Programm To Store Students Information Using Structure:
#include <stdio.h>
struct student {
char first_name[50];
char last_name[50];
int roll_number;
char grade [10];
} s[50];
int main() {
int x, i;
// x is the total no. of students
printf("Enter the number of students: ");
scanf("%d", &x);
// To store the student's information
printf("\nEnter the students's informations:\n");
for (i = 0; i < x; i++) {
s[i].roll_number = i + 1;
printf("\nInformation for Roll Number:\t%d\n", s[i].roll_number);
printf("Enter the first name: ");
scanf("%s", s[i].first_name);
printf("Enter the last name: ");
scanf("%s", s[i].last_name);
printf("Enter the Grade: ");
scanf("%s", s[i].grade);
}
// To display the student's information
printf("\n\nDisplay the student's information:\n");
for (i = 0; i < x; i++) {
printf("\nThe Roll Number:\t%d\n", i + 1);
printf("The First Name: ");
puts(s[i].first_name);
printf("The Last Name: ");
puts(s[i].last_name);
printf("The Grade: ");
