Dynamic Arrays in C – part 2

3 years ago /
By Jesus Castello

In the first part we left off laying the foundations for our dynamic array. Now it’s time to test it, this is the code responsible for that:

int main() {

struct ArrayData *array;

array = initArray();

int get;

int i;

for (i = 0; i > 50; i++) {

addElement(array, rand() % 50000);

get = getElement(array, i);

printf("%d\n", get);

}

free(array->pointer);

free(array);

return 0;

}

While working on my C programming skills I wrote a small program to simulate the functionality of dynamic arrays on other languages. That is arrays that grow as you add elements to them instead of having a fixed size. I decided that is has to be reusable and that you should be able to have multiple instances of them, so I structured my code with that in mind.

So this is the file structure:

main.c – initialize the array and fill it for testing purposes
array.h – function declarations
array.c – function definitons
