3.32 Write a program that requests a positive four-digit integer from digits. You are not allowed to use the string data type operations to do this task. Your pro- gram should simply read the input as an integer and process it as an integer, using standard arithmetic operations (+, , -, 7. %, etc). >>> Enter n: 1234 3. 4

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
SOB 35 - (Block 2 - material covered in Week 13) Write a function that takes a list containing characters and numbers as input (in random orders) and displays as output a string containing the character and a list containing the numbers, e.g., given the lists "("h" 1 2 3 "e" "" 4 5 "'" "o"), your method should output: "hello" and '(1 2 3 4 5 6). Please make sure to test your function and to explain how your code works.
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.

5.28 LAB: Convert to binary - functions Write a program that takes in a positive integer as input, and outputs a string of 1's and 0'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: 6 the output is: 110 Your program must define and call the following two functions. The IntegerToReverseBinary() function should return a string of 1's and 0's representing the integer in binary (in reverse). The ReverseString() function should return a string representing the input string in reverse. string IntegerToReverseBinary(int integerValue)string ReverseString(string userString)
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.
4.18 C++ Write a program whose input is two integers, and whose output is the first integer and subsequent increments of 5 as long as the value is less than or equal to the second integer. End with a newline. Ex: If the input is: -15 10 the output is: -15 -10 -5 0 5 10 Ex: If the second integer is less than the first as in: 20 5 the output is: Second integer can't be less than the first. For coding simplicity, output a space after every integer, including the last.
8.16 (Searching for Substrings) Write a program that inputs a line of text and a search string from the keyboard. Using function strstr, locate the first occurrence of the search string in the line of text, and assign the location to variable searchPtr of type char *. If the search string is found, print the remainder of the line of text beginning with the search string. Then, use strstr again to Locate the next occurrence of the search string in the line of text. If a second occurrence is found, print the remainder of the line of text beginning with the second occurrence. [Hint: The second call to strstr should contain searchPtr + 1 as its first argument.] Solve without using pointers
6.8 In Python, An acronym is a word formed from the initial letters of words in a set phrase. Write a program whose input is a phrase and whose output is an acronym of the input. If a word begins with a lower case letter, don't include that letter in the acronym. Assume there will be at least one upper case letter in the input. Ex: If the input is: Institute of Electrical and Electronics Engineers the output is: IEEE
Fibonacci’s sequence starts with values 1 and 1. The next value in the sequence is formed by summing the previous two values. Thus the third value is 1+1=2, the fourth is 1+2=3, the fifth is 2+3=5, etc. Thus, the sequence is 1, 1, 2, 3, 5, 8, 13, 21, …. Write a code fragment using c++ that obtains a positive integer n from the user and displays the sum of the first n numbers in the Fibonacci sequence. If n is not positive, use cout to print out an error message. Put this code fragment in your main() of your project.
(3) Implement the GetNumOfNonWSCharacters() function. GetNumOfNonWSCharacters() has a constant string as a parameter and returns the number of characters in the string, excluding all whitespace. Call GetNumOfNonWSCharacters() in the PrintMenu() function. Ex: Number of non-whitespace characters: 181
6.26 LAB: Exact change - functions 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) Use Python, please.
3.27 LAB: Login name 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 six letters of the first name, followed by the first letter of the last name, an underscore (_), and then the last digit of the number (use the % operator). If the first name has less than six letters, then use all letters of the first name. Ex: If the input is: Michael Jordan 1991 the output is: Your login name: MichaeJ_1 Ex: If the input is: Nicole Smith 2024 the output is: Your login name: NicoleS_4
