Building a struct with a function - c

Question

Hello i'm trying to build a function to search a car for a client by client demand.
The structure contains: model,year,price.
the client is asked to enter his demands and then the code calls a function that check if there is a car in the structure that is suitable for him.
I get error for "access violation reading error"
thanks!

typedef struct
{
char model[10];
float price;
int year;
}car;
void findCar(car *arr[], int minYear, float maxPrice, char modelWanted, int carAmount);
int main()
{
int carAmount;
car* arr;
puts("How many cars?");
scanf("%d", &carAmount);
arr = (car*)malloc(carAmount * sizeof(car));
if (arr == NULL)
return -1;
for (int i = 0; i < carAmount; i++)
{
puts("Enter car details, Model, Price,Year");
scanf("%s%f%d",arr[i].model,&arr[i].price,&arr[i].year);
}
char modelWanted[SIZE];
float maxPrice;
int minYear;
puts("Enter wanted model,maximum price and minimum year!");
scanf("%s%f%d", modelWanted, &maxPrice, &minYear);
for (int i = 0; i < carAmount; i++)
printf("Model is: %s, Price is: %.2f, Year is: %d\n", arr[i].model, arr[i].price, arr[i].year);
findCar(&arr, minYear, maxPrice, modelWanted, carAmount);
free(arr);
return 1;
}
void findCar(car *arr[], int minYear, float maxPrice, char modelWanted,int carAmount)
{
int i, counter = 0;
for (i = 0; i < carAmount; i++)
if (((strcmp(arr[i]->model, modelWanted)) == 0) && (arr[i]->year >= minYear) && (arr[i]->price <= maxPrice))
{
printf("Model is: %s, Price is: %.2f, Year is: %d\n", arr[i]->model, arr[i]->price, arr[i]->year);
++counter;
}
printf("We found %d cars for you!", counter);
}

Answer 1

You are passing pointer to array of struct
car *arr[]
so instead of accessing elements by arr[i]->model like you do, you should access them using (*arr)[i].model. The method you uses is for accessing the array of pointers to struct element, but you have pointer to array of struct.
Of course already commented char instead of char* will also cause run time error, but you should have received compiler warning for this.
