TCS Programming Test 2019 & 2020 Online MCQ Quiz (PDF)

The exam pattern for the TCS exam is revised regularly. In the recent revision, two more sections are added in the written paper. 

These two sections are

  • Technical MCQ based on C language & Coding (TCS Programming test)
  • Quantitative ability 

In these sections, there are 20 questions that you must answer in 40 minutes. 

  1.  In Technical MCQs, aspirants can get some 2** questions that carry more marks.
  2. There is negative marking in each section. Thus, it would help if you answered the questions with proper care.

Hence, you must practice C questions before the exam. 

Also, there are some other things that you must know before the exam,

  • How many vacancies are there?
  • What is the syllabus?
  • What is the pattern of the exam?
  • You must practice aptitude, reasoning, and English questions to crack the paper.

 

TCS Coding Test 2019 & 2020 Online MCQ Quiz

There is one other section in the TCS exam where the candidates are required to solve a programming question in 20 minutes. This question has to be solved with C programming with the help of an inbuilt compiler.

Essential Rules to follow while answering TCS Coding Questions!

In TCS NQT Exam, you will be given 55 minutes to answer the TCS Coding Questions. On the other hand, in the TCS Ninja NQT, you will be given 30 minutes to answer all the questions. You can take the TCS Coding questions in any of the five programming languages.

  • C
  • C++
  • Java
  • Python
  • Perl

Below are a few crucial things to keep in mind while answering the TCS Coding Questions:

1) Which programming language should a candidate choose to respond to?

The language problem is a fundamental problem that every candidate faces. Every TCS NQT 2020 participant has in his/her mind. Should you use C or C++? Will Java, Perl, or Python give you extra marks?

The answer to this problem is pretty simple. 

You will not get any extra marks or bonus marks based on the programming language you choose to answer in. Moreover, if you make any mistakes by deciding a language that you are not familiar with, the damage will be more substantial. 

So, we genuinely advise you to adhere to the language which you are satisfied with. As long as the output is accurate, the programming language you chose will not be noticed.

 

2) How much coding knowledge does a candidate requires?

You will be content to know that we have a piece of good news for you in this case.

If you are appearing for the TCS Exam and are worried about TCS Coding questions, do not worry because candidates do not require in-depth coding expertise to pass the TCS Coding Questions. The Coding questions will be more likely based on straight and straightforward concepts and will probably be straightforward. You need not bother about algorithms, command-line applications, and data structures. You don’t have to stress about linked lists, stacks, queues, trees, and other tough concepts. That must be a big comfort to you, right?

You are more likely to get questions based on:

  • Questions based on Basic loops such as:
    • For loop questions
    • While loop questions
  • Questions based on Conditional Statements such as:
    • Switch statements questions
    • If-else statement questions

In most cases, you are needed to write or solve the programs based on conditional statements and normal loops conditions consisting of arrays, strings, and much more.

In sum, you have only limited syllabus or topics to prepare for the TCS Coding Questions to excel at the TCS NQT 2020. So, study hard, channelize your energy, and plan your strategy well.

Here are some steps to follow while solving the TCS Coding questions with ease:

  • Understand the question: 

Spend the first 5 minutes to understand the question given to you and comprehend the answer. If your English is not too good, give more time to read your TCS coding question.

  • Read the given Input carefully: 

You might not know how to find the answer, but you know how to take the Input. So, you must read the input values carefully.

  • Crack the Logic: 

You must comprehend how to convert the given data into the answer. By this time, you will have about 20 minutes left. So, use this time sensibly to manifest your coding expertise.

 

TCS coding questions 2019 Solutions

Also, you must practice the following TCS Coding questions for getting selected.
