C developer Interview Questions

The code was successfully written in HackerRank, which successfully compiled, passed 2/3 test cases and still they rejected candidate with Master Degree in Computer Engineering from US University and 20 years of proven record of writing the same code for many other Wall St. Clients.

Isn’t it true that you should pass 3/3?

They gave me the same test on HackerRank which I did successfully (it passed all test cases). Yet my candidacy was rejected. I used a map container. I couldn't find any container suitable for the job. There may be a better solution which I am was not able to figure out. After reading this post, I am also feeling that they are biased :(

Inheritance polymorphism encapsulation abstraction

Inheritance=Inheritance allows use to define The class from which the new class in herits properties data memberand member function is called vase classs and the new created class is clled derived class syntax class derived classs accesss. // data member and member function of derived classs: Polymorphism In simple words we can define polmorpsism as the ability of a meesage to be displayed in more than one from polymorphism important and basic concept of oops. polymorphism in manily divided in to types 1= compile time polmorphism compile time 1 function overloading 2 opertor overloading template 2=rum time polymorphism 1 function overloading Encapsulation= it is one of the most important feature of oops that used to rapping the data and function in to a single unit. The data of class is not accessible to outside the class 4 =Abstraction is the one of the most important feature of oops which is showing only the essential information to the out side would and hiding the intend details abstraction

40%

Assuming the situation is that 2 cars park in these spots, what is the probably that they park next to one another, then the answer is indeed 40%. There are 20 different possible scenarios (5 spots for the first car to park in, times 4 for the second car). If the first car parks on either end (2/5 chance), then there is a 1/4 chance that the second car will park next to the first. If the first car parks in the middle 3 spots (3/5 chance), there is a 2/4 chance that the second car will park next to the first. The combined probability for the cars parking next to each other is (2/5 * 1/4 + 3/5 * 2/4 = 8/20 = 40%).

do the math

I hate to say it but the program will not compile as written. Try it and see. You get a mess of errors because "<<" gets interpreted as the left shift operator instead of the insert into stream operator. To get it to compile you have to use parenthesis like this: cout << (a&b) << (a|b) << (a&&b) << (a||b); In which case we see that the first and second expressions are the "bitwise and" and "bitwise or" operators while the third and fourth expressions are the "logical and" and "logical or" operators. the result is: 1711

Just look at the syntax and you will know what is wrong.

Could you give more details about your interview, what kind of questions were you asked onsite, how many rounds?

This is one of the most dumb 18th century questions that can be asked. Threads are not same for a VM and the OS. Generally, a VM is allowed a single OS thread. Under such condition, more than one time slice is not possible by multithreading.

not sure why you brought in VM... has nothing to do with the question....

use pointer solution to mark start, end of each word, do not use any additional memory

1) first reverse the entire string in place, which results in the spaces and words being in the right place for the final result, but each word is backwards 2) scan thru the string again and reverse each word in place.
