Create a text file that stores a First name a last name and

Create a text file that stores a First name, a last name, and an age, one record per line.

The C program will read a line of text from this file and then create a structure (what other languages would call a record) containing that data. Then write the object in a new binary file. The binary file that you have created should contain a series of records, each record containing a first name, last name and an age.

The program should then close the file and re-open it for input, read the file record by record and display on the screen, one record per line.

Solution

#include<stdio.h>

struct student
{
int age;
char fname[20],fname[20];
float fee;
};

void main()
{
FILE *fp;
char ch;
struct student s;
clrscr();

fp=fopen(\"s5.bin\",\"wb\");

while(1)
{
printf(\"\ Enter student details:\");
scanf(\"%s%s%d\",s.fname,s.lname,&s.age);
fwrite(&s,sizeof(s),1,fp);
fflush(stdin);
printf(\"Another record?[y/n]:\");
ch=getche();

if(ch!=\'y\')
break;
}
fclose(fp);
}
