5,052 Pointscan somebody explain what does this mean? "Cannot implicitly convert type int to bool?" Thats what i have in my error
Im trying to compare the my current array value to my preceding one. I use a do while loop and inside that i have an conditional if loop that returns true if the value matches and false if it didn't.
namespace Treehouse.CodeChallenges
{
class SequenceDetector
{
public virtual bool Scan(int[] sequence)
{
return true;
}
}
}
namespace Treehouse.CodeChallenges
{
class RepeatDetector : SequenceDetector
{
public override bool Scan(int[] sequence)
{
int i=1;
int j = i-1;
while(i<10){
if(sequence[i]=sequence[j]){
return true;
}else{
return false;
}
}
}
}
}

On line 11 of RepeatDetector.cs, you have an assignment (single "=") where you probably intended an equality comparison (double "==").
Also, when scanning for a match, you probably don't want that else clause because that will force a return before you have checked all the elements. Instead just return false after the loop is over. You should also compute your "j" value inside the loop, and the loop count should be based on the array size an not a fixed number.

5,052 PointsHi Steven Parker,
Thank you for the guidance, and i want you to know that I gain knowledge on what you pointed out. I didn't just follow the direction, but understand the logic behind it.
I had done the:
however, struggling to code the consideration of array size, can you help me with this last challenge?

231,268 PointsDid you remember to fix your loop count to be based on the array size instead of a fixed number?
If so, show the code as you have it now (remember proper formatting).
