Before we begin, i am new at programming and C# language, So please bear with me. The problem i am having is to display two individual array values in front of each other like this :

Integer Type : sbyte, byte, short, ushort Real Floating point types : float, double

The Code I have tried is :

string[] VariableTypes = { "Integer Type", "Real Floating Point Types" };

string[] IntergerTypes = { "sbyte", "byte", "short", "ushort" };

for (int i = 0; i <= VariableTypes.Length - 1; i++)
{
    for(int j=0; j<=IntergerTypes.Length - 1; j++)
    {
        Console.Write(IntergerTypes[j] + " ");
    }
    Console.WriteLine(VariableTypes[i] + " : ");
}

Output i am getting :

sbyte byte short ushort Integer Type : sbyte byte short ushort Real Floating Point Types :

string[] VariableTypes = {
  "Integer Type", "Real Floating Point Types" 
};
string[][] NumberTypes = {
  new string[] { "sbyte", "byte", "short", "ushort" },
  new string[] { "float", "double" }
};

for (int i = 0; i < VariableTypes.Length; i++)
{
    Console.Write(VariableTypes[i] + " : ");
    for(int j = 0; j < NumberTypes[i].Length; j++)
    {
        Console.Write(NumberTypes[i][j] + " ");
    }
    Console.WriteLine();
}

8.2.1. Nested Loops for 2D Arrays, 8-2-2: Which of the following would I use to get the value in the third row and second column from a 2D array called nums ? A. nums[3][2] B. nums[2][3] for(int i = 0; i<20; i++) { array[i] = j; } for(int j =0; j<20; j++) { cout<< array[i]; } The nested loop that you created above will do exactly what you described. For each loop of the outer for loop it will execute the full 20 loops of the inner loop. so in total you will execute it 21 * 20 times. Also be careful with your index. You want to start with int i = 0 to i < 20 which loops exactly 20 times.

Here's a short method to achieve this:

string[] VariableTypes = { "Integer Types", "Real Floating Point Types" };
string[] IntegerTypes = { "sbyte", "byte", "short", "ushort" };
string[] RealFloatingPointTypes = { "float", "double" };
Console.WriteLine(String.Concat(VariableTypes[0], " : ", String.Join(", ", IntegerTypes)));
Console.WriteLine(String.Concat(VariableTypes[1], " : ", String.Join(", ", RealFloatingPointTypes)));

Multi-dimensional arrays and nested loops, It is also possible to create arrays with two or more dimensions. on each value of a multi-dimensional array, it is necessary to nest several for loops. entries and print the resulting 3 x 3 matrix to the screen, making use of nested for loops,  Bonus: It is not a god idea to iterate over an array using for for in loop. That's because this expression iterates over the enumerable properties. So for an array you wont get values, you will get the item index. Summary. Looping over arrays is a fundamental language construct. JavaScript has several native ways to iterate an array.

You need another array to hold the values you want to relate to Real Floating Point Types and then conditionally check the variable type to see which integer types are associated with it.

string[] VariableTypes = { "Integer Type", "Real Floating Point Types" };
string[] FloatingPointTypes = { "float", "double" };
string[] IntergerTypes = { "sbyte", "byte", "short", "ushort" };

for (int i = 0; i <= VariableTypes.Length - 1; i++)
{
    Console.WriteLine(VariableTypes[i] + " : ");

    if(VariableTypes[i] == "Integer Type")
    {
        for(int j=0; j<=IntergerTypes.Length - 1; j++)
        {
            Console.Write(IntergerTypes[j] + ", ");
        }
    }
    else
    {
        for(int j=0; j<=FloatingPointTypes.Length - 1; j++)
        {
            Console.Write(FloatingPointTypes[j] + ", ");
        }
    }
}

In my opinion, it would be cleaner do this without the nested loops if all you're wanting is a way to achieve the mentioned output:

string[] FloatingPointTypes = { "float", "double" };
string[] IntergerTypes = { "sbyte", "byte", "short", "ushort" };

Console.WriteLine("Integer Type: " + string.Join(", ", IntergerTypes));
Console.WriteLine("Real Floating Point Types: " + string.Join(", ", FloatingPointTypes));

Additionally, you could utilize a class to make this a bit more streamline for you. See the following:

public class VariableType
{
    public string Name { get; set; }

    public List<string> DataTypes { get; set; }
}

and use this class to achieve your desired outcome via the following:

var variableTypes = new List<VariableType>
{
    new VariableType
    {
        Name = "Integer Types",
        DataTypes = new List<string>{ "sbyte", "byte", "short", "ushort" }
    },
    new VariableType
    {
        Name = "Real Floating Point Types",
        DataTypes = new List<string>{ "float", "double" }
    }
};

foreach(var variableType in variableTypes)
{
    Console.WriteLine(variableType.Name + " : " + string.Join(", ", variableType.DataTypes));
}

How to code nested loops in C#? (With multiple examples) · Kodify, With the extension loop variable we fetch a single element from that array with each pass through the loop. Inside this loop we first print the  Resizing array implementation of a stack of strings. So if students were struggling with nested loops before, this will be a great place to review. This tutorial covers 2d arrays & nested loops in Java. Avoid using nested loops as far as possible In most cases, one can replace nested loops with efficient matrix manipulation.

How to loop over two dimensional array in Java?, You can loop over a two-dimensional array in Java by using two for loops, also Similarly to loop an n-dimensional array you need n loops nested into each other. with integer values and the second time to go through each index and print  In this manner, the two nested loops make row and column variables assume all the possible combinations of two values from 1 to 10. If you still have any uncertainties, try stepping through the program with a debugger. To solve this task, we had to use two nested for loops, which are together called a double loop. Generally speaking, whenever

Display results in one matrix (nested for loops, Learn more about matrix, array MATLAB. No, because of the for loop, it displays each value in the same vector with 5 elements and it prints it out for every  In this video we learn about types of array, how many types, filing of one and two dimensional array using loops and the concept of index value, nested loop #one_dimensional_array #two_dimensional

Java Basics Exercises - Java Programming Tutorial, 6.4 TriangularPattern (nested-loop) 10.5 arrayToString() (Array & Method) The program shall always print “ DONE ” before exiting. Modify the program to find the "sum of the squares" of all the numbers from 1 to 100 , i.e. 1*1 + 2*2 + 3*3​  Arrays and loops. One of the nice things about arrays is that you can use a loop to manipulate each element. When an array is declared, the values of each element are not set to zero automatically. In some cases you want to “re-initialize” the array (which means, setting every element to zero). This can be done like in the example above
