Question 1

Array can be considered as set of elements stored in consecutive memory locations but having __________.
A)Same Data Type
B)Same Scope
C)None of these
D)Different Data Type

Accepted Answer

Arrays are collections of elements that must all be of the same data type, meaning they occupy consecutive memory locations and are accessed using indices.

Question 2

In Array, There is one to one correspondence between set of ________ and set of values.
A)Indices
B)Variables
C)Constants
D)Memory Locations

Accepted Answer

In an array, there is a one-to-one correspondence between the set of indices (or index positions) and the set of values stored in the array. Each value in the array is accessed by its unique index.

Question 3

Smallest element of an array is called as _______.
A)Middle Bound
B)Range
C)Upper Bound
D)Lower Bound

Accepted Answer

The smallest element of an array is referred to as the "Lower Bound." This term is used in various contexts, including sorting and searching algorithms, to denote the minimum value or starting point in a collection of elements.

Question 4

If we have declared an array described below -int arr[6];then which of the following array element is considered as last array element ?
A)arr[6]
B)arr[4]
C)arr[0]
D)arr[5]

Accepted Answer

In an array declared as int arr[6], indexing starts from 0. Therefore, the last element is at index 5, which corresponds to arr[5].

Question 5

Array which is having ____ dimensions is called as 2-D array.
A)3
B)2
C)5
D)4

Accepted Answer

A 2-D array, by definition, has 2 dimensions. It is a matrix consisting of rows and columns, making it two-dimensional.

Question 6

What is maximum dimension that array can have in c programming?
A)2
B)4
C)Theoretically No Limit but practically limit depends on memory
D)3

Accepted Answer

The C standard does not specify a maximum number of dimensions for an array, so theoretically, there is no limit. However, in practice, the limit is determined by the compiler and the amount of memory available.

Question 7

Array with last element 'n' will always have array size equal to _______.
A)n+1
B)n-1
C)n+n
D)n

Accepted Answer

The size of an array is determined by the number of elements it contains, not the value of any particular element. If the last element's index is 'n', considering that array indexing starts at 0, the array must contain 'n+1' elements in total.

Question 8

Array is an example of _______ type memory allocation.
A)Compile Time
B)Run Time
C)none
D)all

Accepted Answer

Arrays are typically allocated at compile time, especially when their size is known beforehand, making them examples of compile-time memory allocation.

Question 9

Array is ______ data type in C Programming language.
A)Custom Data Type
B)Primitive Data Type
C)None of these
D)Derived Data Type

Accepted Answer

Arrays in C are classified as derived data types because they are formed by combining the primitive data types in various ways.

Question 10

A Pointer to a block of memory is considered same as an array.
A)NO
B)YES
C)none
D)all

Accepted Answer

In C/C++, a pointer to a block of memory can be used similarly to an array, as both allow access to a sequence of elements in memory.

Question 11

What will happen if in a C program you assign a value to an array element whose subscript exceeds the size of array?
A)The element will be set to 0.
B)The compiler would report an error.
C)The array size would appropriately grow.
D)The program may crash if some important data gets overwritten.

Accepted Answer

When you assign a value to an array element whose subscript exceeds the size of the array, it results in undefined behavior. This means the program may overwrite some other memory location which could be critical for the program or other programs. This can lead to crashes or unpredictable behavior, but the specific outcome can vary depending on the system and the memory layout at runtime. The compiler typically does not catch such errors because array bounds checking is not performed at compile time in standard C.

Question 12

If you pass an array as an argument to a function, what actually gets passed?
A)Base address of the array
B)Value of elements in array
C)First element of the array
D)Address of the last element of array

Accepted Answer

When you pass an array to a function, what is actually passed is the base address of the array, not the entire array itself or any specific element. This allows the function to access the elements of the array using this base address.

Question 13

Pointer is special kind of variable which is used to store __________ of the variable.
A)Address
B)Value
C)Variable Name
D)Data Type

Accepted Answer

Pointers are used to store the memory address of a variable, not its value, name, or data type.

Question 14

Pointer variable is declared using preceding _________ sign.
A)^
B)*
C)&
D)%

Accepted Answer

The asterisk (*) sign is used to declare a pointer variable in programming languages like C and C++.

Question 15

Address stored in the pointer variable is of type __________.
A)Integer
B)Array
C)Floating
D)Character

Accepted Answer

The address stored in a pointer variable is of type integer because it represents a memory address, which is essentially an integer value indicating a location in memory.

Question 16

Consider the 32 bit compiler. We need to store address of integer variable to integer pointer. What will be the size of integer pointer?
A)10 Bytes
B)4 Bytes
C)2 Bytes
D)6 Bytes

Accepted Answer

The answer of Consider the 32 bit compiler. We need...

Question 17

In order to fetch the address of the variable we write preceding _________ sign before variable name.
A)Asteriks
B)Percent
C)Comma
D)Ampersand

Accepted Answer

To fetch the address of a variable in programming languages like C or C++, the ampersand (&) sign is used before the variable name.

Question 18

What is true about fputs function
A)write to a file
B)takes two parameters
C)requires a file pointer
D)all of above

Accepted Answer

The fputs function writes a string to a file, indeed takes two parameters (the string to write and a file pointer to the file where the string will be written), and requires a file pointer to specify the file. Therefore, all of the statements are true about fputs.

Question 19

Wild pointer in C
A)if pointer is pointing to a memory location from where variable has been deleted
B)if pointer has not been initialized
C)if pointer has not defined properly
D)if pointer pointing to more than one variable

Accepted Answer

A wild pointer in C refers to a pointer that has not been initialized and therefore points to an arbitrary memory location.

Question 20

Any type of modification on the parameter inside the function will reflect in actual variable value can be related to..
A)call by value
B)call by reference
C)both of above
D)none of above

Accepted Answer

In call by reference, modifications made to the parameter inside the function do reflect in the actual variable passed, because the address of the variable is passed, allowing direct access and modification to the original variable's memory space.
