Array Maximum Number Finder

Question

Ok so i have to do this: Stretch #2: Write a loop that iterates through the array named valuesand finds the largest number in the array. Place the value into the variable maximum.

I tired not doing it with a loop, but by :

{


    if values[1] > values[0]
    {
      maximum = values[1]
    }
    else if values[2] > values[1]
    {
        maximum = values[2]

    }
    else if values[3] > values[2]
    {
        maximum = values[3]
    }
    else if values[4] > values[3]
    {
        maximum = values[4]
    }


    }

That didn't work and I don't know what to do.

Your code uses an if - else chain rather than a loop which is pretty long-winded and annoying for a large amount of items.

You're probably looking for this:

var maximum = 0
for aValue in values {
    if aValue > maximum {
       maximum = aValue
    }
}

If the array doesn't contain integer values set the variable maximum to the appropriate type.
