C: Why do I get the error code "*** stack smashi´ng detected **: terminated" and how do I solve it?

Question

This is my code (not yet finished), written in C.

#include <stdio.h>
#include <string.h>

    //defining struct for customer management
struct customers {
    char regNumber;     //registration number of the car
    char carBrand;      //brand og the car
    char rimType;       //rim type, aluminum or steel
    char tireType;      //tire type, summer or winter
    int queuePlace;     //place in queue
    int waitTime;       //time till customer is treated
};

    //functions used
void standardStartQueue (char regNumber[12], char carBrand[12], char rimType[9], char tireType[4]);

int main ()
{
    //defining vairables
    
    char regNumber[12], carBrand[12], rimType[9], tireType[4];
    
    //function that imports standard start queue
    standardStartQueue (&regNumber[12], &carBrand[12], &rimType[9], &tireType[4]);
    
    printf("%s %s %s %s", regNumber, carBrand, rimType, tireType);
}

    //function that imports standard start queue
void standardStartQueue (char regNumber[12], char carBrand[12], char rimType[9], char tireType[4])
{
    FILE *fp;
    
    fp = fopen("queue.txt", "r");
    
    fscanf(fp, "%s%s%s%s", regNumber, carBrand, rimType, tireType);
}   

When i run the compiler i get the error code: 

*** stack smashi´ng detected **: terminated

Can someone help me solve this?

Thank you 3000!

Answer 1

standardStartQueue (&regNumber[12], &carBrand[12], &rimType[9], &tireType[4]);

This is wrong. You're supposed to pass a pointer to your buffers, but instead, you pass a pointer to the memory addresses AFTER your buffers.

Correctly it should be

standardStartQueue (&regNumber, &carBrand, &rimType, &tireType);

Disclaimer: I came to this conclusion by looking at your code. You may have further issues, I didn't have the time to run your code.

Good luck! :)
