VXL Instruments Interview Questions and Answers

Input a number and print all odd numbers up to one in decreasing order.

• Create a loop to iterate from the input number down to 1

• Check if the current number is odd before printing it

• Decrement the current number in each iteration

A braking system works by converting kinetic energy into heat energy through friction to slow down or stop a vehicle.

• When the brake pedal is pressed, hydraulic fluid is sent to the brake calipers or drums

• The calipers squeeze the brake pads against the rotor, creating friction and slowing down the vehicle

• In disc brakes, the rotor is attached to the wheel, while in drum brakes, the brake shoes press against the inside of the drum

• The friction between the pads and rotor/drum conv...read more

Use two pointers to swap 0's and 1's in a single pass.

• Initialize two pointers, one at the beginning and one at the end of the array.

• Move the first pointer towards the end and the second pointer towards the beginning, swapping 0's and 1's as needed.

• Continue until the two pointers meet in the middle.

Microcontrollers are integrated circuits designed for specific tasks with built-in memory and peripherals, while microprocessors are general-purpose CPUs without built-in memory or peripherals.

• Microcontrollers are typically used in embedded systems for specific tasks like controlling a microwave oven or a washing machine.

• Microprocessors are used in general-purpose computing devices like laptops, desktops, and servers.

• Microcontrollers have built-in memory and peripherals like ...read more

Mechanical engineers play a crucial role in designing by applying principles of physics and materials science to create functional and efficient products.

• Mechanical engineers work on the structural design of products, ensuring they are strong and durable.

• They also focus on the mechanical systems within a product, such as engines or HVAC systems.

• Mechanical engineers collaborate with other engineers, such as electrical and software engineers, to integrate different components i...read more

Stress is a psychological response to external pressures, while pressure is the external force or demand placed on an individual.

• Stress is the body's response to a perceived threat, while pressure is the external force or demand placed on an individual.

• Stress can be caused by various factors such as work deadlines, relationship issues, or financial problems.

• Pressure can come from external sources like work responsibilities, academic expectations, or societal norms.

• Stress can ...read more
