Sa se determine care este elementul minim de sub diagonala principala si suma elementelor de pe diagonala secundara

#include <iostream>
#include <climits>

using namespace std;

int main()
{

    cin >> m >> n;
    for (int i=0; i<n; i++)

                if (a[i][j] < min)

            if (i + j == n - 1) // Diagonala secundara
