f. Demonstrate a program in C to create a data file named score.dat to store students' information with Reg no, name, gender, and address. The program should ask the user to continue or not. When finished, the program should also display all the records in the proper format.

# Develop a program in C using a structure to ask for the information of any 12 students with roll_number, name, and marks scored in sub1, sub2, and sub3. Also, display them in proper format along with the calculation of total and percentage. [Note: the full marks of each subject are 100).

#include <stdio.h>

struct Student{

int roll;

char name[50];

float sub1,sub2,sub3,total,per;

};

int main(){

struct Student data[3];

int i;

 for(i=0;i<3;i++){

printf("Enter roll number, name and marks of sub1,sub2,sub3 of %d student\n",i+1);

scanf("%d%s%f%f%f",&data[i].roll,&data[i].name,&data[i].sub1,&data[i].sub2,&data[i].sub3);

 }

 for(i=0;i<3;i++){

data[i].total=data[i].sub1+data[i].sub2+data[i].sub3;

data[i].per= data[i].total/3;

 }

 printf("Roll \t Name \t Sub1 \t Sub2 \t Sub3 \t Total \t Percentage\n");

 for(i=0;i<3;i++){

printf("%d \t %s \t %.2f \t %.2f \t %.2f \t %.2f \t %.2f\n",data[i].roll,data[i].name,data[i].sub1,data[i].sub2,data[i].sub3,data[i].total,data[i].per);
