Solution

4)

in von neumann model single memory block is connected to both input blocks and output blocks.

5)

int,float , double , short int, long int, long double etc are the various numeric data types in c++
as given three numeric data types are int , long int , long double
so other three numeric data types in c++ are:
1) float
2) double
3) short int

6)

C++ is strongly typed labgiage means we have to declare all the variables inside a c++ program
so the statement is true.

7)

binary representation of character A and C is given as :
A = 0100 0001
C = 0100 0011

decimal of A = 65
decimal of C = 67

we need B and E

so it means that decimal valuys for B = 66
and decimal valuys for B = 69

so binary value of B = 0100 0010
binalry value of E = 0100 0101

8)

symbols for the address and pointers in c++ is given as below:

for address ampersand sign & is used
for pointer difference operator * is used

9)

Three types of control structures available in C++ are:

1) Sequence structure
2) Selection structure
3) Loop structure (repetition)

10)

lines procede by # sign is called Preprocessor directives.
The preprocessor check the code before actual compilation of code begins and resolves all these directives before any code is generated by regular statements.

example of preprocessor directive as given below:

To define preprocessor macros we can use #define as given below:
#define size 9

if we declare int array in program like this

int abc[size];

After the preprocessor has replaced size the code becomes equivalent to:

int abc[9];

11)

basically there are two ways with which we can declare a comment

1)
single line comment :
for single line comment // is used
means comment start with // and continue until the end of the line

2)
multi line comment
for multiline comment /* */ is used.
means comment start with /* and end with */
