24. Write a program to process the students-evaluation records using structures.

/* students evaluation records using structures */

# include<stdio.h>

# include<conio.h> main()

{

int choice; struct stud { int rollno; int subcode; int marks;

} studeval; FILE *f1;

clrscr();

f1=fopen("eval.dat","w"); while(1)

{

printf("Enter student roll no :"); scanf("%d",&studeval.rollno); printf("\nEnter subject code :"); scanf("%d", &studeval.subcode); printf("\nEnter marks obtained :"); scanf("%d", &studeval.marks);

fprintf(f1,"%d|%d|%d\n",studeval.rollno,studeval.subcode,studeval.marks); printf("Do you want to add another record (1 for YES 0 for NO) :"); scanf("%d",&choice);

if(choice==0)

{

fclose(f1); exit(0);
