Codingal Interview Questions and Answers
11 Interview questions
In Python, the expression 3 + 2 * 2 evaluates to 7 due to operator precedence.
Python follows the order of operations: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
In the expression 3 + 2 * 2, multiplication is performed before addition.
So, 2 * 2 equals 4, and then 3 + 4 equals 7.
You can verify this in Python by running: print(3 + 2 * 2) whi...

Constructor is used to initialize an object when it is created, while destructor is used to clean up resources when an object is destroyed.
Constructor is called when an object is created, while destructor is called when an object is destroyed.
Constructors can have parameters to initialize the object, while destructors do not take any parameters.
Example: Constructor initializes member variables of a class, while de...

A data structure is a way of organizing and storing data in a computer so that it can be accessed and manipulated efficiently.
Data structures provide a means to manage and organize data effectively.
They define the relationship between data elements and enable operations to be performed on the data.
Examples of data structures include arrays, linked lists, stacks, queues, trees, and graphs.
Conditional statements are used to execute certain code based on a specific condition being met.
Conditional statements are often written using if/else statements
The condition is placed inside the parentheses after the if keyword
If the condition is true, the code inside the if block is executed, otherwise the code inside the else block is executed
Example: if(x > 5) {do something} else {do something else}
I am comfortable with Java, Python, and C++.
Proficient in Java with experience in developing web applications using Spring framework
Skilled in Python for data analysis and machine learning projects
Familiar with C++ for competitive programming and algorithm development
Loops, arrays, and conditional statements are fundamental programming concepts.
Loops allow for repetitive execution of code based on a condition or a set number of iterations.
Arrays are collections of data that can be accessed and manipulated using an index.
Conditional statements allow for the execution of different code based on a specified condition.
Examples: for loop, while loop, do-while loop, if statement, sw...
Switch is a control statement used to select one of many code blocks to be executed.
Switch statement evaluates an expression and compares it with multiple cases
If a match is found, the code block associated with that case is executed
If no match is found, the default code block is executed
Example: switch(expression) { case 1: //code block; break; case 2: //code block; break; default: //code block; }
