Stryker Software Developer Interview Questions and Answers

Reverse an integer

• Convert integer to string and reverse the string

• Use modulo operator to extract digits and reverse them

• Use recursion to reverse the integer

Print 1 to 10 without using loops.

• Use recursion to print numbers.

• Use a switch statement to print numbers.

• Use an array and map function to print numbers.

Reverse a string using recursion

• Create a function that takes a string as input

• If the string is empty, return an empty string

• Otherwise, call the function recursively with the substring starting from the second character

• Concatenate the first character with the result of the recursive call

Thread is a lightweight unit of a process. Process is an instance of a program that runs independently.

• Threads share the same memory space as the parent process while processes have their own memory space.

• Threads are faster to create and switch between than processes.

• Processes are more secure and stable than threads.

• Example: A web server can have multiple threads to handle multiple requests simultaneously.

• Example: A wo...read more

SPI and I2C are communication protocols used to transfer data between devices.

• SPI is faster than I2C.

• SPI uses separate lines for data and clock signals while I2C uses a shared line.

• I2C supports multiple devices on the same bus while SPI requires a separate chip select line for each device.

• SPI is commonly used for high-speed communication between microcontrollers and peripherals while I2C is used for low-speed communica...read more

The start condition for SPI is a low-to-high transition on the SCK line while SS is high.

• SPI communication begins when the master device sends a start condition to the slave device.

• The start condition is a low-to-high transition on the SCK line while SS is high.

• The SS line is used to select the slave device for communication.

• The SPI protocol supports multiple slaves, but only one slave can be selected at a time.

• After t...read more

• Declare an array of strings to store EMP ID, name, and salary

• Use cin to take input from user and store in the array

• Use cout to display the stored data
