smashing stack detected program terminated in c

Question

I am getting this error *****smashing stack detected******program terminated .I am not using any buffer.Just reading record by record.Please help me.
Here is my code:

#include <stdio.h>



struct art

{

    char name[30];

    float velocity;

    float min_angle;

    float max_angle;

};

create(char *,float,float,float); */

int main()

{



    // printf("I am starting"); 



    FILE *infile;

    struct art input;



    /*** open the accounts file ***/

    infile = fopen ("artillery.txt","r");

    if (infile == NULL)

    {

         fprintf(stderr, "\nError opening artillery.txt\n\n");

         // exit (1);

    }



    while (fread (&input, sizeof(struct art), 6, infile))

    { 

        printf("%s", input.name);

        printf("%f", input.velocity);

        printf("%f", input.min_angle);

        printf("%f", input.max_angle);              

    }

    return 0;

}

file records are:

canon 1700 30 45

bazooka 80 30 45

tank 2000 33 50

ak-47 715 0 90

pistol9mm 380 0 90

revolver 400 0 90

Answer 1

With this

fread (&input, sizeof(struct art), 6, infile)

you are trying to read 6 records into a variable which is a single struct. To read 6 records, you would need an array of 6 structs

struct art input[6];

But you are reading from a text file anyway, so you cannot read directly into the struct.
