C++ exercise

1. Which header file do you need to include to use typecasting ?

a. stdin.h.
b. ctype.h
c. math.h
d. None.

The correct option is (d)
Explanation:
No explanation found for this Question

2. Which is a valid typecast ?

a. char:a;.
b. a(char);.
c. to(char, a);
d. (char)a;

The correct option is (d)
Explanation:
No explanation found for this Question.

3. Which conversion is not possible?

a. int to float
b. float to int
c. char to float
d. All are possible

The correct option is (d)
Explanation:
No Explanation

4. In C++ what type of operator is a cast operator?

a. Unary
b. Ternary
c. Binary
d. Quaternary

The correct option is (a)
Explanation:
The cast operator is a unary operator which is used to convert one data type into another forcefully.

5. What is the conversion type for reinterpret casting ?

a. Pointer to Variable
b. Pointer to Pointer
c. Variable to Pointer
d. Variable to Variable

The correct option is (b)
Explanation:
Reinterpret casting is used to convert a pointer of any data type to another pointer of any other data type. Additionally, this does not match the datatype of the value and the pointer.

6. const_cast manipulates the constness of an object, either to be set or to be removed ?

a. True
b. False

The correct option is (a)
Explanation:
Explanation not found

7. How many type of conversion are there in c?

a. 1
b. 2
c. 3
d. 4

The correct option is (b)
Explanation:
Basically 2 types of convsersion : Implicit Type Conversion and Explicit Type Conversion.

8. Which conversion also called Automatic Type Conversion?

a. Implicit Type Conversion.
b. Both A and B
c. Explicit Type Conversion
d. None of the above

The correct option is (a)
Explanation:
This type of conversion is usually performed by the compiler when necessary without any commands by the user. Thus it is also called “Automatic Type Conversion”.

9. Which type of conversion is NOT accepted ?

a. From float to char pointer
b. From negative int to char
c. From double to char
d. From char to int

The correct option is (a)
Explanation:
Conversion of a float to pointer type is not allowed.

10. Which of the following typecasting is accepted by C?

a. Narrowing conversions
b. Widening & Narrowing conversions
c. Widening conversions
d. None of the above

The correct option is (b)
Explanation:
Widening & Narrowing conversions following typecasting is accepted by C.
