Q1. Output of the following code: integer a, b, c; set a = 11, b = 12, c = 10; if (b > 0) b++ else a++ end if for (each b from 0 to 5) a = a + 1 end for print (a + c)
Ans. 
The code sets values for three integers and performs conditional and loop operations to print the sum of two integers.
• The value of 'a' is set to 11, 'b' to 12, and 'c' to 10.

• The 'if' condition checks if 'b' is greater than 0 and increments 'b' if true, else increments 'a'.

• The 'for' loop runs for each value of 'b' from 0 to 5 and increments 'a' by 1.

• The final output is the sum of 'a' and 'c', which is 18.

Q1. What is polymorphism
Ans. 
Polymorphism is the ability of an object to take on many forms.
• Polymorphism allows objects of different classes to be treated as if they are of the same class.

• It is achieved through method overriding and method overloading.

• Examples include method overriding in inheritance and implementing interfaces in Java.

• Polymorphism helps in achieving loose coupling and flexibility in code design.

Q2. What is a singleton pattern
Ans. 
Singleton pattern restricts the instantiation of a class to a single instance and provides a global point of access to it.
• Used when only one instance of a class is required throughout the system

• Ensures that the instance is created only once and provides a global point of access to it

• Commonly used in logging, configuration settings, and database connections

• Implemented by making the constructor private and providing a st...read more

Q3. What is encapsulation
Ans. 
Encapsulation is the process of hiding implementation details and exposing only necessary information.
• Encapsulation is a fundamental concept in object-oriented programming.

• It helps in achieving data abstraction and information hiding.

• It allows for better control over the data and prevents unauthorized access.

• Examples include classes in Java, which encapsulate data and methods within a single unit.

• Encapsulation also hel

Q1. Output of the pseudocode:- #include void main() { int a = 100; printf("%0 %x", a); }
Ans. 
The pseudocode will result in a compilation error due to incorrect printf format specifier.
• The printf function has two format specifiers but only one argument is provided.

• The first format specifier '%0' is incorrect and will result in a compilation error.

• The correct format specifier for printing an integer in hexadecimal format is '%x'.

Q6. Explain the working of Ultrasonic sensor.( in my project)
Ans. 
Ultrasonic sensor emits high frequency sound waves and detects the reflected waves to measure distance.
• Ultrasonic sensor emits sound waves above the range of human hearing

• The sound waves travel through the air and bounce off an object

• The sensor then detects the reflected waves and calculates the distance based on the time taken

• Commonly used in robotics, automotive parking sensors, and distance measurement applications

There were 3 sections in round 1 and all these 3 sections were elimination rounds and this round was done on CoCubes Platform.
First Section was Data Structure Algorithms and Psuedocode.
First section was not that difficult but the time management is important. Questions were easy to solve.
Then after clearing first section, Second section was of verbal ability and this round was also easy and the questions were asked on the comprehension, converting to indirect speech and spotting the error.
After the second round the third round was of Game based aptitude.
There were a total of four games namely motion challenge, inductive-logical thinking, switch challenge and digit challenge.
All the sections were not that difficult to solve
