Write a C Program to Store Information Using Structures with Dynamically Memory Allocation.
Solution:
#include <stdio.h>
#include<stdlib.h>
struct item
{
float Cost,MRP;
char name[30];
};
int main()
{
struct item *ptr;
int i, noOfItems;
printf(“Enter number of items: “);
scanf(“%d”, &noOfItems);
// Allocates the memory for noOfRecords structures with pointer ptr pointing to the base address.
ptr = (struct item*) malloc(noOfItems * sizeof(struct item));
for(i = 0; i < noOfItems; i++)
{
printf(“Enter name of the Item, Cost and MRP respectively:\n”);
scanf(“%s %f %f”, (ptr+i)->name, &(ptr+i)->Cost, &(ptr+i)->MRP);
}
printf(“Item details as follows:\n”);
for(i = 0; i < noOfItems ; i++)
printf(“%s\t%.2f\t%.2f\n”, (ptr+i)->name, (ptr+i)->Cost, (ptr+i)->MRP);
return 0;
}
Output:
Enter no.of Items: 2
Enter name of the Item, Cost and MRP respectively:
Pen
15
20
Enter name of the Item, Cost and MRP respectively:
Book
36
55
Item details as follows:
Pen 15 20
Book 36 55
