Question

Suppose a pointer to a structure, bookPtr is defined. This structure also contains a member, price that is a pointer to a double. Provide the equivalent to *bookPtr- > price?

Answer 1

equivalent to *bookptr->price is (*bookptr).price)

//below demonstrated the same

#include<stdio.h>

//book struct is defined

typedef struct book

{

double price;

};

int main()

{

//created book structure

struct book *bookptr=(struct book*)malloc(sizeof(struct book)*1);

//printing the data

printf("%d\n",bookptr->price);

//using another way to print from struct pointer

printf("%d",(*bookptr).price);

return 0;

}

//compiling and running the code (some garbage value will print as not initialized the price value)

printed by *bookptr->price 7428816 printed by ("bookptr).price) 7428816 Process exited after 0.2549 seconds with return value 5 6 2 Press any key to continue

Please do let me know if u have any doubts..
