Napisać funkcję obliczającą funkcję geometryczną w tablicy NxM elementowej z elementów o wartościach parzystych znajdujących się pod główną i ponad przeciwną przekątną.

Write a function that calculates the geometric function in an array NxM elements from the elements with values ​​even located under the main and over the opposite diagonal .

Solution For C Program :

// Napisać funkcję obliczającą funkcję geometryczną w tablicy NxM elementowej z elementów o wartościach parzystych znajdujących się pod główną i ponad przeciwną przekątną.

float average (int tab[N][M])

{

int i,j,iloczyn=1;

for(i=0;i<N;i++)

   for(j=0;j<M;j++)

      if(i>j && i<(N-1)-j && i&1==0)

        iloczyn*=tab[i][j];

return pow(iloczyn, (1/(N*M)));
