c) The value that are assigning to the data
Ans: a) Literal
Q2) Fill in the blanks :-
a) Computer programs are the instructions from a computer.
b) The Visual Basic allows programmers to create simple as well as complex applications.
c) The maximum length for a variable name is 255 characters.
d) The data types can be classified into Numeric and Non-numeric categories.
e) A variant storage area can act as a temporary storage location for any data types.
f) Operators manipulates data by combining or compound result.
Q3) Answer the following questions :-
b) Solution:
i) Computer language :- Computer language is the only way which is sued 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.
ii) Programming language :- It 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.
c) Solution:
The two categories of Data Type are Numeric (Byte, Integer, Long integer, Decimal, Single. Double, Currency) and Non- Numeric (String, Boolean, Variant, Object, Date and Time).
d) Solution:
Ans :- Following are some non-numeric data type :-
i) String :- It 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.
ii) Boolean :- There can be 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.
iii) Variant :- It 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.
iv) Object :- It is anything that you want to make use in the program.
v) Date and Time :- 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.
e) Solution:
DIM statements is sued for declaring variables by assigning them a name and a
data type. It is needful to declare the variable with the DIM statement.
f) Solution:
Arithmetic operators, Conditional operators, logical operators are some of the
different operators used in Visual Basic.
