Thread: Pointer to print name and price

C program Using Pointer to print the name and price of the items sold in a retail shop on a specific date.
I am unable to understand this question will somebody explain how can i program code for this. I know how to print name and price of the item using pointer but i am bit confuse "specific date" what's the exactly means? is it mean user will input a specific date and bunch of data will appear on his screen? so do i need to use any "Search Algorithm" ?

is it mean user will input a specific date and bunch of data will appear on his screen?

Probably.

so do i need to use any "Search Algorithm" ?

Yes. Have you tried anything?

Not Yet... I will come back with codes

Code:

#include<stdio.h>
#define SIZE 3
main()
{
    char item[SIZE][100];
    char *pi[SIZE];
    float price[SIZE];
    float *pp[SIZE];
    int date[SIZE],i, sea;
    int *pd[SIZE];
    printf("\t******************************\n\n");
    printf("\t\tMonth: December\n\t\tYear : 2015\n\n");
    printf("\t******************************\n\n");


    for(i=0; i<SIZE; i++)
    {
            printf("\nEnter Date: ");
            scanf("%d", &date[i]);
            pd [i] = &date[i];
            printf("Enter Item Name: ");
            scanf("%s", &item[i]);
            pi [i] = &item[i];
            printf("Enter Price: ");
            scanf("%f", &price[i]);
            pp [i] = &price[i];
    }
    printf("\nEnter Date for search: ");
    scanf("%d", &sea);
    printf("\n**************************\n");
    for(i=0; i<SIZE; i++)
    {
        if(sea == *pd[i])
        {
            printf("\nItem Name: %s\nPrice    : %0.2f\n", pi[i], *pp[i]);
        }
    }
}

Do you think I am going in correct path ?

I'm not sure what all the extra pointer arrays are supposed to do. Stuff like float *pp, char *pi, int *pd... you don't need these things. It looks like you're adding in layers of indirection for no good reason.

For example, you could just compare sea and date[i]:

Code:

if (sea == date[i])

This is just because Question is demanding me to use pointer for printing all those stuffs.
