structure array pointer function help

[BrandNew]

I get weird output when I run this program. It seems the printcars function isn't receiving any of the data from the main() function. I have set up a pointer but assume it's not setup properly.

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

struct car {
	char make[16];
	char model[16];
	int year;
	int miles;
};

void printcars(struct car*);

int main()

{

	struct car myCars[3];
	struct car *ptrMC;

	ptrMC=&myCars[3];

	strcpy(myCars[0].make, "Toyota");
	strcpy(myCars[0].model, "Camry V6XL");
	myCars[0].year=1998;
	myCars[0].miles=196758;

	strcpy(myCars[1].make, "Honda");
	strcpy(myCars[1].model, "Sedan");
	myCars[1].year=2011;
	myCars[1].miles=20;

	strcpy(myCars[2].make, "Toyota");
	strcpy(myCars[2].model, "Sienna");
	myCars[2].year=2006;
	myCars[2].miles=96000;
	
	printcars(ptrMC);
	
}

void printcars(struct car *info)
{
	int x=0;

	for(x=0;x<3;x++){
		printf("make:  %s\n", info[x].make);
		printf("model:  %s\n", info[x].model);
		printf("year:  %d\n", info[x].year);
		printf("miles:  %d\n\n", info[x].miles);
	}
}

ptrMC=&myCars[3];

I think it should be

ptrMC = myCars;

and

void printcars(struct car *info)
{
	int x=0;

	for(x=0;x<3;x++){
		printf("make:  %s\n", info[x].make);
		printf("model:  %s\n", info[x].model);
		printf("year:  %d\n", info[x].year);
		printf("miles:  %d\n\n", info[x].miles);
	}
}

should be

void printcars(const struct car *info, size_t num_elem)
{
	size_t x;

	for(x=0;x<num_elem;x++){
		printf("make:  %s\n", info[x].make);
		printf("model:  %s\n", info[x].model);
		printf("year:  %d\n", info[x].year);
		printf("miles:  %d\n\n", info[x].miles);
	}
}

Thanks

 ptrMC=&myCars[3];

I guess I was pointing to the address of an address and the amount of elements is irrelevant to the pointer.

Thanks

 ptrMC=&myCars[3];

I guess I was pointing to the address of an address and the amount of elements is irrelevant to the pointer.

Actually you were pointing at 1 position past the end of your array...

An array[3] has three elements numbered 0, 1 and 2 ... 3 is out of bounds.
