Arbitrary size integers in C/C++

Question

Question

• Is there a way to create a arbitrary size integer using c/c++?

For example:

int main(void) {
  Int i = Int(3); //3-bit i

Explanation:

You could always try to use integer and float manipulation using arrays. If the number is too big for array initialization, you could use the malloc(); function.

Please Note: This method is not very fast, because we will be allocating memory in the heap. You will also have to write your own mathematical operation functions, because I am not quite sure on how to implement it efficiently. SEE MORE BELOW

How to implement (sort of):

---

#include 
#include 

#define MAX_DIGIT_COUNT 1000

int main()
{
    int* big_num = (int*)malloc(sizeof(int) * MAX_DIGIT_COUNT); //allocate memory
    for(int x; x

Please note: This is just a crude way of implementing arbitrary-sized number support in pure C.
