Answer:

Assuming your using the language python, The 'or' operator

Explanation:

To explain this further, or is used in python to describe another condition whether the first one was true or false. Here is a list of what they all briefly mean:

Object-Oriented Programming allows you to create objects with specific characteristics. Ex. you could have a dog class that describes a dogs name and breed. You can make an instance and call it Max with its breed being a golden retriever etc.

----------------------------------------------------------------------------------------------------------------

Procedures independant code that just has simple instructions

----------------------------------------------------------------------------------------------------------------

Functions like object oriented programing but instead of having attributes it is a block of code that does an action. In python, unless the function is called, however, it won't do anything

----------------------------------------------------------------------------------------------------------------

'or' allows someone to give another condition whether the other conditions were True or False.

hope this helped :D

Write a program to have the computer guess at a number between 1 and 20. This program has you, the user choose a number between

ivanzaharov [21]

Answer:

This question is answered using C++ programming language.

#include<iostream>

#include <cstdlib>

#include <ctime>

using namespace std;

int main(){

int num, computerguess;

char response, hl;

cout<<"Choose your number: ";

cin>>num;

srand((unsigned) time(0));

int high = 20; int low = 1; int guess = 0;

computerguess = low + rand() % high;

cout<<"Is it "<<computerguess<<" ?y/n: ";

cin>>response;

while(response == 'n'){

cout<<"Higher or Lower? h/l: ";

cin>>hl;

if(hl == 'h'){ low = computerguess+1; }

else{ high = computerguess-1; }

guess++;

computerguess = low + rand() % high;

cout<<"Is it "<<computerguess<<" ?y/n: ";

cin>>response;

}

cout<<"I got your number of "<<num<<" in "<<guess+1<<" guesses.";

return 0;

}

Explanation:

This declares num (user input) and computerguess as integer

int num, computerguess;

This declares response (which could be yes (y) or no (n) and hl (which represents high or low) as char

char response, hl;

This prompts user for input

cout<<"Choose your number: ";

This gets user input

cin>>num;

This allows the computer be able to generate different random numbers at different intervals

srand((unsigned) time(0));

This declares and initializes the range (high and low) to 20 and 1 respectively. Also, the initial number of guess is declared and initialized to 0

int high = 20; int low = 1; int guess = 0;

Here, the computer take a guess

computerguess = low + rand() % high;

This asks if the computer guess is right

cout<<"Is it "<<computerguess<<" ?y/n: ";

This gets user response (y or n)

cin>>response;

The following iteration is repeated until the computer guess is right

while(response == 'n'){

This asks if computer guess is high or low

cout<<"Higher or Lower? h/l: ";

This gets user response (h or l)

cin>>hl;

If the response is higher, this line gets the lower interval of the range

if(hl == 'h'){ low = computerguess+1; }

If the response is lower, this line gets the upper interval of the range

else{ high = computerguess-1; }

This increments the number of guess by 1

guess++;

Here, the computer take a guess

computerguess = low + rand() % high;

This asks if the computer guess is right

cout<<"Is it "<<computerguess<<" ?y/n: ";

This gets user response (y or n)

cin>>response; }

This prints the statistics of the guess

cout<<"I got your number of "<<num<<" in "<<guess+1<<" guesses.";

Write a recursive function sumSquares(num) that given an integer num, returns the sum of squares of numbers from 1 to num. For e

ValentinkaMS [17]

Answer:

Here is the recursive function sumSquares(num) that takes an integer num as parameter and returns the sum of squares of numbers from 1 to num.

def sumSquares(num):

if(num >= 0): # checks if the value of num is less than or equal to 0

if (num==0): #if value of num is 0

return 0 #returns 0 if value of num is 0

else: #if value of num is greater than 0

return sumSquares(num - 1)+ num * num #recursively calls the sumSquares method to return the sum of squares of numbers from 1 to num

else: # if a user enters a negative num

(print("The number if not positive")) #prints this message

exit() # exits after displaying that number if not positive message

#below print statement is used in order to check the working of the function

print(sumSquares(3)) #calls function and passes value 3 for num

Explanation:

The program works as follows:

The function sumSquares(num) that takes an integer num as parameter and returns the sum of squares of numbers from 1 to num

The first if condition checks if value of num is positive. If this condition evaluates to true then the another if statement inside this if statement is executed which checks if the value of num is 0. If this condition evaluates to true then the program returns 0. However if this condition evaluates to false then the else part executes which has the following statement:

return sumSquares(num - 1) + num * num

For example num = 3

so the above recursive statement works as follows:

sumSquares(3-1) + 3 * 3

sumSquares(2) + 9

Note that the sumSquares() method is called again and the value 2 is passed as num. As 2 is greater than 0. So again the recursive statement executes:

sumSquares(2 - 1) + 2 * 2 + 9

sumSquares(1) + 4 + 9

sumSquares(1) + 13

sumSquare() method is called again and the value 1 is passed as num. As 1 is greater than 0. So again the recursive statement executes:

sumSquares(1 - 1) + 1 * 1 + 13

sumSquares(0) + 1 + 13

sumSquares(0) + 14

sumSquare() method is called again and the value 0 is passed as num

As the value of num=0 So the if (num == 0): condition evaluates to true and the statement returns 0 executes which returns 0:

sumSquares(0) + 14

0 + 14

Hence the output is:

The screenshot of the program along with its output is attached.
