A NoSQL database environment is, simply put, a non-relational and largely distributed database system that enables rapid, ad-hoc organization and analysis of extremely high-volume, disparate data types. NoSQL databases are sometimes referred to as cloud databases, non-relational databases, Big WIN the ultimate Audiobook experience!

Enterdetails — To input data Display — To display the details of the winner Winner — To return the details of the winner trough the object after comparing the votes received by three candidates.
Answer the questions i to iv based on the following code: Give the size of object ob iii. Name the OOPS concept implemented above and its type. Question-2 2. Write an example illustrating the calls for these functions. Question-3 3. Assuming array A and B are sorted in ascending order and the resultant array C is also required to be in ascending order.
Question-4 4. Then you made a mistake while setting up the path and should follow the instruction above and try it again. Downloading and setting up the text editor You can use the default text editor of Windows Notepad to type in the programs.

Such as keeping track of open and close braces and every element is distinct as they have different colors. No important changes have to be made during the installation. In the next chapter how to use the compiler and text editor will be shown.

The answer of it is same as the program in the in the textbook under 1. Write a program that will print the message I Love Computers And compile and run it on the computer. Now go to the Command Prompt and to the directory where the C source file is saved and then compile the C source file with the gcc.
The C source file can be compiled with the following syntax. Sometimes it will give a warning while compiling some programs in the text book and not compile the program. You can use the w swtich while compiling to bypass the warning.
Now compile the C source file with the syntax given above in the Command Prompt and then execute the output file. If the source file has any errors the program will not compile and the debugger will tell what is the error and in which line is it, So that you can debug it. Else the program will compile successfully and you can then execute the output file to run the program. Chapter 3 Loops Q 6. What will be printed by the following program? The answer of this question can simply be found by compiling and executing the code itself.
But during the examination you wont have that privilege.
So its better to try and work out the output just by reading the code. Write the above program using while loop. In this program the code of the previous program which uses a for loop has to be done using a while loop instead. We have to translate all the expressions of the for loop into a while loop.
The count variable will be set to 0 in its initialization.
The condition is given in the whiles loop expression. The increment to the count variable is made at the end of the while loop. Write the program of question 6 using do while loop. This is similar to the previous question but now instead of re-doing the question 6 using a while loop, this time we have to do is using a do while loop.
Just converting the while loop in the previous answer to a do while loop will do the trick. Write a program to find the sum of positive odd numbers and the product of positive even numbers less than or equal to This one can be done in different ways but Im going to do it purely with loops as we are dealing with loops in this chapter.
There is a problem in this question though. The product that is going to be calculated here is an enormous number around 30 digits long which cannot be stored and represented accurately without some external help in C. The data types cannot hold the full precision but at least they can represent some number without overflowing. Data types long long int and double can be used to represent the result of this program. The long long int data type is not described in the textbook so I am going to use the double data type for this program.
Write two programs that read an integer and print its table in descending order using for loop and while loop. For this question the answer is required using for loop and while loop so two separate programs will be written for this question.
As the table needs to be printed in descending order, I will print it starting from 12 down to 1. Write a program that prints the square of all the numbers from 1 to Number Square 1 2 4 3 9. We have to print the output just as its formatted in the question above. Chapter 4 Choices and Decisions Q 2. Write a program that reads temperature and prints a message as given below. The algorithm is already given in the question that is the temperatures, which will be used as the condition expression for the if conditions.
It is quite similar to the grading program on page Write a program that reads a phrase and prints the number of upper-case and lower-case letters in it. This program can be done by the combining two programs given in this chapter.
The first one is on page 57 at the bottom, which counts the number of characters and words in a phrase. The second one is on page 64 which determines whether the entered character is a vowel or consonant. Write a program that reads three numbers and prints the largest. This program can be done in a number of ways with different algorithms.

Im going to do it in a simple way and just print the largest of the three numbers. If you want to print which variable has the largest value or which variables have equal values or if all variables are equal, then that can be done with different ways but I want to keep the program short and simple and do just what the question says using if-else and else-if constructs.
A class of 35 students took an examination in which marks range from 0 to Write a program which finds a The average marks b The number of students failed marks below 50 c The number of students who scored marks Answer: This program can be done using arrays because we havent studied arrays yet at this point in the textbook.
Thus I will do this program using loops and if conditions only. The marks I entered were 0, 7, 11, 21, 35, 42, 49, 52, 53, 55, 57, 58, 63, 64, 66, 68, 69, 71, 72, 73, 76, 77, 81, 85, 86, 88, 89, 91, 95, 96, 97, 99, , , Write a program that prints all odd positive integers less than skipping those that are exactly divisible by 7.
First make a loop, preferably for loop which only prints positive odd integers less than The loop will be similar to the one used in Chapter 3 Loops Q 9. Then in the loop eliminate all the numbers which are divisible by 7 by using an if condition.

I have not written the code for this and the next program myself but found it on the interwebs as my math sucks lol. I will add the URL of the original source here so that you can read the explanation and different ways of doing the program.
Write a program that reads the coefficients, a, b and c of the quadratic equation and prints the real solutions of x, using the following formula Note that if then there is only one real solution. The program can be found here http: I have made some changes in it to fit the question as we only need to print the real solutions and not the complex ones.Examples of namespaces are built-in names, global names in a module and local names in function invocation Scope: Now we will check if the gcc.
A mapping from names to objects. Write a program that will read names and marks of six subjects of five students from the result. For example, in case you start with long answer questions, complete that section and only then move to short or very short answer section.
