TCS Programming Questions | TCS MCQs for Practice

TCS programming multiple-choice questions (MCQs) are an essential part of the latest TCS recruitment drive. Practicing these MCQs will help candidates prepare effectively for the exam.

TCS Programming Section – Overview

The TCS programming section consists of 10 MCQs, with a time duration of 20 minutes. This means candidates must answer each question in approximately 2 minutes.

Syllabus Breakdown:

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, user-defined functions.

Algorithms:

  • Basic search and sorting algorithms (tree traversal, dynamic programming, etc.)

Data Structures:

  • Array, Stack, Queue, Linked List, Trees, Hash Tables.

TCS Programming Questions – Question Types

TCS has officially released the types of questions expected in the programming MCQs section:

  • Identifying the functionality of a given C/pseudo-code.
  • Finding syntactic/semantic bugs in the code.
  • Conceptual programming questions.
  • Elementary algorithm-based questions.
  • Data structure-based questions.
  • Basics of C language.
  • Fundamentals of compiling, linking, and OS concepts.
