文件处理问题
输入框不能停止结束,不知道原因,代码如下:#include <stdio.h>
#include <stdlib.h>
#define SIZE 4
struct student
{
char name;
int phone;
char addr;
}stu;
void main()
{
int i;
printf("Please input the student's name phone and address: \n");
for(i=0; i<SIZE; i++)
{
scanf("%s %d %s",&stu.name,&stu.phone,&stu.addr);
}
save();
system("pause");
}
void save()
{
FILE *fp;
int i;
if(!(fp = fopen("student.txt","wb")))
{
printf("Cannot find the file!\n");
return;
}
for(i=0; i<SIZE; i++)
{
if( fwrite(&stu,sizeof(struct student),1,fp) != 1)
{
printf("File write error!\n");
fclose(fp);
}
}
}
怎么没人指点一下?我运行以后输入的是5组数组元素,不明白???{:5_94:} 我输入的是四组啊,没有问题吧
#include <stdio.h>
#include <stdlib.h>
#define SIZE 4
struct student {
char name;
int phone;
char addr;
} stu;
void save()
{
FILE *fp;
int i;
if(!(fp = fopen("student.txt","wb"))) {
printf("Cannot find the file!\n");
return;
}
for(i=0; i<SIZE; i++) {
if( fwrite(&stu,sizeof(struct student),1,fp) != 1) {
printf("File write error!\n");
fclose(fp);
}
}
}
void main()
{
int i;
printf("Please input the student's name phone and address: \n");
for(i=0; i<SIZE; i++) {
scanf("%s %d %s",&stu.name,&stu.phone,&stu.addr);
}
save();
system("pause");
}
