Certainly! Here is the transcribed content formatted for an educational website:---**Topic: Boolean Variables and Conditional Strings in C++ Programming****Objective:**Learn how to declare a Boolean variable and use conditional logic to validate string input based on specific criteria.**Task:**Declare a Boolean variable named `validPassword`. Use `validPassword` to output "Valid" if `passwordStr` contains at least 4 letters and the length of `passwordStr` is less than or equal to 10. Otherwise, output "Invalid".**Examples:**- If the input is `81v4b53Z2Y`, then the output is: ``` Valid ```- If the input is `wH4q1pK0bL2`, then the output is: ``` Invalid ```**Note:**- The `isalpha()` function checks if a character is a letter. It returns true if the character is a letter and false otherwise. - Example: `isalpha('a')` returns true. - Example: `isalpha('8')` returns false.**C++ Code Sample:**```cpp#include using namespace std;int main() { string passwordStr; /* Additional variable declarations go here */ getline(cin, passwordStr); /* Type your additional code here */ if (validPassword) { cout << "Valid" << endl; } else { cout << "Invalid" << endl; }}```This code snippet demonstrates how to declare a string variable, take user input, and apply conditional logic to determine if the input meets certain criteria. The placeholder comments indicate where additional code should be added to implement the logic for checking the validity of the password according to the task requirements.---This content should help learners understand the concept of Booleans and conditional logic in C++ programming.

Step-1) First, initialize a boolean variable validPass to false.Step-2) Then, taking a password as…

Declare a Boolean variable named valid Password. Use valid Password to output "Valid" if passwordStr contains at least 4 letters and passwordStr's length is less than or equal to 10. Otherwise, output "Invalid". Ex: If the input is 81v4b532YZ, then the output is: Valid Ex: If the input is wH4q1pkøbL2, then the output is: Invalid Note: isalpha() returns true if a character is a letter, and false otherwise. Ex: isalpha('a') returns true. isalpha('8') returns false. 1 #include 2 using namespace std; 3 4 int main() { 5 6 7 8 9 10 11 T 12 13 14 15 } 16 string passwordStr; /* Additional variable declarations go here */ getline (cin, passwordStr); /* Type your additional code here */ if (validPassword) { 869. cout << "Valid" << endl; else { 17 18 } cout << "Invalid" << endl;

X609: Magic Date A magic date is one when written in the following format, the month times the date equals the year e.g. 6/10/60. Write code that figures out if a user entered date is a magic date. The dates must be between 1 - 31, inclusive and the months between 1 - 12, inclusive. Let the user know whether they entered a magic date. If the input parameters are not valid, return false. Examples: magicDate(6, 10, 60) -> true magicDate(50, 12, 600) –> false

Write an expression that will cause the following code to print "Equal" if the value of sensorReading is "close enough" to targetValue. Otherwise, print "Not equal". Hint: Use epsilon value 0.0001. Ex: If targetValue is 0.3333 and sensorReading is (1.0/3.0), output is:Equal #include <iostream>#include <cmath>using namespace std; int main() { double targetValue; double sensorReading; cin >> targetValue; cin >> sensorReading; if (/* Your solution goes here */) { cout << "Equal" << endl; } else { cout << "Not equal" << endl; } return 0;}
