List Complexity

Question

I have totally understed the lists but I have one more thing that I need to know before I am down with it
I have created to lists one with string and one with int

The first string name is jack and its value is 2 The Second string name is john and its values is 5 But as result I am taking John's value 2 John's value 5
Jack's value 2 Jack's value 5

How to make the first string to have only one value and the second its own

List<string> NameList = new List<string>();
        Console.WriteLine("Please insert a name ");
        string name = Console.ReadLine();
        NameList.Add(name);

        List<int> answerList = new List<int>();
        Console.WriteLine("Please insert a value");
        int x = int.Parse(Console.ReadLine());
        answerList.Add(x);

        Console.WriteLine("Do you want to calculate more ? (yes/no)");
        string answer = Console.ReadLine();
        answer.Trim();

        bool isYes = true;
        while (isYes)
        {

            if (answer == "yes")
            {
                Console.WriteLine("Please insert another name/value");
                name = Console.ReadLine();
                x = int.Parse(Console.ReadLine());
                NameList.Add(name);
                answerList.Add(x);
                Console.WriteLine("Do you want to calculate more ? (yes/no)");
                answer = Console.ReadLine();
                answer.Trim();
            }
            else if (answer == "no")
            { break; }
        } string are = " are ";
        foreach (var NAME in NameList)
        foreach (var item in answerList)

            Console.WriteLine("The values of " + NAME + are +item);

Answer 1

The problem is here:

foreach (var NAME in NameList)
foreach (var item in answerList)

you are doing a cross join, matching every name in NameList to every value in answerList. You have a few options:

• Create a class that has Name and Value properties and store instances of that class in a single list
• Use the Zip Linq function to line up the lists element-by-element and iterate through the results in a foreach

Other habits to get into now:

• Use consistent, standard capitalization. Use camelCase for variables (e.g. nameList, answerList) and PascalCase for properties (Name, Answer). Use ALL CAPS for constant values

• remember that Trim returns the trimmed string, so answer.Trim() does nothing (it throws away the output of Trim). Use answer = answer.Trim() instead.
