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 <em>ref </em>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
Answer:
B. Which customer most frequently purchases bread.
Explanation:
As per the scenario, the data we are receiving from the sales record of the bakery is :
The date on which the items are sold
Each items name which are sold
The number of each item sold and
The price of each item sold
These data are required to estimate how much the company has earned the profit during a given period of time.
So from the above scenario, there is no data given about the customer i.e customer name, customer number, etc. So there is no chance to track the details of a customer purchase history.
Therefore, the most appropriate answer is option B
