Programming Puzzles Some companies certainly ask for these puzzles. Specially Microsoft. 1. Write a "Hello World" program in 'C' without using a semicolon. 2. Write a C++ program without using any loop (if, for, while etc) to print numbers from 1 to 100 and 100 to 1; 3. C/C++ : Exchange two numbers without using a temporary variable. 4. C/C++ : Find if the given number is a power of 2. 5. C/C++ : Multiply x by 7 without using multiplication (*) operator. 6. C/C++ : Write a function in different ways that will return f(7) = 4 and f(4) = 7 7. Remove duplicates in array 8. Finding if there is any loop inside linked list. 9. Remove duplicates in an no key access database without using an array 10. Convert (integer) number in binary without loops. 11. Write a program whose printed output is an exact copy of the source. Needless to say, merely echoing the actual source file is not allowed. 12. From a 'pool' of numbers (four '1's, four '2's .... four '6's), each player selects a number and adds it to the total. Once a number is used, it must be removed from the pool. The winner is the person whose number makes the total equal 31 exactly. 13. Given an array (group) of numbers write all the possible sub groups of this group. 2

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
