fread()와 fwrite()사용도중... 일..

#include<stdio.h>
 
void main(){
	FILE*fp=fopen("binary.bin","wb");
	FILE*fp2=fopen("binary.bin","rb");
 
	int i;
	int c=1;
	int count;
 
	if(fp==NULL || fp2==NULL){
		puts("파일오픈 실패!!");
		return;
	}
 
	printf("숫자: %d\n", c);
 
	count=fwrite((void*)&c,sizeof(int),1,fp);
	printf("쓴 숫자의 갯수: %d\n", count);
	//fseek(fp,SEEK_SET,0); 또는 fclose(fp);;
	count=fread((void*)&i,sizeof(int),1,fp2);
	printf("읽은 숫자 갯수: %d\n", count);
	printf("숫자: %d\n",i);
	//fclose(fp);
	fclose(fp2);
	return;
