Which of the following statements represents the number of columns in a regular two-dimensional array named values?

puteri [66]

Answer:

(a) values[0].length

Explanation:

In programming languages such as Java, an array is a collection of data of the same type. For example, a and b below are an example of an array.

a = {5, 6, 7, 9}

b = {{2,3,4}, {3,5,4}, {6,8,5}, {1,4,6}}

But while a is a one-dimensional array, b is a regular two-dimensional array. A two-dimensional array is typically an array of one-dimensional arrays.

Now, a few thing to note about a two-dimensional array:

(i) The number of rows in a 2-dimensional array is given by;

arrayname.length

For example, to get the number of rows in array b above, we simply write;

b.length which will give 4

(ii) The number of columns in a 2-dimensional array is given by;

arrayname[0].length

This is with an assumption that all rows have same number of columns.

To get the number of columns in array b above, we simply write;

b[0].length which will give 3

Therefore, for a regular two-dimensional array named values, the number of columns is represented by: values[0].length

Write a program that will take an integer and add up each of the number’s digits, count the number of digits in the number, and

Inga [223]

For count digits, you could just convert it to a String and check the length
Sum digits, convert to string then seperate each character with charAt then convert it to numbers in the return statement.
Average digits you can convert it to a String and then convert them back after taking them apart.

Reference variables allow arguments to be passed by ____________.

son4ous [18]

Answer:

Reference

Explanation:

The Reference type variable is such type of variable in C# that holds the reference of memory address instead of value. Examples for reference type are classes, interfaces, delegates and arrays.

We can pass parameters to the method by reference using ref keyword

It’s mandatory to initialize the variable value before we pass it as an argument to the method in c#

For example,

int x = 10; // Variable need to be initialized

Add(ref x); // method call

If you pass parameters by reference in method definition, any changes made to it affect the other variable in method call.

Here's a sample program:

using System;

namespace ConsoleApplication

{

public class Test

{

public static void Main()

{

int i = 10;

Console.WriteLine("i=" + i);

Add(ref i);

Console.WriteLine("i=" + i);

Console.ReadLine();

}

public static void Add( ref int j)

{

j = j + 10;

Console.WriteLine("j="+j);

}

Output:

i=10

j=20

i=20
