Marks Questions
Question: Where does the modulus operator be used?
Answer: Modulus operator is an arithmetic operator. It is a binary operator. It requires two operands to perform its
operation. The symbol % is used for this operator. This operator is used when we want the remainder value after
dividing the two integer values. This operator works only for the integer type values. It does not work for the float or
double type values. Example of modulus operator is 6%4=2.
Question: Write the difference between Relational and Logical Operators.
Answer: Relational and Logical Operator’s are used for testing conditions in control statements. These operators return
true or false value after testing conditions. The common differences between them are given below:
Question: What are Unary Operators?
Answer: These operators are those which reqire one operand to perform their operations. For example: Increment (++) and decrement (–) are the unary operators. Increment operator increase unit value in its operand, while decrement operator decrease unit value in its operand. For example:
if int a=5; than, a++; it will increase the value of variable a from 5 to 6 a–; it will decrease the value of variable a from 5 to 4
Question: Write an example of increment and decrement operator.
Answer: Increment (++) and decrement (–) are the unary operators. Increment operator increase unit value in its
operand, while decrement operator decrease unit value in its operand. For example:
if int a=5;
than, a++; it will increase the value of variable a from 5 to 6
a–; it will decrease the value of variable a from 5 to 4
Question: What is Expression?
OR
What is the use of expression in c language?
Answer: In C Language, expression is like a formula. An expression is a combination of operators and operands.
Operators return result after performing operation on their operands. This result can be used in our program.
Consider the following example:
a=4+5;
in this expression, a,4,5 are the operands while = and + are the operators. Here, + operator returns 9 after adding values 4 and 5. This result will be stored in a using the = operator.
Question: Write the different types of assignment operators.
Answer: Assignment operator is called set equals to operator. It’s symbols is =. It is a binary operator that requires two
operands to perform its operation. This operator is used to store the value in a variable or constant. Consider the
following example:
a=5; In this example, value 5 is stored in variable a.
There are many types of shorthand assignment operators. Following table shows these operators with example:
Question: What are Operands?
Answer: Operands are those values or variables on which operators perform their operations. Combination of operatos
and operands is called Expression. Consider the following example of expression:
a + 5
In this example, variable a and value 5 are operands while + operator will be performed on these opearands.
Other Important -Questions
Question: What are Operators? Explain different types of operators.
Answer: Operators are the symbols used to perform specific operations on their operands. According to the no of operands used with the operator, they can be classified into 3 categories:
Unary Operators: These are those operators which require one operand to perform their operation. For example: ++ (increment), –(decrement), ! (not) operators etc.
Binary Operators: These are those operators which require two operands to perform their operation. For
example: a+b, a*b, a>b, a<b etc. Ternary Operator: There is only one ternary operator in C Language. This operator requires three operands to perform its operation. For example:
operand1 ? operand2 : operand3
Question: What are Arithmetic Operators?
Answer: These operators are used to perform arithmetic calculations. There are 5 arithmetic operators in C language. All these operators are binary operators. Each operator require two operands to perform their operation. Following table shows the details of arithmetic operators with example:
1. What will be the output of the following code?
(i) int ch = 20 cout<<++ch << “\n”<< ch<< “\n” ;
(ii) int ch = 20 cout<< ch+1<< “\n”<< ch<< “\n” ;
2. What will be the result of the following two expressions if i =15 initially?
(i) ++i <= 15
(ii) i++ <= 15
3. Write the corresponding C++ expressions for the following mathematical expressions.
(i) e x-x
(ii) (R+S)4
(iii) 2-4y*(p + q)2
(iv) (A+B)2 + (C+D)4
4. Given the value of a, b and c evaluate the following expression
a = 10, b = 5, c = 11
(a >= b) || (!c == b) && (c < a)
5. Determine the output of the following code segment:
a = 2;
b = ++a cout<< a;
cout<< b;
cout<< a++;
cout<< ++a;
6. What is the difference between num = 10 and num= =10 ?
7. What is the output of the following statement?
Int i = 20
cout<< I << i++ << ++i ;
