C program uses structure to store inventory system

Structure is a collection of variables of different data types, grouped together by a single name.

Characteristics of structures

The characteristics of structures in C language programming language are as follows-

All structural elements of different data types can be combined by using assignment Contents are copied to another structure variable of its type
In order to handle complex data types, it is better to create a structure within another structure, which is called a nested structure.
You can pass the entire structure, individual elements of the structure, and the address of the structure to the function.
Can create structure pointers.

Program

The following is a C programUsing structure to store inventory system -

#include<stdio.h>
#include<conio.h>
void main(){
   struct date{
      int day;
      int month;
      int year;
   };
   struct details{
      char name[20];
      int price;
      int code;
      int qty;
      struct date mfg;
   };
   struct details item[50];
   int n,i;
   printf("Enter number of items:");
   scanf("%d",&n);
   fflush(stdin);
   for(i=0;i<n;i++){
      fflush(stdin);
      printf("Item name:");
      scanf("%s",item[i].name);
      fflush(stdin);
      printf("Item code:");
      scanf("%d",&item[i].code);
      fflush(stdin);
      printf("Quantity:");
      scanf("%d",&item[i].qty);
      fflush(stdin);
      printf("price:");
      scanf("%d",&item[i].price);
      fflush(stdin);
      printf("Manufacturing date(dd-mm-yyyy):");
      scanf("%d-%d-%d",&item[i].mfg.day,&item[i].mfg.month,&item[i].mfg.year);
   }
   printf(" ***** INVENTORY *****</p><p>");
   printf("------------------------------------------------------------------</p><p>");
   printf("S.N.| NAME | CODE | QUANTITY | PRICE |MFG.DATE</p><p>");
   printf("------------------------------------------------------------------</p><p>");
   for(i=0;i<n;i++)
      printf("%d %-15s %-d %-5d %-5d%d/%d/%d</p><p>",i+1,item[i].name,item[i].code,item[i].qty,item[i].price,item[i].mfg.day,item[i].mfg.month,item[i].mfg.year);
   printf("------------------------------------------------------------------</p><p>");
