C program to store information using structures with dynamic memory allocation code example

Example: WAP to read and print ‘n’ student details using structure and Dynamic Memory Allocation.

/*C program to read and print the N student 
details using structure and Dynamic Memory Allocation.*/
 
#include 
#include 
 
/*structure declaration*/
struct student
{
    char name[30];
    int roll;
    float perc;
};
 
int main()
{
    struct student *pstd;
    int n,i;
     
    printf("Enter total number of elements: ");
    scanf("%d",&n);
     
    /*Allocate memory dynamically for n objetcs*/
    pstd=(struct student*)malloc(n*sizeof(struct student));
     
    if(pstd==NULL)
    {
        printf("Insufficient Memory, Exiting... \n");
        return 0;
    }
     
    /*read and print details*/
    for(i=0; iname);
        printf("Enter roll number: ");
        scanf("%d",&(pstd+i)->roll);
        printf("Enter percentage: ");
        scanf("%f",&(pstd+i)->perc);
    }
     
    printf("\nEntered details are:\n");
    for(i=0; iname,(pstd+i)->roll,(pstd+i)->perc);
    }
