Guessing game: Read a number until it's equal to a chosen number (first it can be a hard-coded constant or #define, or you can check rand() later). In case of wrong guessing help the user by printing whether the guessed number is to small or too big. ( in C language)

Lab 5 Problem Statement
Write a program that quizzes the user on the names of the capital cities for all the states in the United States. Each state is presented to the user, and they must enter the name of the capital. The program then either tells the user they're correct or tells them the correct answer. The user's answer should not be case-sensitive. At the end, the program tells the user the total number they got correct. Here's an example:
What is the capital of Alabama? MontogomeryThe correct answer is Montgomery.What is the capital of Alaska? juneauThat is the correct answer!...You got 32 out of 50 correct!
The state capitals will be stored in a 2D String array of size 2 x 50, with the first column the name of the state and the second the name of the capital city, for all 50 states. To create the state capitals array, follow these instructions:
Copy the String from the attached file into your program (found below these instructions). The String is a pipe delimited…
JAVA Programming Problem 2 - Diving
In the sport of diving, seven judges award a score between 0 and 10, where each score may be a floating-point value. The highest and lowest scores are thrown out and the remaining scores are added together. The sum is then multiplied by the degree of difficulty for that dive. The degree of difficulty ranges from 1.2 to 3.8 points. The total is then multiplied by 0.6 to determine the diver’s score. Write a computer program that will ultimately determine the diver’s score. This program must include the following methods:
A method name inputValidScore that inputs one valid score for one judge for one diver. This method will return the valid score.
A method named inputAllScores that creates an array to store the scores for all judges for the diver. This method will fill the array with a valid score from each judge. This method does not take input arguments, but it does return the array of scores.
A method named inputValidDegreeOfDifficulty that inputs a…

- Java question Write a program that plays the Rock-Paper-Scissors game againstthe computer. When played between two people, each personpicks one of three options (usually shown by a hand gesture) atthe same time, and a winner is determined. In the game, Rockbeats Scissors, Scissors beats Paper, and Paper beats Rock. The program should randomly choose one of the three options (with-out revealing it), then prompt for the user's selection. At that point, the program reveals both choices and prints a statementindicating if the user won, the computer won, or if it was a tie.Continue playing until the user chooses to stop, then print thenumber of user wins, losses, and ties.arrow_forwardComputer Fundamentals and Programming 2 Write a program that determines a student’s grade.

- CPSC 130: Introduction to Computer Programming I Program 3: Decisions In this programming assignment, you will implement two Java programs that deal with decisions. Part1: Determine correct quadrant for angle Complete the program below so that it prompts the user for an angle in degrees, and prints out the quadrant in which the angle is located, represented by Roman numerals, as shown in the following figure. 180⁰ II E III 90⁰ 270⁰ IV Notice that the value of the angle starts at zero degrees at the rightmost point of the circle, moving counterclockwise around the circle as the number of degrees grows. For instance, if the input angle has 100 degrees, it is in quadrant II, while an angle of 300 degrees is in quadrant IV and an angle of 45 degrees is in quadrant I. Each quadrant contains 90 degrees and starts at a multiple of 90. For example, 89 degrees is in quadrant I and 90 degrees is in quadrant II. All the input angle values must be integers between 0 and 359. If the value of an…arrow_forward5. You are playing a game that has two dice - one die has 6 sides numbered 1 through 6 and the second die has 8 sides numbered 1 through 8. A turn involves rolling both die together. Write Java code to play 1,000 turns and keep track of the sum of the two dice in each roll I.e, (2 through 14). When all 1,000 turns have been completed, print a formatted table showing the value of the sum of the two dice (2 through 14) and the number of times that value occurred.arrow_forwardThe value of x at the end.int x = 1;x = x + 1;x++;arrow_forward

Each exam score will be an integer in the range 0 to 100. Input will end when the user enters -1 as the input value. After all scores have been read, display the number of students who took the exam, the minimum score, the maximum score, the average score, and the number of As where an A is a score in the range 90-100. Make sure your average a decimal point. Only count A’s, not other grades. Note that you do not need to do any error checking on the input for this problem. This should be done as a standard sentinel-controlled while loop.arrow_forward
