Learning how to use ASP.NET and Angular
Hello chat, I have a question. Being a beginner this week, approximately how long would it take for me to be efficient in ASP.NET/Angular? Would one estimate that it would take 1-3 months as with regular programming? Also where is the best place to pratice the above without having to rely on youtube/tutorial-hell? Thanks

Where is the letter of the array saved?
Hello everyone, Just a quick question. I understand this code based upon the comments but I am wondering why ans just being incremented has anything to do with the logic in comparing where index i is in the string? 
public class Program {
    public static int CountDs(string str)
    {        //Keeping count of the answer with ans
        int ans = 0;
        //Creating a for-loop to iterate over the string
        for(int i = 0; i < str.Length; i++)
        {
            //If at the str at index i either equals d or D, increment ans by 1
            if(str[i] == 'd' || str[i] == 'D')
            {
                ans++;
            }
        }
        return ans;
    }
}
public class Program {
    public static int CountDs(string str)
    {        //Keeping count of the answer with ans
        int ans = 0;
        //Creating a for-loop to iterate over the string
        for(int i = 0; i < str.Length; i++)
        {
            //If at the str at index i either equals d or D, increment ans by 1
            if(str[i] == 'd' || str[i] == 'D')
            {
                ans++;
            }
        }
        return ans;
    }
}
How does the program know how many D's are in the string if it just increments after coming across a D or a d? Where does it 'keep' the d or D?

Help with this coding problem.
Hello all, can someone diagnois what does it mean by this code stack? 
public class Solution {
    public int[] SortArrayByParityII(int[] nums) {
       int n = Convert.ToInt32(nums);
        if(n % 2 == 0)
        {
            Console.WriteLine(n);
        }
        else
        {
            Console.WriteLine(n);
        }
    }
}
public class Solution {
    public int[] SortArrayByParityII(int[] nums) {
       int n = Convert.ToInt32(nums);
        if(n % 2 == 0)
        {
            Console.WriteLine(n);
        }
        else
        {
            Console.WriteLine(n);
        }
    }
}
The problem is 
Line 2: Char 18: error CS0161: 'Solution.SortArrayByParityII(int[])': not all code paths return a value (in Solution.cs)
Line 2: Char 18: error CS0161: 'Solution.SortArrayByParityII(int[])': not all code paths return a value (in Solution.cs)
I've tried converting the array in the method to an int type but that doesn't work
