struct student {
    char firstName[50];
    int roll;
    float marks;
}  s[10];

int main() {
    int i;
    printf("Enter information of students:\n");
    for (i = 0; i < 5; ++i) {
        s[i].roll = i + 1;
        printf("\nFor roll number%d,\n", s[i].roll);

        printf("Enter first name: ");
        scanf("%s", s[i].firstName);

        printf("Enter marks: ");
        scanf("%f", &s[i].marks);
    printf("********Display Information********\n\n");

    // Displaying information
    for (i = 0; i < 5; ++i) {
        printf("\nRoll number: %d\n", i + 1);
        printf("First name: ");
        printf("Marks: %.1f", s[i].marks);
    return 0;

  • This program is used to store and display the student information by using Structures.
  • A Structure student is created which holds three members a string array firstName of the size 50, an integer roll and float type marks.
  • An array of the structures s is then created of the size 5 for storing the data about 5 students.
  • In main(), the program requests the user to enter the information about the students and uses a for loop to take data of 5 students and stores it in the structure array s.
  • Finally, the program uses another for loop that is used to display the data of 5 students from the structure array.
