can anyone help me know about in what way should I write a program so that it can give the output of the diagonal of 3×3 array??

#include <iostream> int main { int arr[3][3] = { {1, 2, 3}, {4, 5, 6}, {7, 8, 9} }; for (int y = 0; y < 3; y++) { for (int x = 0; x < 3; x++) std::cout << arr[y][x]; std::cout << "\n"; } }

#include <iostream> #include <string> int main() { int x = 0, arr[3][3] = { {1, 2, 3}, {4, 5, 6}, {7, 8, 9} }; for (int y = 0; y < 3; y++) { std::cout << arr[y][x] << "\n" << std::string(" ", x + 1); x++; } } Apologies, misread. This code runs fine when I compile it on Windows (Visual Studio and Code::Blocks). I get the output: 1 5 9 If I tried to compile the code via SoloLearn, the output does not follow any particular pattern like the one I set it to do, which is a bit annoying.

I'm not sure but you won't initialise so many in a for loop :)

it is printing the whole array #Cohen Creber not only the diagonal!
