The first riddle would be a baby crawling on all fours, then walking on two legs as an adult, and then walking with two legs and a cane as an elder.

The second riddle would be the letter "E"
End, timE, spacE, Every placE.

I hope this helps :)

What is an Algorithm? (might not be in the chapter text). Give an example.

Rashid [163]

Answer:

The answer to this question is given below in the explanation section.

Explanation:

An algorithm is the list of a finite set of instructions and rules that a computer needs to do to complete a task in order to solve a problem.

In short, an algorithm is a series of instructions that are implemented step by step to solve a problem. For example, you could consider a pizza recipe an algorithm for making a pizza in an everyday life routine. But when you are talking about using algorithms in computation and in mathematics. It means that solving a problem using a series of steps step by step.

For example, your everyday tasks aligned on a google calendar and remind you about your tasks using the alarm, etc- how to implement this using set of instructions and rules- is an algorithm.

Solving a quadratic equation is another example of an algorithm.

Binary search, array sorting are an example of an algorithm in computation. Because these algorithms based on the execution of step-by-step instruction to solve a problem such as sorting a list of numbers etc.

Develop a program that will calculate the area and perimeter of a rectangle. The length and width can be given as constant.(LENG

o-na [289]

Answer:

#include <iostream>

using namespace std;

int main()

{

int length = 8;

int width = 8;

int perimeter = 2*(length + width);

int area = length * width;

cout<<"The perimeter is "<<perimeter<<endl;

cout<<"The area is "<<area<<endl;

return 0;

}

Explanation:

include the library iostream for using the input/output instructions in the c++ programming.

Create the main function and define the variable length and width with values.

Then, use the formula for calculating the perimeter and area of rectangle.

$perimeter = 2*(length + width)$

$area = length * width$

and store in the variables and finally print the output.

Which statement is true?

Alexeev081 [22]

Answer:

Bjarne Stroustrop published the first reference guide for C++

Explanation:

Bjarne Stroustrop is a computer scientist who created the C++ programming language while working at the AT&T Bell laboratory. He also published the first reference guide for the programming language.

In October 1985, the book, The C++ Programming Language, was published. It describes the c++ programming language and was the only documentation and reference guide for the programming language at the time. Newer editions have since been published.

Write a program whose input is a string which contains a character and a phrase, and whose output indicates the number of times

otez555 [7]

Answer:

The program written in python is as follows

def countchr(phrase, char):

count = 0

for i in range(len(phrase)):

if phrase[i] == char:

count = count + 1

return count

phrase = input("Enter a Phrase: ")

char = input("Enter a character: ")

print("Occurence: ",countchr(phrase,char))

Explanation:

To answer this question, I made use of function

This line defines function countchr

def countchr(phrase, char):

This line initializes count to 0

count = 0

This line iterates through each character of input phrase

for i in range(len(phrase)):

This line checks if current character equals input character

if phrase[i] == char:

The count variable is incremented, if the above condition is true

count = count + 1

The total number of occurrence is returned using this line

return count

The main method starts here; This line prompts user for phrase

phrase = input("Enter a Phrase: ")

This line prompts user for a character

char = input("Enter a character: ")

This line prints the number of occurrence of the input charcater in the input phrase

print("Occurence: ",countchr(phrase,char))
