I tried to include as many concepts as possible keeping in mind the difficulty level matched the level of the interview questions. Click here to check out 10 java programs for technical interview. Swap two numbers without using a temporary variable Now there are a number of ways you can do this program but there is one way you can really impress the interviewer which uses this cool technique using bitwise operators.

What is XOR gate? Show some other ways to do the swapping. Or you can multiply and then divide. Often you might make a very simple mistake which the interviewer was actually looking for.

If you are still having problems you can visit my post on patterns. Finding the nth Fibonacci number using recursion There are two rules in recursion: The function must have a recursive definition or in simple words can be expressed in its own form.

There is a terminating value for which we know the return value of the function. We have to make a function fibonacci in a recursive form. Can we use this function to print the whole Fibonacci series?

What if we pass a negative number to the fibonacci? Take some rest and come back later but if u want a challenge then continue. Now what is an Armstrong number? If a number has n digits and the sum of the nth power of its digits is the number itself then the number is an Armstrong number.

Surely you got confused. Here are some examples to help you out. The code is given below.

Feel free to peek. Is 0 an Armstrong number? How many 2 digit numbers are Armstrong numbers? Concatenate two strings without using strcat We are so used to using strcat when it comes to concatenate two strings but how can we do that without using strcat?

To answer that you have to know what is string in C and how it is printed. Strings in C are represented by character arrays. The end of the string is marked by a special character known as the null character. So to concatenate two strings you just have to add the characters of the second character array after the first and place a null character at the end.

The code is as follows: Use scanf instead of gets to find the difference. Sort elements of an array using pointers selection sort technique Sorting is a one of the most favorite topic asked during the interviews. It is usually accompanied by something or the other like here sorting is done indirectly using pointers.

There are many sorting techniques but usually bubble sort or selection sort is asked. Sorting the elements of the array using pointers makes the program a bit challenging. If there is an integer array arr[], arr is a pointer which stores the address of the first element of arr[]. Using this knowledge you can start writing the program.

What is the bubble sort technique? What are the other sorting techniques that are asked during the interviews? Enter and print details of n employees using structures and dynamic memory allocation This program is used to show the most basic use of structures.
