Answer: There are four types of operators in QBASIC. They are Arithmetic Operators, Relational Operators, Logical Operators and Sting Operator. a. Arithmetic Operators. Arithmetic Operators are used to perform mathematical calculations like addition, subtraction, division, multiplication and exponential. :)
Answer:
1 will be stored in result
Explanation:
Given
The lines of code
Required
Determine the value stored in result
The value stored in result is determine by the condition (x<3 && y ==6)
In the first line, the value of x is 2 and the value of y is 6
So: x<3 is true because x = 2 and 2 is less than 3
y == 6 is also true because y = 6 and 6 is equal to 6
So, the condition (x<3 && y ==6) is true and true will be saved in variable result
Because result is a Boolean variable which can only take true or false value
1 represents true
0 represents false
<em>So, 1 will be stored in result</em>
Answer:
A class is like a blueprint of object.
Explanation:
A class defines the kinds of data and the functionality their objects will have.
A class enables you to create your own custom types by grouping together variables of other types, methods and events.
In C#, we can create a class using the class keyword.
Here's a sample program:
using System;
namespace ConsoleApplication
{
public class Test
{
public static void Main()
{
Add a1 = new Add(70, 50);
a1.AddNumbers();
Console.ReadLine();
}
}
class Add
{
private int row;
private int column;
public Add(int r, int c)
{
row = r;
column = c;
}
public void AddNumbers()
{
Console.WriteLine(row+column);
}
}
}
output: 120
Explanation of the program:
I have created a class named Add. Within a class, row and column are two fields and AddNumbers() is a method. We also have constructor to initialize row and column.
In main method, If I need to invoke members of the class, I must create an instance of the class. We can create any number of instances using the single class.IN our program, a1 is the reference variable using which we can invoke members of the class. I invoked function in the class and passed arguments to the constructor while creating an instance.
Those values are assigned to method variables and it operated the addition. Thus the output is 120.
