Thread: Need help with C programming STRUCT!!!

Hello friends. here is my situation.
1. I am learning C programming myself with the help of the book C PROGRAMMING ABSOLUTE BEGINNERS GUIDE.


2. I am using code blocks ide compiler.


3. in this book now i am learning SETTING UP DATA WITH STRUCTURES. And I have an example of the STRUCT.

Code:

//header file "bookInfo.h" saved in the same folder
struct bookInfo {
    char title[40];
    char author[25];
    float price;
    int pages;
};

Code:

#include "bookInfo.h" // header file already created and saved in the same folder.
#include <stdio.h>


main()


{
int ctr;
struct bookInfo books[3];


for (ctr = 0; ctr < 3; ctr++)
{
printf("What is the name of the books #%d?\n", (ctr+1));
gets(books[ctr].title);
puts("Whos the author? ");
gets(books[ctr].author);
puts("How much did the book cost? ");
scanf(" $%f", &books[ctr].price);
puts("How many pages in the books? ");
scanf(" %d", &books[ctr].pages);
getchar();


}


printf("\n\nHere is the collection of books: \n");
for (ctr = 0; ctr <3; ctr++)
{
printf("#%d: %s by %s", (ctr+1), books[ctr].title, books[ctr].author);
printf("\nIt is %d pages and costs $%.2f", books[ctr].pages, books[ctr].price);
printf("\n\n");
}
return(0);
}

now the prob is when i compile the program
1. it works ok upto
puts("How many pages in the books? ");


after this it does not take any value...just printing on the screen n jumping to new loop n start from 2nd iteration.


i am completely lost here. dont understand what to do here. please HELP.

First you should never, Never, NEVER use gets(). This function is so unsafe it has been removed from the current C standard. I recommend you replace your gets() calls with fgets() which can be safely used.

Next be careful when you place other characters in your scanf() specifier string. Remember if you place a spurious character in the specifier you must also enter this character. For example with your "price" field you must enter the '$' along with the numeric value. I recommend you place this character in the prior puts and only use the "%f" specifier, also note the lack of the space. Remember with numeric entries scanf() skips white space characters by default.

Jim thanks a lot. this is such a small mistake which is entering $ along with numeric value but for me its something really big. i would never be able to find this. i have been waiting for one month and i was stuck at this point. amazing. thanks from my heart bro. jim. i am a beginner. i am learning myself. no teacher no proper guide line. can u give me some tips. or can i add u in facebook or can i get your email address. thanks again. arif
