STRUCTURE POINTERS

• Problem Description

  
  1. Create a Structure "grocery" with following data members:
  a. qty - int
  b. price - float
  c. amount - float
  d. itemname - char
  
  2. In main method declare structure variable as "itm"
  Hint: struct grocery itm
  
  3. Create an another structure pointer variable 
  Hint: struct grocery *pitem
  
  4. Assign the pointer assignment of itm to pitem
  Hint: pitem=&itm;
  
  5. Input the values of product name, price, quantity
  Hint: pitm->itemname
  
  6. Calculate the total amount as:
  pitem->amount =(float)pitem->qty * pitem->price;
  
  7. Display the details of itemname, price, quantity and totalamount
  
  
  Note: The structure variables, data members and structure name are CASE Sensitive.
  
  Follow the same case mentioned in the mandatory

• CODING ARENA

• #include <stdio.h>

  struct grocery

    {

    int qty; 

    float price,amount;

    char itemname[50];

    };

  int main()

  {

    struct grocery itm; 

    struct grocery *pitem; 

    pitem=&itm; 

    scanf("%s",pitem->itemname);

    scanf("%f",&pitem->price); 

    scanf("%d",&pitem->qty); 

    pitem->amount=(float)pitem->qty*pitem->price; 

    printf("Name=%s",pitem->itemname);

    printf("\nPrice=%f",pitem->price);

    printf("\nQuantity=%d",pitem->qty);

    printf("\nTotal Amount=%.2f",pitem->amount);

  
  

  return 0;

  }
