Hello again everyone,
i came on here today to ask a question, how do i write more data to an array? if you dont know what i mean ill explain..

here i am just casually declaring an array..
int a[] = {1, 2, 3, 4, 5};

now.. i want to be able to do this..
int a[] = {};

and then afterwards add them in so what would the code be?

The length of an array must be known at compile time. The length cannot be defined at a later time. If you insist on creating an array at some other point, use DMA. Alternatively, the more preferred way is the std::vector^{[1, Link]}. By the way, the second array declaration is invalid. The compiler won't be able to determine the length of the array.

Damnit, so what do you recon i should do?

Like I said, either use DMA or std::vector. Either one will work, but DMA has its risks. Use DMA if the array will stay the same length, or use std::vector if the array's length will change dynamically.
