Poorly Executed Mitosis

by CodeChum Admin

A mitosis program has gone out of hand and now does abnormal cell duplication. Rather than scrapping the project, the researchers decided to observe and predict the cell duplication using a program.

Instructions:

1. In the code editor, you are provided with a main() function that asks the user for the 3 integer inputs required for this program and calls the getResult().
2. This getResult() function has the following details:
3. Return type - int
4. Name - getResult
5. Parameters
6. int - Base integer
7. int - Initial factor
8. int - Number of times to process
9. Description - this is a recursive function which implements the desired behavior explained in the problem description
10. The getResult() function is partially implemented already. Your only task is to add the correct recursive case.

Input

1. Base integer

2. Initial factor

3. Number of times to process

Output

Enter·base·integer:·3
Enter·initial·factor:·2
Enter·number·of·times·to·process:·3
Result·=·54

 I Don't Feel So Good

In order to preserve Spiderman's last words, Mr. Stark wants us to create a program that takes a string and output the string with each proceeding output having one less character until it outputs only one string.

Instructions:

1. In the code editor, you are provided with a main() function that asks the user for a string and passes this string and the size of this string to a function call of the function, preserveString().
2. This preserveString() function has the following description:
3. Return type - void
4. Name - preserveString
5. Parameters
6. The string
7. Length of the string
8. Description - this is a recursive function that prints the string repeatedly. Each time it prints the string, it excludes the last character of the string until only one character is left.
9. This preserveString() function has already been partially implemented. Your only task is to add the recursive case of this function.

Input

1. String to be processed

Output

Enter·string:·Hello!
Hello!
Hello
Hell
Hel
He
H

Slowly But Surely

by CodeChum Admin

In life, good things take time.

Let's make a simple program that mirrors this beautiful idea where we ask the user for two integer inputs. The first one would represent the starting number and the second one would represent the next n integers after it.

For example, if the first number inputted is 2 and the second number inputted is 3, then the output would be 3, 4, 5 because these are the next 3 integers after 2.

Instructions:

1. In the code editor, you are provided with a main() function that asks the user for two integers and calls the slowDisplay() function.
2. This slowDisplay() function is a recursive function which should perform the functionality explained in the problem description above.
3. This function is only partially implemented as it lacks a base case. Your task is to add the base case needed by this recursive function.

Input

1. Starting integer

2. Number of integers

Output

Enter·starting·integer:·2
Enter·how·many·next·integers:·3
3·4·5

A teacher divides her class in different group (gr) sizes according to the

activity they have to do. Write a program to determine the number (nr) of groups as well as the nr of pupils (p) who are left to form a smaller gr. They're 56 in the class.

Program structure:

• Declare 3 int variables nrPupils, nrGroups, and nrLeft. nrPupils is the

nr of ps in a class, nrGroups is the nr of grs the class is divided into, and nrLeft is the nr of ps who're in the remaining smaller gr.

• Assign the value 56 to nrPupils.

• Declare an int variable groupSize that's used by a cin statement to input a value from the keyboard and store the size of the grs the teacher requested. Display a message. E.g. Please enter the size of each gr?

• Write the statement to calculate the nr of grs of size groupSize.

• Write the statement to calculate the nr of ps who're in the remaining smaller gr.

The output of the program must be displayed as follows:

There are 9 grs consisting of 6

pupils There are 3 remaining pupils

Find a good cookbook. Read the instructions for your favourite dish. Write a program to display the recipe on the screen but with a difference. The quantity of each ingredient must be multiplied by a value entered from the keyboard. For example, if the recipe needs 2 cups of flour the output displayed will be something like this Please enter the factor to multiply the ingredients with : 4 Recipe name Ingredients // other ingredients 8 cups flour Method The program has the following structure: • Declare an int variable named mFactor to store the value with which the quantity of each ingredient must be multiplied. • The program must make use of a cin statement to input a value from the keyboard and store it in mFactor. Submit both your program and output.

Write a program in C++ to read a number n and find out the sum of the integers from 1 to

then from 1 to 3, then 1 to 4, and so on and to display the sum of the integers from 1 to

n.

For example, from

1 to 2 = 1

1 to 3 = 3

1 to 4 = 6

1 to 5 = 10

1 to 6 = 18

Develop a small application in C++ that should allow the user of application to enter the receipt number, sender name, sender address, receiver name, receiver address, shipment fee and parcel weight. After getting required information, generate a shipment receipt and show as summary on screen.

Write a program to determine the entered character is an alphabet or number or special character using if – else-if – else.

Instruction: This program read a character value from the user and displays whether it is an alphabet or number or special character, with a suitable message.
