C#: Create a new list from a given list of integers where each integer value is added to 2 and the result value is multiplied by 5


C# Sharp Basic Algorithm: Exercise-145 with Solution

(Value+2) * 5 for Each Integer

Write a C# Sharp program to create a list from a given list of integers. In this program, each integer value is added to 2 and the resulting value is multiplied by 5.

Sample Solution:

C# Sharp Code:

using System; // Importing the System namespace for basic functionality
using System.Collections.Generic; // Importing the namespace for working with collections
using System.Linq; // Importing the namespace for LINQ operations

namespace exercises // Defining a namespace called 'exercises'
{
    class Program // Defining a class named 'Program'
    {
        static void Main(string[] args) // The entry point of the program
        {            
            // Calling the 'test' method with a new list of integers as input
            List<int> mylist = test(new List<int>(new int[] { 1, 2, 3, 4 }));

            // Displaying elements of 'mylist' in the console
            foreach (var i in mylist)
            {
                Console.Write(i.ToString() + " "); // Output each element followed by a space
            }     
        }                  

        // Method that takes a List of integers and performs a calculation on each element
        public static List<int> test(List<int> nums)
        {
            // Using LINQ to perform an arithmetic operation on each element of 'nums'
            // Multiplying each element by 5 times the sum of the element and 2
            IEnumerable<int> e = nums.Select(x => 5 * (x + 2));

            // Converting the IEnumerable 'e' to a new List and returning it
            return e.ToList();
        }    
    } 
}

Sample Output:

15 20 25 30
