2d stl array
/*
std::array is 1-dimensional, there is no such thing as a 2-dimensional std::array.
You would simply have to use an inner std::array as the element type of an outer
std::array, eg:
*/
#include <iostream>
#include <array>
int main(){
std::array<std::array<int,5>,4> myarray;
for (int i=0; i<5; i++){
for (int j=0; j<10; j++){
myarray[i].at(j) = j+1;
}
}
}
