int_to_str

Your mission

Implement a function that converts an integer to its decimal string representation, allocating the result on the heap.

See it in action

int_to_str(0)

Expected result

"0"

Your checklist

For your own tracking. Tests grade your code.

The function takes a single int parameter and returns a heap-allocated, null-terminated string.
Use malloc to allocate the result; the caller is responsible for freeing it.
Handle positive numbers, negative numbers, and zero correctly.
The returned string must contain only the sign (if negative) and decimal digits, no extra characters.

More examples

int_to_str(404)

Expected result

"404"

int_to_str(-2048)

Expected result

"-2048"
