Given integer values for red, green, and blue, subtract the gray from each value.
Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus
(255, 0, 0) is bright red, (130, 0, 130) is a medium purple,(0,0,0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50,
130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray).
Given values for red, green, and blue, remove the gray part.
Answers
Answer:
Here is the C++ program:
#include <iostream> //to use input output functions
using namespace std; //to identify objects cin cout
int main() { //start of main method
int red,green,blue,smallest; //declare variables to store integer values of red,green, blue and to store the smallest value
cout<<"Enter value for red: "; //prompts user to enter value for red
cin>>red; //reads value for red from user
cout<<"Enter value for green: "; //prompts user to enter value for green
cin>>green; //reads value for green from user
cout<<"Enter value for blue: "; //prompts user to enter value for blue
cin>>blue; //reads value for blue from user
//computes the smallest value
if(red<green && red<blue) //if red value is less than green and blue values
smallest=red; //red is the smallest so assign value of red to smallest
else if(green<blue) //if green value is less than blue value
smallest=green; //green is the smallest so assign value of green to smallest
else //this means blue is the smallest
smallest=blue; //assign value of blue to smallest
//removes gray part by subtracting smallest from rgb
red=red-smallest; //subtract smallest from red
green=green-smallest; //subtract smallest from green
blue=blue-smallest; //subtract smallest from blue
cout<<"red after removing gray part: "<<red<<endl; //displays amount of red after removing gray
cout<<"green after removing gray part: "<<green<<endl; //displays amount of green after removing gray
cout<<"blue after removing gray part: "<<blue<<endl; } //displays amount of blue after removing gray
Explanation:
I will explain the program using an example.
Lets say user enter 130 as value for red, 50 for green and 130 for blue. Sp
red = 130
green = 50
blue = 130
First if condition if(red<green && red<blue) checks if value of red is less than green and blue. Since red=130 so this condition evaluate to false and the program moves to the else if part else if(green<blue) which checks if green is less than blue. This condition evaluates to true as green=50 and blue = 130 so green is less than blue. Hence the body of this else if executes which has the statement: smallest=green; so the smallest it set to green value.
smallest = 50
Now the statement: red=red-smallest; becomes:
red = 130 - 50
red = 80
the statement: green=green-smallest; becomes:
green = 50 - 50
green = 0
the statement: blue=blue-smallest; becomes:
blue = 130 - 50
blue = 80
So the output of the entire program is:
red after removing gray part: 80 green after removing gray part: 0 blue after removing gray part: 80
The screenshot of the program along with its output is attached.

What is spreadsheet?
A spreadsheet is a type of computer program used for organizing, calculating, analyzing, and storing data in tabular form. Spreadsheets were created as digital counterparts to traditional paper accounting spreadsheets.
The data entered into a table's cells is what the program uses to run. Each cell may include text, numeric data, or formula results that automatically calculate and display values based on the contents of neighboring cells.
Users of spreadsheets can change any stored value and watch the changes in calculated values. This enables quick investigation of numerous scenarios without the need for manual recalculation, making the spreadsheet helpful for "what-if" study.

Can a syntax error occur in a block-based code? Why or why not?
Answers
The environment stops two instructions from snapping together if they cannot be combined to form a valid assertion. Via preventing syntax problems in this way, block-based programming environments maintain the practice of writing programs by piecemeal assembly of statements.
Why do syntax errors happen?
When a programmer enters an incorrect line of code, they have made a syntax error. Missing punctuation or misspelled names are the two most common syntax mistakes. In either a compiled or an interpreted programming language, a syntax error prevents the code from running.
The source code contains a syntax error, but the object code does not. A source program is created by a programmer using a word processor or editor and written in high level language.

Create a bash shell script for a number guessing game. Here are the requirements: a. Your program generates a random number between 0 and 128 and keeps asking the user to guess the number until the user guesses it correctly. b. If the user guesses a number that is lower or higher than the number to be guessed then indicate that information to the user as a ‘low guess’ or a ‘high guess’ so that the user can get to the correct guess quicker. c. The program keeps track on number of guesses taken by the user to get to the correct guess. This is user’s score. d. Your program asks user for the name and adds user’s name and the score in a file that keeps track of the scores by various users. e. At the end of the game, the program displays the top 3 scores (lowest 3 scores) along with the name of the users to conclude the game. John 4 Sam 7 Tony 10
Answers
Answer:
Here is the bash shell script:
scorefile="scores_bash"
guess=-1
typeset -i n=0
echo -e "guess.bash - Guess a number between 0 to 128\n"
(( answer = RANDOM % 128 + 0 ))
while (( guess != answer )); do
n=n+1
read -p "Enter guess $n: " guess
if (( guess < answer )); then
echo "Low guesss"
elif (( guess > answer )); then
echo "High guess"
fi
done
echo -e "You guessed the number in $n guesses.\n"
read -p "Enter your name: " name
echo $n $name >> $scorefile
echo -e "\nScores"
sort -n $scorefile
Explanation:
The program creates a scorefile as scores_bash to store the names and scores. Next the program initializes the guess with -1. guess is used to store the guess made by user and n is used to store the number of trials user took to guess the correct number. Next the program prompts the user to: Guess a number between 0 to 128 and generates random numbers from 0 to 128 and store it into answer. Next the while loop keeps repeating until the user guesses the correct number. If the user guess is less than the correct answer then the program displays the message Low guess otherwise displays High guess. When the user guesses the correct number, the loop breaks and the message You guessed the number in $n guesses. is displayed where in place of $n the number of trials user take to guess the number is displayed. Next the user is asked to enter his name.
echo $n $name >> $scorefile statement adds the n which is the user score and name which is the names of user to the score file. sort -n $scorefile sorts the file in ascending order to display the lowest scores. The screenshot of program with its output is attached.
