TCS Programming Questions 2019 | TCS Programming MCQs

TCS Programming questions (MCQs) are discussed here with solutions. These TCS programming MCQs were asked in the latest TCS drive. So practicing these can help you answer a lot of questions in the TCS drive. Check out latest TCS off campus drive details here.

TCS Programming Questions – Section Details

TCS programming concepts or programming questions section consists of 10 programming MCQs. The time duration of this section is 20 minutes. This means you should answer a question in a maximum of 2 minutes.

The syllabus for this section is as follows.

Programming Concepts:
Iteration, recursion, procedural vs OOp.
C Language: call by value/reference, basic and derived data types, storage class, scope and visibility, basics of pointers, basic header files, library functions, branching and looping, command line arguments, user-defined functions.

Algorithms: 
Basic search algorithms, basic sort algorithms (tree traversal, dynamic programming, etc)

Data Structures:
Array, Stack, Queue, List  (tree, hash table, etc)

TCS Programming Questions – Question Types

TCS has officially released a list of indicative question types asked in TCS Programming Mcqs section. The following are the expected question types for this section.

  • Given a code in C language/pseudo-code, Identify the functionality of the code.
  • Given a code in C language/pseudo-code, identify the bug (syntactic/ semantic) in the code.
  • Conceptual Questions in programming
  • Elementary algorithms based questions
  • Elementary data structures based questions
  • Questions based on basics of C language
  • Basic Concepts behind compiling, linking, OS

TCS Programming Questions with Answers

Note: Coding using Command Line Arguments is not mandatory in TCS exam. However, you may expect some programming MCQs based on command line Arguments. Click here to understand Command Line Arguments better

1)  Eesha was in a wonderland where she saw a treasure trove of seven items of various items (in lakhs) and weights (in kgs) as per the table given below.

Value12108111455
Weight465731012

She wanted to bring back the maximum value of items but she was not able to carry more than 10 kgs. Using dynamic programming, what is the maximum value of the items that she could carry back with her.

Answer: 25

5) Realloc () function is used to:

a) Get back the memory that was released earlier using dree() function
b) Reallocate a file pointer when switching between files

d) Long int

Answer: Big int

7) Eesha wants to implement an image viewer application to view images in a given folder. The application will be able to display an image and will also know what its next and previous images are at any given point of time so that the user can so that the user can view next/previous image by pressing right/left keys on the keyboard. Which data structure is appropriate for Esha to use?

a) Tree
b) Queue
c) Linked list
d) Stack

Answer: Linked list

8) The pseudo code below sorts an array using bubble sort. Here A is the array and the” n” is the number of elements in it. Function swap exchanges the value of 2 given value.
