C Program to Store Multiple Student Records Using Structure and Pointer

This C program allows users to input the number of students, store student records as a structure using pointers and prints student information. In this C Program below we will store the student’s name, roll, age and CGPA and eventually print them on the console.

Program:

#include <stdio.h>
#include <stdlib.h>

struct Student
{
    char name[30];
    long int roll;
    int age;
    float cgpa;
};

int main()
{
    int num_students;
    struct Student *student;
    
    printf("Please enter the number of students: ");
    scanf("%d", &num_students);
    
    student = (struct Student *) malloc(num_students * sizeof(struct Student));
    
    for(int i=1; i<= num_students; i++) 
    {
        printf("Please enter student %d's info: \n", i);
        printf("Name: "); 
        scanf("%s", (student+i)->name);
        printf("Roll: "); 
        scanf("%ld", &(student+i)->roll);
        printf("Age: "); 
        scanf("%d", &(student+i)->age);
        printf("CGPA: "); 
        scanf("%f", &(student+i)->cgpa);
        printf("\n");
    }
    
    for(int i=1; i<= num_students; i++) 
    {
        printf("Student %d info: \n", i);
        printf("Name: %s\n", (student+i)->name);
        printf("Roll: %ld\n", (student+i)->roll);
        printf("Age: %d\n", (student+i)->age);
        printf("CGPA: %f\n", (student+i)->cgpa);
        printf("\n");
    }
    

    return 0;
}

Output:
