Program to maintain student details using files
Program:
#include<stdio.h>
#include<conio.h>
void main()
{
FILE *fptr ;
int i, n, rollno, s1, s2;
char name[10];
clrscr() ;
fptr = fopen("STUDENT.DAT", "w") ;
printf("Enter the number of students : ");
scanf("%d", &n);
for(i = 0 ; i < n ; i++)
{
printf("\nEnter the roll number : ");
scanf("%d", &rollno);
printf("\nEnter the name : ");
scanf("%s", name);
printf("\nEnter the marks in 2 subjects : ");
scanf("%d %d", &s1, &s2);
fprintf(fptr, "%d %s %d %d \n", rollno, name, s1, s2);
}
fclose(fptr);
fptr = fopen("STUDENT.DAT", "r");
printf("\nRoll No. Name \t\t Sub1 \t Sub2 \t Total\n\n");
for(i = 0; i < n; i++)
{
fscanf(fptr,"%d %s %d %d \n", &rollno, name, &s1, &s2);
printf("%d \t %s \t\t %d \t %d \t %d \n", rollno, name, s1, s2, s1 + s2);
}
fclose(fptr);
getch();
}
Output:
Enter the number of students : 2
Enter the roll number : 101
Enter the name : Udaya
Enter the marks in 2 subjects : 75 80
Enter the roll number : 157
Enter the name : Viji
Enter the marks in 2 subjects : 60 70
Roll No. Name Sub1 Sub2 Total
101 Udaya 75 80 155
