int max1 = int.MinValue, max2 = int.MinValue;
for (int i = 0; i < arr.Length; i++)
{
if (arr[i]>max1)
max1 = arr[i];
else if (arr[i]>max2 && arr[i]!=max1)
max2 = arr[i];
}

Console.WriteLine(max2);

it not works on 0, 5, 1, 2, 1, 5..
first and second both shows 5 output

[AbhilashYadavSanghsevak]

int max1, max2;
int[] arr = { 12, 30, 32, 85, 80, 90, 98, 78, 74 };

for(int i=0;i<arr.Length; i++)
{
Console.WriteLine(arr[i]);
}
max1 = max2 = arr[0];

for(int i=0; i<arr.Length ; i++) {
if (arr[i]>max1)
{
max2 = max1;
max1 = arr[i];
}
else
{
max2 = arr[i];
}
}
Console.WriteLine("First Largest Number : "+max1);

Console.WriteLine("Second Largest Number : " + max2);
Console.ReadLine();



Sir, I have written this code with reference to this video
the out put should be first one will be 98 and second one will be 90 but it is giving the second output :78
