HTC Interview Questions, Process, and Tips

Program to compute the sum of squares of numbers from 1 to 10.

• Use a loop to iterate from 1 to 10

• Use pow(a,b) function to calculate the square of each number

• Add the squares to a variable to get the sum

Function to reverse and display a string

• Create a function that takes a string as input

• Use the split() method to convert the string into an array of characters

• Use the reverse() method to reverse the order of the characters in the array

• Use the join() method to convert the array back into a string

• Return the reversed string

Program to implement stack data structure using array of strings

• Declare an array of strings and a variable to keep track of top element

• Implement push function to add element to top of stack

• Implement pop function to remove top element from stack

• Implement peek function to return top element without removing it

A program to get user name and age with specific conditions.

• Use input() function to get user name and age.

• Use isalpha() function to check if name contains only alphabets.

• Use len() function to check if name is more than 6 characters.

• Use if-else statements to check age range.

• Print the name and age if all conditions are met.

COMP1 and COMP2 are two different components with distinct features and functionalities.

• COMP1 is designed for X while COMP2 is designed for Y

• COMP1 has a higher processing speed than COMP2

• COMP2 has a larger storage capacity than COMP1

• COMP1 is more expensive than COMP2

• COMP2 is more energy-efficient than COMP1

File structure is defined in code and declared in the file system.

• File structure is defined in the code of the program that creates or uses the file.

• The file structure is declared in the file system when the file is created or saved.

• The file structure defines the organization of data within the file, such as headers, tables, or records.

• Examples of file structures include CSV, XML, JSON, and binary formats.

• The file stru...read more

Control blocks are used in programming to control the flow of execution. Examples include if-else, for, while, and switch.

• if-else block is used to execute a certain block of code if a condition is true, and another block of code if the condition is false

• for loop is used to execute a block of code a specific number of times

• while loop is used to execute a block of code repeatedly as long as a certain condition is true

• swi...read more

Dynamic call is resolved at runtime while static call is resolved at compile time.

• Dynamic call is used for polymorphism and late binding.

• Static call is faster and more efficient.

• Dynamic call is resolved using virtual tables while static call is resolved using function pointers.

• Example of dynamic call: virtual functions in C++.

• Example of static call: non-virtual functions in C++.

Control tables are used to manage and control data in a database.

• User access control table

• Audit trail control table

• Configuration control table

• Error log control table

FCT stands for Forward Cosine Transform and DCT stands for Discrete Cosine Transform.

• Both are mathematical techniques used in signal processing and image compression.

• FCT is used in audio signal processing while DCT is used in image and video compression.

• DCT is widely used in JPEG image compression.

• Both transforms convert a signal from the time domain to the frequency domain.

TDQ and TSQ are both IBM mainframe data structures, but TDQ is used for temporary storage while TSQ is used for message queuing.

• TDQ stands for Temporary Data Queue and is used for temporary storage of data.

• TSQ stands for Temporary Storage Queue and is used for message queuing.

• TDQ is typically used for short-term storage of data that will be processed immediately.

• TSQ is typically used for longer-term storage of data tha...read more

TDQ and TSQ are both IBM mainframe data structures, but their speed depends on the specific use case.

• TDQ (Transient Data Queue) is faster for small amounts of data and when the data is being processed by a single program.

• TSQ (Temporary Storage Queue) is faster for larger amounts of data and when the data is being shared between multiple programs.

• The speed of both TDQ and TSQ can also be affected by factors such as syst...read more

TDQ and DCT are both data management tools used in different stages of data processing.

• TDQ stands for Test Data Quality and is used to ensure the accuracy and completeness of data before it is loaded into a system.

• DCT stands for Data Conversion Tool and is used to convert data from one format to another.

• TDQ is used in the data validation stage, while DCT is used in the data transformation stage.

• Both tools are important...read more
