Top most basic question for coding interview for freshers

 Hello everyone I am Raushan Ranjan

ow are you?

Let's jump into the topic.

Here you will have bunch of important question that you will need to understand the programming syntax and logic. These questions will let you completely understand the syntax of coding language.

Always remember these question seems easy but you might forget while solving in front of interviewer.

These questions are the most basic one. All you need to just understand the basic of programming logic and implement it.

Why you need to focus on these simple question

 Interviewer will throw these question to you at first, just to check is it worth to take your interview. They don't want to waste their time in that kind of student who don't even know single thing. They will analyze you by this way. Through this they can easily know if you have syntax knowledge of particular language or not. They are not going to ask you if you know coding or not instead they will throw these question to you.

In a simpe manner they are checking that  : -

Are you good in Coding?

 

Here are the list of questions with Hint given:

1. Program to check the largest among three numbers:

   • Compare the first number with the second and third numbers.
   • Use conditional statements (if-else) to determine the largest number.

2. Program to find the factorial of a number:

   • Use a loop to iterate from 1 to the given number.
   • Multiply the numbers in each iteration to calculate the factorial.

3. Program to swap two numbers:

   • Use a temporary variable to store the value of one number.
   • Assign the value of the second number to the first number.
   • Assign the value of the temporary variable to the second number.

4. Program to swap two numbers without an extra variable:

   • Use addition and subtraction operations to swap the numbers.
   • Perform arithmetic operations on the given numbers to exchange their values.

5. Program to find even or odd numbers:

   • Use the modulus operator (%) to find the remainder when dividing the number by 2.
   • If the remainder is 0, the number is even. Otherwise, it is odd.

6. Program to implement the ternary operator:

   • Use the syntax "condition ? expression1 : expression2" to implement the ternary operator.
   • The expression1 is executed if the condition is true, otherwise expression2 is executed.

7. Program to find if a number is prime or not:

   • Use a loop to iterate from 2 to the square root of the given number.
   • Check if the number is divisible by any of the numbers in the iteration.
   • If it is divisible, it is not prime. Otherwise, it is prime.

8. Program to find if a number is Armstrong or not:

   • Break down the given number into its individual digits.
   • Calculate the sum of the cubes of the digits.
   • If the sum is equal to the original number, it is an Armstrong number.

9. Program to check if a string is palindrome or not:

   • Use two pointers, one starting from the beginning and the other from the end of the string.
   • Compare the characters at the corresponding positions of the pointers.
   • If all the characters match, the string is a palindrome.

10. Program to find the first ten Fibonacci digits:

    • Use a loop to generate Fibonacci numbers.
    • Start with two variables initialized to 0 and 1.
    • Calculate the next number by adding the previous two numbers.

11. Program to find the power of a number:

    • Use a loop to multiply the base number repeatedly.
    • The number of iterations will be equal to the exponent.

12. Program to make a calculator:

    • Display a menu of operations to the user (e.g., addition, subtraction, multiplication, division).
    • Take input from the user for the chosen operation and the numbers on which the operation is to be performed.
    • Use conditional statements to perform the selected operation and display the result.

Try these question in your early phase of coding but keep in your mind to understand the logic. There is an alternate solution of just copy paste that is easy way to detroy your thinking logic. 

But if you solve by your own you can be better in these things:

• Sytax understanding
• Programming logic
• End of fear of coding
• Confidant on coding 

Hope this will help you out in your journey of cracking  a placement in good company with better package.I have tried to keep this post simple and effective by not adding spicy words. I have just give you the thing that you only need.
