請問這個程式怎么實作通過檔案的方式輸入雇員資訊，及工資標準。并將不同雇員的工資情況輸入到檔案中。
uj5u.com熱心網友回復：
用這套檔案api實作如：#include <stdio.h>
#define SIZE 2
struct student_type
{
char name[10];
int num;
int age;
char addr[10];
}stud[SIZE];
void save()
{
FILE *fp;
int i;
if((fp=fopen("stu_list","wb"))==NULL)
{
printf("cant open the file");
exit(0);
}
for(i=0;i<SIZE;i++)
{
if(fwrite(&stud[i],sizeof(struct student_type),1,fp)!=1)
printf("file write error\n");
}
fclose(fp);
}
main()
{
int i;
for(i=0;i<SIZE;i++)
{
scanf("%s%d%d%s",&stud[i].name,&stud[i].num,&stud[i].age,&stud[i].addr);
save();
}
for(i=0;i<SIZE;i++)
{
printf("%s,%d,%d",stud[i].name,stud[i].num,stud[i].age,stud[i].addr);
}
}
fread.c
#include <stdio.h>
#define SIZE 2
struct student_type
{
char name[10];
int num;
int age;
char addr[10];
}stud[SIZE];
void read()
{
FILE *fp;
int i;
if((fp=fopen("stu_list","rb"))==NULL)
{
printf("cant open the file");
exit(0);
}
for(i=0;i<SIZE;i++)
{
if(fread(&stud[i],sizeof(struct student_type),1,fp)!=1)
printf("file write error\n");
}
fclose(fp);
}
main()
{
int i;
read();
for(i=0;i<SIZE;i++)
{
printf("%s,%d,%d,%s",stud[i].name,stud[i].num,stud[i].age,stud[i].addr);
printf("\n");
}
}
