simple program weird result

[nav301]

Hi fellow C programmers,
New to programming in C. The code below works fine showing everything except for tracks. It shows 0 tracks no matter what i put in. Can you tell me whats wrong?

#include <stdio.h>
main(){
       char title[20];
       char artist[10];
       int tracks;
       char type[1];
       int price;
       
       printf("Enter CD Title: \n");
       scanf("%s",title);
      
       printf("Enter Artist Name: \n");
       fflush(stdin);
       scanf("%[^\n]",artist);
       
       printf("Enter number of tracks on CD: \n");
       scanf("%d",&tracks);
       
       printf("Enter 'A' for Album or 'S' for single: \n");
       scanf("%s",type);
       
       printf("Enter CD Price: \n");
       scanf("%d",&price);
       
       printf(" CD Information \n");
       printf("-------------------\n");
       printf(" Title: %s , Artist: %s , Tracks: %d , Album/Single: %s , Price: %d \n",title,artist,tracks,type,price);

       fflush(stdin);
       getchar();
}

Thanks

> fflush(stdin);
This isn't defined - see the FAQ

> char type[1];
You need at least 2 chars to store a string, otherwise you just trash something else.
Which in your case seems to be the int track;

Rather than using scanf, just use fgets() to read a whole line, then use sscanf to extract information from the line.
Then all that need for fflush() and weird scanf usage goes away.

>Can you tell me whats wrong?
Yes. You've discovered a subtle problem with the ordering of your variables and array overflow. When you get here:

scanf("%s",type);

You presumably type 'S' or 'A', right? Well, what actually gets written is 'S' or 'A' to type[0] and 0 to type[1]. However, type doesn't have an index 1, only an index 0. Your compiler happens to store the address of tracks where type[1] would be, so 0 gets written there. Try changing the size of type to 2.

You also have other problems. Please read our programming FAQ for detailed info.

Thanks that helped. I am new to programming so i am learning from VTC video.
