 public int[] Big(int[,] arr)
        {
            for(int i = 0; i < arr.GetLength(0); i++)
            {
                int[] max = new int[arr.GetLength(0)];
                max[i] = arr[i, 0];
                    for(int x = 0; x < arr.GetLength(1); x++)
                {
                    if (max[i] < arr[i, x])
                    {
                        max[i]= arr[i, x];
                    }
                }
            }
            return max;

 public int[] Big(int[,] arr)
        {
            for(int i = 0; i < arr.GetLength(0); i++)
            {
                int[] max = new int[arr.GetLength(0)];
                max[i] = arr[i, 0];
                    for(int x = 0; x < arr.GetLength(1); x++)
                {
                    if (max[i] < arr[i, x])
                    {
                        max[i]= arr[i, x];
                    }
                }
            }
            return max;

Why I can't return the array max? It says " the name 'max' does not exist in the curretn context"

Missing a bracket

Str1ke•2y ago

there is bracket under

TheBoxyBear•2y ago

Also max only exists in the scope of the first for since that's where it's defined

Str1ke•2y ago

its just not seen

TheBoxyBear•2y ago

$scope

MODiX•2y ago

you probably want $scopes

TheBoxyBear•2y ago

$scopes

MODiX•2y ago

scope A {
  thing a;
  scope B {
    thing b;
  }
}

scope A {
  thing a;
  scope B {
    thing b;
  }
}

thing a is available in scope A and scope B thing b is available only in scope B

Str1ke•2y ago

oh if I create it outside the for and then define it inside for

TheBoxyBear•2y ago

Then it will be available to return

Str1ke•2y ago

with the variables? or empty?

TheBoxyBear•2y ago

When you create it inside for, it also creates the array every iteration of the loop You can define it outside and set the value in the loop But then it will be null if the first loop never runs

Str1ke•2y ago

But it will return the value even tho it's defined inside the loop, right?
