How to write structure record into file using fwrite() function?

[shivapadma]

1.i am just trying to insert a "structure record" into a file using fwrite() function by the following code

2.
#include<stdio.h>
#include<conio.h>
struct student
{
char name[20];
int rollno;
};
void main()
{
FILE *fp1;
struct student s1={"",0};
clrscr();
printf("enter the details\n");
scanf("%s %d",s1.name,&s1.rollno);
printf("%d\n",s1.rollno);
fp1=fopen("empdet.txt","w");
fwrite( &s1,sizeof( struct student ),1,fp1 );
printf("the record is entered");
fclose(fp1);
getch();

}

3.when i executed the above program,it just inserting only the "name" field and
the "rollno" field with some garbage

4.please,someone help me....

The rollno member of the struct is an int but the file is a text file.

Convert the int to a string and write the string.

Or open the file as a binary file but don't expect to view the contents with a text editor.

now i am able to insert both name and rollno.
