(PYTHON)
Write a program with a function that takes a string; if the length of a string is even, the functionshould add an asterisk at the beginning of a string; else, the function should add asterisks at the end ofa string. The function, then, capitalizes all letters and returns the new string
The program should let the user enter a string and pass it to the function.
(Python) Write a function that receives a string containing a 32-bit hexadecimal integer. The functionmust return the string’s integer value.

- 2. (Guess the Number) Write a C program that plays the game of "guess the number" as fol- lows: Your program chooses the number to be guessed by selecting an integer at random in the range 1 to 1000. The program then types: 5.32 I have a number between 1 and 1000. Can you guess my number? Please type your first guess. The player then types a first guess. The program responds with one of the following: 1. Excellent! You guessed the number! Would you like to play again (y or n)? 2. Too low. Try again. 3. Too high. Try again. If the player's guess is incorrect, your program should loop until the player finally gets the number right. Your program should keep telling the player Too high or Too low to help the player “zero in" on the correct answer. [Note: The searching technique employed in this problem is called binary search. We'll say more about this in the next problem.]arrow_forwardYou must answer the Problem in C++. (Anagrams) Write a function that checks whether two words are anagrams. Two words are anagrams if they contain the same letters in any order. For example, “silent” and “listen” are anagrams. The header of the function is as follows: bool isAnagram(const string& s1, const string& s2) Write a test program that prompts the user to enter two strings and checks whether they are anagrams. Sample Run 1 Enter a string s1: silent Enter a string s2: listen silent and listen are anagrams Sample Run 2 Enter a string s1: split Enter a string s2: lisp split and lisp are not anagramsarrow_forward1. (Functions with Loop and Branches) Write a C program that uses the function, PrintShampoo Instructions(), with int parameter numCycles, and void return type. If numCycles is less than 1, print "Too few.". Else If more than 4, print "Too many.". Else, print "N: Lather and rinse." for numCycles times, where N is the cycle number, followed by "Done.". End with a new line. [hint: use "for" loop from 1 to numCycles times to get desired display] Example output with input 0: Too few Example output with input 5: Too many Example output with input 4: 1: Lather and rinse. 2: Lather and rinse. 3: Lather and rinse. 4: Lather and rinse. Done. #include /* Your user-defined function goes here */ int main(void) { int user Cycles; scanf("%d", &userCycles); PrintShampoo Instructions (user Cycles); return 0; }arrow_forward
- Write a C++ program then modify for question 4 and 5. Show the steps.arrow_forward(Guess the Number) Write a C program that plays the game of “guess the number” as follows: Your program chooses the number to be guessed by selecting an integer at random in the range1 to 1000. The program then types:I have a number between 1 and 1000.Can you guess my number?Please type your first guess.arrow_forward2. (Functions with C string parameters) Write a program in C that uses the function, MakeSentenceExcited() to replace any period (full stop or comma) with an exclamation point. If the input string is: I told my computer I needed a break. It replied "I am sorry, I'm not programmed for that function." The output will be: I told my computer I needed a break! It replied "I am sorry! I'm not programmed for that function!" Assign a string size of 200 or above. Use "fgets()" to take the string input. Don't forget to include the string header file. Hint: A very similar example 3 problem is given in the lab slide. Try to follow that example.arrow_forward
- (Pass or fail) Write a c++ program that prompts a student to enter a score.If the score is greater or equal to 60, display “you pass the exam”; otherwise, display “you don’t pass the exam”.Your program ends with input -1.Here is a sample run:Enter your score: 80You pass the exam.Enter your score: 59You don’t pass the exam.Enter your score: -1No numbers are entered except 0arrow_forward(Find the two lowest scores) Write a c++ program that prompts the user to enter the number of students and each student’s name and score, and finally displays the student with the lowest score and the student with the second-lowest score.arrow_forward(C++) Question: Write a function string middle(string str)that returns a string containing the middle character in str if the length of str is odd, or the two middle characters if the length is even. For example, middle("middle") returns "dd". I'm not getting the correct output. What am I doing incorrectly?arrow_forward
- (a) Write a C++ function that accepts a double typed number and return back the fractional part of the number. For example, if the number is 789.123, the number 0.123 should be returned.arrow_forward(JS)Write a function named "tweets" that takes a string as a parameter. If a message can hold at most 280 characters, calculate the smallest number of messages needed to hold all of the text in the input. The function should return the number it calculated.arrow_forward(C++) Write a program that captures input from the user and swaps the letters two at a time in the string. The first two characters change places, the third and fourth characters change places, etc. Assume that the program will only take an even number of characters, otherwise, there will be an error. For example: Home will output ohem, ocidgn will output codingarrow_forward
