float diagonalSum(float MATRIX[6][6], int r, int c)

{

int i,j;

float sum=0;

//We are calculating sum of diagonal elements considering both diagonals

//We are adding intersecting element on two diagonal twice

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

{

for(j=0;j<c;j++)

{

if(i==j) //elements on first diagonal

sum+= MATRIX [i][j];

if((i+j)==(r-1)) // elements on off-diagonal

sum+= MATRIX [i][j];

}

}

return sum;

}
