Coding interviews test your skills, adaptability to work in an organised working environment, and also your learning abilities. The interview patterns of different companies might be different. Some companies may look for everything that is mentioned earlier while some may only look for specific ones. However, it is really important to know the types of questions that you can expect in these interviews. There may be a little change based on the programming language you select but there are some common questions also. Let’s familiarize ourselves with them so that you will pass in flying colours next time you attend an interview.
Q 1 ) What is the functioning behind computer programming?
Ans- Programming basically means to make the computer work on different tasks based on the instructions given. These instructions can also be mentioned as executable commands built for specific purposes
Q 2) Explain Debugging
Ans- A program may have several errors and debugging is the process by which these errors can be corrected. A detailed check is done on these programs and errors are rectified.
Q 3 ) Mention the types of errors that are common during the execution of the program
Ans- The 3 most common errors that make programmers worry most of the time are 1 ) Syntax errors 2) Runtime errors and 3 ) Logical errors.
Q 4) What is the reason behind Syntax errors?
Ans- Syntax errors occur when you make grammatical violations in the programming language. Syntax errors are identified during the compiling time when the translator translates the program.
Q 5) How does Runtime errors occur?
Ans- Runtime errors occur when an illegal operation is done on the computer. These errors occur during the execution of the program. Programmers will be able to identify this error when the computer stops and a diagnostic message appears on the screen
Are you aspiring for a booming career in IT? If YES, then dive in
Q 6 ) How does the logical error occur?
Ans- This is one of the most difficult errors to spot because the translator will not help you identify this. A wrong logic is the main reason behind the logical error to happen
Q 7 ) Mention Flowchart
Ans- This is a pictorial representation through which the flow of control and data in the algorithm can be easily understood by everyone who is concerned with the programming.
Q 8 ) Mention Algorithm
Ans- The algorithm can be said as the steps that are required to be followed to achieve a specific task. It is extremely important for the Algorithm to be clear, precise, and effective.
Q 9 ) What is meant by “ Maintain and update the program”?
Ans- This term means to make changes or improvements in the program in order to meet the software requirements. This is often made after the installation of the program.
Q 10 ) Mention Reserved words
Ans- Reserved words are those words that have a meaning and purpose that are already fixed. Programmers are not allowed to use these words in any other place other than where they are supposed to be used.
Q 11 ) What do you mean by loops?
Ans- This is a structure that makes a set of statements to repeat until a desired result or criteria is achieved. Different types of loops are 1 ) For… Next Loop, While…Wend Loop
Q 12 ) What is For… Next loop?
Ans- This loop can be used to clearly mention the number of times the loop must be repeated. This is also used to make a set of statements repeat for a specific number of times
Q 13 ) What do you mean by the Nested loop?
Ans- A nested loop is a loop that is within the loop
Q 14 ) What do you mean by Documentation?
Ans- Documentation is the process by which the users are made aware of the program by clearly mentioning the algorithm, coding method, design, and usage. Programmers will be able to modify it whenever necessary.
Q 15 ) What is the other name of a binary form of a target language?
Ans- The other name of the binary form of a target language is binary code
Q 16 ) What are constants?
Ans- Constant is a quantity that has a fixed value or it can also be said as the value of constants cannot be changed
Q 17 ) Mention the two types of constants
Ans- The two types of constants are 1) Numeric constants- consist of integers and String constants – A sequence of alphanumeric characters.
Q 18 ) What are operators?
Ans- These are symbols used to carry out certain timely operations on data. Some common operators are arithmetic, relational, logical, and assignment
Q 19 ) Mention the main purpose of arithmetic operators
Ans- Arithmetic operators are responsible for conducting arithmetic operations on values. They perform this function effectively always
Q 20 ) Mention the purpose of Relational operators
Ans- Relational operators are used to identify whether the values and other associated details are true or false. This is mainly used for the successful comparison between two values.
