A toy company manufactures electronic learning boards for kids to learn alphabets. Accordingly,

when a kid presses 1 alphabet a is shown on the screen, and when 2 is pressed ab is shown along

with the previous alphabet and so on. The patterns are likely to be as follow:

a

ab

abc

abcd

abcde

Develop a C-script which generates the above-mentioned pattern.

Develop a program that asks user to enter a real number. After entering the numbers, the program

should display how many positive, negatives, and zeros were entered by the user. In addition to

that, it should provide information about the majority count either of the entered numbers.

Note : use any loop and avoid to use arrays .

What will the value of the answer variable be after the code segment below has been run.

int answer ;  

int number1 = 285, number6 = 46, number11 = 1;  

answer = ( number1 % number6 ) / number11;  

I have a problem with a coding assignment and am becoming clueless as to how to solve it.

I am working with PGM images and I have read the data and saved it into a buffer (2D array ex. data[width][height])

I have been asked to then transfer that data into an array of 2d arrays of size 8x8 for the 2d arrays and the number of arrays is width*height/64.

How would I go about storing the data from the 2D buffer into the array of 8x8 2D arrays?

Write a program to take as input an array of N names, an array of N ids and an array of N salaries where the name, id, and salary of the 𝑖 th index belongs to the same person. Store them in a structure and sort them according to salaries (ascending) and then by ids (ascending). Print the person in the sorted order.

Sample input:

5

Mr. Kamal

Ms. Zara

Nitu Roy

Rakib Hasan

Samira Haque 32 28 29 25 30

165 163 165 178 165

Sample output :

Ms. Zara 163 28

Nitu Roy 165 29

Samira Haque 165 30

Mr. Kamal 165 32

Rakib Hasan 178 25

2. Vishal is having a bunch of coins ranging from rupees 1 to 10. Help him to write program to find the sum and average of the coins that he is having using while loop.

Solution: 

Write a program to implement the Merge sort algorithm with the space optimization for

auxiliary space O(n/2).

Write a program for Linked-list implementation of a complete binary tree. The program must

have the following functionalities.

a) Insert(): inserts a new ITEM to the complete binary tree. The items are of integer type.

b) Height(): returns height of a node recursively. Height (N) = MAX(Height(L), Height(R))

+ 1. Here, L and R respectively represent the Left child and Right child of node N. Height

of a leaf node is 0.

c) Preorder(): returns the preorder traversal sequence of the binary tree. Use recursive

implementation.

d) Postorder(): returns the postorder traversal sequence of the binary tree. Use recursive

implementation.

6. Integer Pairing

by CodeChum Admin

Now this one's a tad bit tricky, but you can definitely do it!

Instructions:

1. Input five integers.
2. Add the 1st and 2nd integers together and store the sum inside a variable.
3. Add the 3rd and 4th integers together and store the sum inside a variable.
4. Multiply the two sums and raise the product result to the power of the 5th integer.
5. Print out the result.

Input

1. First integer

2. Second integer

3. Third integer

4. Fourth integer

5. Fifth integer

Output

The first five lines will contain message prompts to input the five integers.

The line contains the result.

Enter·integer·1:·2
Enter·integer·2:·3
Enter·integer·3:·3
Enter·integer·4:·5
Enter·integer·5:·4
Result·=·2560000
