4.18 Password requirements

Websites commonly require a password that satisfies several requirements. Write a program that checks if an input string satisfies the following (error message is shown for each):

At least 8 characters (Too short)
At least one letter (Missing letter)
At least one number (Missing number)
At least one of these special characters: !, #, % (Missing special)

Output OK, or all related error messages (in above order). If the input string is "Hello", the output is:

Too short Missing number Missing special

Hints:

Declare a boolean variable for each requirement.
Use a for loop to visit each character, setting the corresponding boolean to true if satisfied (length is done differently though).
Use the functions Character.isLetter() and Character.isDigit() to detect if a character is a letter or a number.

Python 3.7.4 Given that add, a function that expects two int parameters and returns their sum, and given that two variables, euro_sales and asia_sales, have already been defined: Write a statement that calls add to compute the sum of euro_sales and asia_sales and that associates this value with a variable named eurasia_sales.
4.19 C++ Write a program that takes in a line of text as input, and outputs that line of text in reverse. The program repeats, ending when the user enters "Done", "done", or "d" for the line of text. Ex: If the input is: Hello there Hey done then the output is: ereht olleH yeH
5.23 In Python: Write a program with total change amount as an integer input that outputs the change using the fewest coins, one coin type per line. The coin types are dollars, quarters, dimes, nickels, and pennies. Use singular and plural coin names as appropriate, like 1 penny vs. 2 pennies. Ex: If the input is: 0 or less, the output is: no change Ex: If the input is: 45 the output is: 1 quarter 2 dimes Your program must define and call the following function. The function exact_change() should return num_dollars, num_quarters, num_dimes, num_nickels, and num_pennies.def exact_change(user_total)
C++ 10.19 Given a line of text as input, output the number of characters excluding spaces, periods, exclamation points, or commas. Ex: If the input is: Listen, Mr. Jones, calm down. the output is: 21 Note: Account for all characters that aren't spaces, periods, exclamation points, or commas (Ex: "r", "2", "?"). code provided: #include <iostream>#include <string>using namespace std; int main() { string userText; // Add more variables as needed getline(cin, userText); // Gets entire line, including spaces. /* Type your code here. */ return 0;}
21.7 LAB: Login name (Use python) Write a program that creates a login name for a user, given the user's first name, last name, and a four-digit integer as input. Output the login name, which is made up of the first five letters of the last name, followed by the first letter of the first name, and then the last two digits of the number (use the % operator). If the last name has less than five letters, then use all letters of the last name. Ex: If the input is: Michael Jordan 1991 the output is: Your login name: JordaM91 Ex: If the input is: Kanye West 2024 the output is: Your login name: WestK24
10.25 LAB: Quadratic formula Implement the quadratic_formula() function. The function takes 3 arguments, a, b, and c, and computes the two results of the quadratic formula: x1=−b+b2−4ac2a x2=−b−b2−4ac2a The quadratic_formula() function returns the tuple (x1, x2). Ex: When a = 1, b = -5, and c = 6, quadratic_formula() returns (3, 2). Code provided in main.py reads a single input line containing values for a, b, and c, separated by spaces. Each input is converted to a float and passed to the quadratic_formula() function. Ex: If the input is: 2 -3 -77 the output is: Solutions to 2x^2 + -3x + -77 = 0 x1 = 7 x2 = -5.50

11.4.1: Leap year - functions. A year in the modern Gregorian Calendar consists of 365 days. In reality, the earth takes longer to rotate around the sun. To account for the difference in time, every 4 years, a leap year takes place. A leap year is when a year has 366 days: An extra day, February 29th. The requirements for a given year to be a leap year are: 1) The year must be divisible by 4 2) If the year is a century year (1700, 1800, etc.), the year must be evenly divisible by 400 Some example leap years are 1600, 1712, and 2016. Write a program that takes in a year and determines whether that year is a leap year. If the input is 1712, the output is: 1712 is a leap year. If the input is 1913, the output is: 1913 is not a leap year. Your program must define and call a function: Function OutputLeapYear(integer inputYear) returns nothing The function should output whether the input year is a leap year or not.

7. using c++, If c is a character (e.g. char c = ‘a’), then (int) c is a number between 0 and 255 that represents its ascii value of that character (the ascii value of ‘a’ is 97. Appendix B contains the ascii character set; for example, (int) ‘a’ == 97. Write a function that accepts two characters, c1, and c2, determines whether (int) c1 is greater than (int) c2, and then returns the sum of the ascii values of all the characters between c1 and c2.
1(a): Implement the following C function : concatenate the lowest byte of each of two integers. The output should have 0's in the two most significant bytes , followed by the least significant byte of the first then second argument . For example , concatLowBytes (0x12345678 , 0xaabbccdd) 0x000078dd . You may use hexidecimal constants of any size. You should not use binary notation , function calls , loops or conditional statements. Examples : concatLowBytes ( 0x00000011 , 0x00000022)=0x00001122 concatLowBytes (0x12345678 , 0xaabbccdd )= 0x000078dd int concatLowBytes (int x, int y){ }
7.24 LAB: Convert to binary-functions Write a program that takes in a positive integer as input, and outputs a string of 1's and O's representing the integer in binary. For an integer x, the algorithm is As long as x is greater than 0 Output x 2 (remainder is either 0 or 1) x = x // 2 Note: The above algorithm outputs the 0's and 1's in reverse order. You will need to write a second function to reverse the string Ex: If the input is the output is: 110 The program must define and call the following two functions. Define a function named int to reverse_binary() that takes an integer as a parameter and returns a string of 1's and O's representing the integer in binary (in reverse). Define a function named string reverse() that takes an input string as a parameter and returns a string representing the input string in reverse. def int_to_reverse_binary(integer_value) def string reverse(input_string) LAB ACTIVITY 7.24.1: LAB.
