Introduction to Visual Basic Class 8 MCQ with Answers and Explanations:
1.) The instructions that tells the computer to perform the task in relation to conversion of data into the meaningful information.
a) Computer guide b) Computer helper c) Computer program d) None of these
Explanation :- Computer program in the program that helps/ tells the computer in completing the tasks that are in relation to converting of data into a meaningful information.
2.) The person who writes such type of programs is known as
a) Content creator b) Author c) Youtuber d) Programmer
Explanation :- Programming language is a language used to write the program by making use of words, symbols and codes. Visual Basic is the example of the programming language. the way of writing this instructions is called as programs and the person who writes this computer programs are termed as programmers.
3.) The method that is only used to communicate between the user and the computer.
a) Programming language b) Human language
c) Computer language d) All of these
Explanation :-Computer language is the only way which is used to communicate between the user and the computer system. Computer does not understand the language of human beings but it understands the vocabularies as the signs/symbols in their own languages. At the time of writing this program, these symbols are used as per the rules.
4.) Visual Basic is a programming language from
a) Windows b) Microsoft c) Google d) None of these
Explanation :-VB is the short abbreviation of Visual Basic and is a programming language from the Microsoft. With the help of this language, the programmer not only creates the simple applications but can develop the very complicated applications that is very easy to use. Whatever objective might be, you can create VB program depending upon the objective. For ex:- you can create the educational programs for the study/teaching of the subjects like geography, history, maths, science etc. where as the accounting programs are been created for managing the financial or accounting things and to make the person more efficient in controlling the finance and becoming the good accountant. The programs that is related to games can also be created, but the programmer must make sure that before creating any VB programs, VB must be installed in the computer. VB is a high-level programming language and is the next version of BASIC.
5.) BASIC stands for
a) Begin All Symbols and In coding
b) Beginners All Purpose Symbolic Instruction Code
c) Beginning for All Processing and Solving the Instructional Coding.
d) None of these
Explanation :-BASIC stands for Beginners for All-purpose Instruction Code. In the year 1963,John Kenny and Thomas Kurtz developed the high level programming language (BASIC). If any beginner wants to learn the programming language, then he can learn/ get training of BASIC. GW-BASIC, POWER BASIC, Q BASIC are some of the different versions of BASIC programming language.
6) In VB, it includes the items like buttons, text boxes and labels
a) Instructions b) Menus c) Objects d) event
Explanation :-Firstly you can create the programs in VB by making use of the objects. Buttons, text boxes, labels etc are the items which are included in the VB objects. Dragging of the graphical objects onto the screen with the help of mouse are the simple programming aspects that can be generated by Visual Basic.
7.) It is the action’s result that is initiated by the user
a) Instructions b) Menus c) Objects d) event
Explanation :- In VB, an event is the result of the action that is acted/done by the user. For ex :- When the programmer/user makes a click on Visual Basic button, then the Visual Basic program executes the Click event. The events in the Visual Basic are been created by writing instructions (codes) with its by default and built in programming language.
8.) There are …………. categories of data types in VB.
a) 4 b) 2 c) 6 d) 8
Explanation :- In VB it is much necessary to define the data type for completing various tasks like storing of different types of values such as names, address, large numbers, large numbers etc. The user has to make sure that before working with VB, the user has to inform the VB that exactly what type of data the value is. The two categories of Data Types i.e are Numeric (Byte, Integer, Long integer, Decimal, Single. Double, Currency) and Non- Numeric (String, Boolean, Variant, Object, Date and Time). In VB, basically there are 12 data types.
9.) The series of zero or more characters.
a) Byte b) Boolean c) String d) Decimal
Explanation :- String is a series of zero or more characters. There are numeric characters in the strings but then too they cant be used for calculations work/ mathematical problems. It holds the some data types which can be used for doing calculation works like address, names, codes etc.
10) A real number that displays the decimal part
a) Byte b) Boolean c) String d) Decimal
Explanation :- In VB decimal is a real number that display the decimal part. In this method the numbers can be separated from each other int two sections by making use of symbols like the Decimal separator or decimal symbol.
11) This data type consists of two values i.e is Yes or No.
a) String b) Variant c) Object d) Boolean
Explanation :- In the VB, Boolean consists of only two values for this data. They are True or False which can be generally treated as with Yes or No values. By setting the values to a control property which only accepts the values as True or False like Enabled property value.
12) It is capable of holding any type of data except the strings whose lengths is fixed.
a) String b) Variant c) Object d) Boolean
Explanation :-Variant is capable of holding any type of data except the strings whose lengths is fixed. When the data storage area hold the different kinds of data, we can make use of variant data for various purpose. The data type which you want to keep in more specific data type area can be kept in the/ stored in the variant storage area for temporary basis.
13) A date is a numeric value that represents the number of days that have elapsed since a determined period.
a) Date and Time b) Month and Year c) Hours and minutes d) None of these
Explanation :-A date is a numeric value that represents the number of days that have elapsed since a determined period. A time is a numeric value that represents the number of seconds that have elapsed in a day.
14) The natural positive number that ranges from 0 to 255.
a) Byte b) Integer c) Double d) Long integer
Explanation :- In VB a byte is a small natural positive number that ranges from 0 to 255. The variables of the byte datatype is used for holding a small values like the age of the person, the number of toes that animals have etc.
15.) In VB the statement is used for declaring variables by assigning them a name and a data type.
a) REM b) DIM c) RENAME d) EDIT
Explanation :-DIM statements is used for declaring variables by assigning them a name and a data type. It is needful to declare the variable with the DIM statement.
