How do I handle the possible exceptions and how do I communicate between.

LINQ Help

bool IsSmooth(string input)
{
    var inputWords = input.Split();

    bool allCharsMatch = true;
    for (int i = 1; i < inputWords.Length; i++)
    {
        if (inputWords[i][0] != inputWords[i - 1].Last()) 
        {
            allCharsMatch = false;
            break;
        }
    }
    return allCharsMatch;
}

bool IsSmooth(string input)
{
    var inputWords = input.Split();

    bool allCharsMatch = true;
    for (int i = 1; i < inputWords.Length; i++)
    {
        if (inputWords[i][0] != inputWords[i - 1].Last()) 
        {
            allCharsMatch = false;
            break;
        }
    }
    return allCharsMatch;
}

How can I get the same functionality with LINQ, I tried looking it up but its usage of lambda functions confused me. Should I stick with this type of loops instead of LINQ and where can I learn LINQ, Microsoft's LINQ documentation is too complex for me. If I need to spend more time before I get into LINQ what should I accomplish / know?

Confused about if statements

int sumPos = 0;
int sumNeg = 0;
bool isEmpty = false;
if (input is [])
{
    Console.WriteLine("[] you entered an empty array");
    isEmpty = true;
}
else //the line I talk about when I add else if(isEmpty = false)
{
    Debug.WriteLine("isEmpty = false");
    foreach (int i in input)
    {
        if (i > 0)
        {
            sumPos += i;
        }
        else if (i < 0)
        {
            sumNeg += i;
        }
    }
    Console.WriteLine("Sum of the positives: " + sumPos + "\nSum of the negatives: " + sumNeg);
}

int sumPos = 0;
int sumNeg = 0;
bool isEmpty = false;
if (input is [])
{
    Console.WriteLine("[] you entered an empty array");
    isEmpty = true;
}
else //the line I talk about when I add else if(isEmpty = false)
{
    Debug.WriteLine("isEmpty = false");
    foreach (int i in input)
    {
        if (i > 0)
        {
            sumPos += i;
        }
        else if (i < 0)
        {
            sumNeg += i;
        }
    }
    Console.WriteLine("Sum of the positives: " + sumPos + "\nSum of the negatives: " + sumNeg);
}

when I add else if instead of else the condition is met even in the debugging but it skips the else if statement

Method generated Array printing.

int[] ArrayGenerator(int number, int length)
{
    int[] returnArray = new int[length];
    for (int i = 0; i < length; i++)
    {
        if (i > 0)
        {
            int result = i * number;
            returnArray[i] = result;
            
        }
        else
        {
            returnArray[i] = number;
            
        }
    }
    return returnArray;
}

int[] ArrayGenerator(int number, int length)
{
    int[] returnArray = new int[length];
    for (int i = 0; i < length; i++)
    {
        if (i > 0)
        {
            int result = i * number;
            returnArray[i] = result;
            
        }
        else
        {
            returnArray[i] = number;
            
        }
    }
    return returnArray;
}

How can I print the array this function returns and is the code problematic?

if statement and scopes

A developer writes some code that includes an if statement code block. They initialize one integer variable to a value of 5 above (outside) of the code block. They initialize a second integer variable to a value of 6 on the first line inside of the code block. The Boolean expression for the code block evaluates to true if the first integer variable has a value greater than 0. On the second line inside the code block, they assign the sum of the two values to the first variable. On the first line after the code block, they write code to display the value of the first integer. What is the result when the code statement used to display the first integer is executed? I try to write this code in my IDE to answer the question although while I'm getting an error the answer is that the program runs without errors just displays the wrong value. Here is my code: static void Main() { int x = 5; if (x > 0) { int y = 6; int x = x + y; } Console.Read(); } I get the errors: Error CS0136 A local or parameter named 'x' cannot be declared in this scope because that name is used in an enclosing local scope to define a local or parameter Use of unassigned local variable 'x'
