How do i pass a multidinensional array through a function

Question

i need to pass a multidinesional array through a function to change it in that function

Answer 1

Use std::array

e.g
#include <iostream>
#include <array>

#define myMultiArray std::array<std::array<int,3>,3>

void edit(myMultiArray& myMulti)
{
for(auto& a : myMulti)
for(auto& b : a)
{
b++;
std::cout << b << std::endl;
}
}

int main() {
myMultiArray a1 {{{1,2,3},{4,5,6},{7,8,9}}};
edit(a1);
return 0;
}

Olin Guerrero For normal 2d arrays you can use this.

void someFunc(int** ptr){
//perform some operations
}

for standard library containers,here's a few examples

void fn(vector<vector<int>>& arr);
void fn(array<array<int,5>5>& arr);
void fn(deque<deque<int>> arr);

Or using templates
template <typename T>
void fn(T& arr);
