Question 1 a) Use pseudocode to describe an algorithm that counts the number of letters, digits and special characters in a string. Anything between 'a' or 'A' and 'z' or 'Z' is considered a letter, anything between 0 and 9 is considered a digit, while anything else is considered a special character. Input: a string s read from the keyboard, for example s = '3 beautiful days.' Output: letter count / = 13, digit count d = 1, special character count c = 3 For solving this task, consider the string to be an array of characters and do not use any predefined functions that would make this task trivial. b) Show an implementation of the algorithm designed in the language of your choice. You will not be penalised for small syntactical errors. c) Implement an algorithm in the language of choice that counts the occurrence of a digit in a number recursively. Input: a number n read from the keyboard, for example n = 30563323 a digit d the occurrences of which should be counted, for example d = 3 Output: a number c = 4 (i.e., how many of digit d there are in n). For solving this task, consider the string to be an array of characters. You can use any predefined functions in the language of your choice, however their name and number/location of arguments must be accurate.

Using a for Loop Summary In this lab the completed program should print the numbers O through 10, along with their values multiplied by 2 and by 10. You should accomplish this using a for loop instead of a counter- controlled while loop. Instructions 1. Write a for loop that uses the loop control variable to take on the values O through 10. 2. In the body of the loop, multiply the value of the loop control variable by 2 and by 10. 3. Execute the program by clicking the Run button at the bottom of the screen. Is the output the same?

Lab Activity for the students: Exercise 5: Write a program that asks the user to input a letter. The program finds and prints if the letter is uppercase or lowercase. Then, the program asks the user to input a string and get a three-character substring from the beginning of the string. (1 Mark ) Example : If the inputs are 'y' and "Community". Then, the program will print: y is lowercase The substring is: Com

String.ParseInt(m); will convert the integer value of m to a String True False

PYTHON QUESTION Use f-strings and psuedocode program2_1.pyWrite a program that calculates weekly pay, disregarding overtime. Assign an hourly pay rate of 27.50 to a properly named constant (see page 80). Prompt the user to enter the weekly hours worked. The hours might not be an integer. Calculate the weekly pay and display it as currency using an f-string. Currency format means two decimal places and a comma for pay in excess of 1,000ドル.00.

(1) Prompt the user for a string that contains two strings separated by a comma • Examples of strings that can be accepted: • Jill, Allen • Jill, Allen • Jill, Allen Ex: Enter input string: Jill, Allen (2) Print an error message if the input string does not contain a comma. Continue to prompt until a valid string is entered. Note: If the input contains a comma, then assume that the input also contains two strings Ex: Enter input string: Jill Allen Error: No comma in string. Enter input strings ming Fundamentals home> 9.11: LAB: Warm up: Parsing strings Ex: (3) Extract the two words from the input string and remove any spaces. Store the strings in two separate variables and output the strings. Enter input string: Jill, Allen First word: Jill Second word: Allen (4) Using a loop, extend the program to handle multiple lines of input. Continue until the user enters q to quit Ex: Enter input string: Jill, Allen First word: Jill Second word: Allen 0 Enter input string: Golden Monkey , First...

Mad Libs are activities that have a person provide various words, which are then used to complete a short story in unexpected (and hopefully funny) ways. Write a program that takes a string and an integer as input, and outputs a sentence using the input values as shown in the example below. The program repeats until the input string is quit and disregards the integer input that follows. Ex: If the input is: apples 5 shoes 2 quit 0 the output is: Eating 5 apples a day keeps the doctor away. Eating 2 shoes a day keeps the doctor away.

Strings and string manipulation Part A: Building upon an Existing Solution Redesign the solution in the following manner. Ask the user for their name and their email addresses before you display the results of the conversions. When the user enters their email address search the string for the @ symbol. If the symbol is not found, ask the user to re-enter their email address till they get it right. When you display the conversion output to the user, you must include the user’s name in the output. Part B: Write Something New! Write a complete and syntactically correct Python program to solve the following problem: Input a date in numeric format from the user e.g. mm/dd/yy. Examine the month entered by the user, if it is larger than 12 or smaller than 1, issue an error message and ask for input again. Perform similar validation tests for the date and year. Year must be 2015. (Any other year is invalid). In addition, the year must only be two digits long.. Once all input has been...
