Is there a way to take two int arrays in C++
int * arr1;
int * arr2;
//pretend that in the lines below, we fill these two arrays with different
//int values
and then combine them into one larger array that contains both arrays' values?
Use std::copy
defined in the header <algorithm>
. The args are a pointer to the first element of the input, a pointer to one past the last element of the input, and a pointer to the first element of the output.
( https://en.cppreference.com/w/cpp/algorithm/copy )
int * result = new int[size1 + size2];
std::copy(arr1, arr1 + size1, result);
std::copy(arr2, arr2 + size2, result + size1);
Just suggestion, vector
will do better as a dynamic array rather than pointer
