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.]
(Comparing Integers) Write a program that prompts the user to enter the edges of a triangle and compares them. If all edges are equal, display Equilateral Triangle; if only two edges are equal, display Isosceles Triangle and if none of the edges are equal, display Scalene Triangle. Use c++ program.
(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.

- (Count the number of Vowels and Consonants) Write a program that reads an unspecified number of uppercase or lowercase alphabets, and determines how many of them are vowels and how many are consonants. Enter zero to signify the end of the input.(sentinel values is 0 to stop or exit the program).Use c++ program.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_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
- (Sum the digits in an integer) Programming Exercise 2.6 prompts the user to enter an integer between 0 and 1000, and displays the sum of all digits in the integer. Write a program that prompts the user to enter a three-digit integer. The program displays the sum of all digits in the integer if the input is valid; otherwise, it displays a message indicating that the integer is not a three-digit number and hence, is invalid. Use C++ program.arrow_forward(Count positive and negative numbers and compute the average of numbers) Write a c++ program that reads an unspecified number of integers, determines how many positive and negative values have been read, and computes the total and average of the input values (not counting zeros). Your program ends with the input 0. Display the average as a floating-point number. Here is a sample run:Enter an integer, the input ends if it is 0: 1 2 -1 3 0The number of positives is 3The number of negatives is 1The total is 5.0The average is 1.25arrow_forward(Bar-Chart Printing Program) One interesting application of computers is drawing graphsand bar charts. Write a program that reads five numbers (each between 1 and 30). For each numberread, your program should print a line containing that number of adjacent asterisks. For example,if your program reads the number seven, it should print *******.arrow_forward
- (True or False) If ? is the length of str, then str.Substring(n − 2) is the string consisting of the last two characters of str.arrow_forward(Diameter, Circumference and Area of a Circle) Write a program that reads in the radiusof a circle and prints the circle’s diameter, circumference and area. Use the constant value 3.14159for π. Perform each of these calculations inside the printf statement(s) and use the conversion specifier %f. [Note: In this chapter, we’ve discussed only integer constants and variables. In Chapter 3we’ll discuss floating-point numbers, i.e., values that can have decimal points.]arrow_forwardQ) Write a program in C++ language that enter an integer number from keyboard then check the number if it is negative, positive, or zero then print the result of checking in the screen of the computer.. (Note: using (if-statement)arrow_forward
- Q1: (Palindrome number) Write a program of C++ that prompts the user to enter a three-digit integer and determines whether it is a palindrome number. A number is palindrome if it reads the same from right to left and from left to right. Here is a sample run of this program: Enter a three-digit integer: 121 121 is a palindrome Enter a three-digit integer: 123 123 not a palindromearrow_forward(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.arrow_forward(Guess the Number Modification) Modify the program of Exercise 5.32 to count the number of guesses the player makes. If the number is 10 or fewer, print Either you know the secret oryou got lucky! If the player guesses the number in 10 tries, then print Ahah! You know the secret!If the player makes more than 10 guesses, then print You should be able to do better! Why shouldit take no more than 10 guesses? Well, with each “good guess” the player should be able to eliminatehalf of the numbers. Now show why any number 1 to 1000 can be guessed in 10 or fewer tries.arrow_forward
