从键盘输入一个字符串和一个十进制整数,将它们写入"K4.TXT"文件中,然后再从"K4.TXT"文件中读出并?

#include <stdio.h>
#include <string.h>
int main()
{
FILE *fp;
int num;
char str[255];
/*write*/
fp = fopen("K4.TXT","w");
if(fp == NULL) return 1;
scanf("%s,%d",str,&num);
fprintf(fp,"%s,%d",str,num);
fclose(fp);
/*read*/
fp = fopen("K4.TXT","r");
if(fp == NULL) reutrn 1;
fscanf(fp,"%s,%d",str,&num);
printf("%s,%d",str,num);
fclose(fp);

return 0;
}

嘻嘻，其实只用fprintf,fscanf这两个函数就可以了。
