Q1. What is oops principles
Ans. 
OOPs principles are a set of guidelines that help in designing and implementing object-oriented programs.
• Encapsulation: Hiding the internal details of an object and exposing only the necessary information.

• Inheritance: Creating new classes from existing ones, inheriting their properties and methods.

• Polymorphism: Ability of objects to take on multiple forms or behaviors.

• Abstraction: Focusing on essential features of an o...read more

Q1. OOP concepts Write a class.
Ans. 
A class representing a car with properties and methods.
• Create a class named Car

• Add properties like make, model, year, color

• Include methods like start(), stop(), accelerate(speed), brake()

• Example: class Car { constructor(make, model, year, color) { this.make = make; this.model = model; this.year = year; this.color = color; } start() { console.log('Car started'); } stop() { console.log('Car stopped'); } accelerate(speed)...read more

Q1. Find the ratio of the radius of the inscribed and circumscribed circles of a square of side length a.
Ans. 
Ratio of radius of inscribed and circumscribed circles of a square of side length a.
• The radius of the inscribed circle is half the length of the side of the square.

• The radius of the circumscribed circle is half the diagonal of the square.

• Ratio of radius of inscribed and circumscribed circles is 1:2.

Q2. Find the coordinates of a point p1 with the distance of it from point p2 and the coordinates p2 and p3, given that all three points are collinear.
Ans. 
To find the coordinates of point p1, use the distance formula and the collinearity of the three points.
• Use the distance formula to find the distance between p1 and p2.

• Use the slope formula to find the slope of the line passing through p2 and p3.

• Use the slope and distance to find the equation of the line passing through p2 and p3.

• Use the equation of the line and the coordinates of p2 to find the coordinates of p1.

Q3. With the coordinates of the four points p1, p2, p3, and p4, where p1, p2, and p3 lie on a circle, find whether p4 lies inside or outside of the circle.
Ans. 
To determine if p4 lies inside or outside the circle with p1, p2, and p3 coordinates.
• Calculate the equation of the circle using p1, p2, and p3 coordinates.

• Check the distance between p4 and the center of the circle.

• If the distance is less than the radius of the circle, p4 lies inside the circle, otherwise outside.

Q1. Find a point is inside a circle or not?
Ans. 
To determine if a point is inside a circle, calculate the distance between the point and the center of the circle and compare it to the radius.
• Calculate the distance between the point and the center of the circle using the distance formula: sqrt((x2-x1)^2 + (y2-y1)^2)

• Compare the calculated distance to the radius of the circle. If the distance is less than the radius, the point is inside the circle.

• For example, if the c...read more

Q2. Bit operations in C language
Ans. 
Bit operations in C language involve manipulating individual bits within a data structure.
• Bitwise AND (&) - sets a bit to 1 only if both input bits are 1

• Bitwise OR (|) - sets a bit to 1 if either input bit is 1

• Bitwise XOR (^) - sets a bit to 1 if the input bits are different

• Bitwise NOT (~) - inverts all bits in a number

• Left shift (<<) - shifts bits to the left by a specified number of positions

• Right shift (>>) - shifts
