);
	rewind(fp);
	fscanf(fp,"%s",b_buf);
	printf("%s\n",b_buf);
	fclose(fp);
	return 0;
}
