COUNT LETTER CASE PROGRAM Create a new project and name it YourName_CountLetterCase (example: Alyaa_CountLetterCase) and start your program with your (Name, ID, GROUP) as a comment. Question: Write a Java program that reads one line of String from the user then counts the occurrences of upper-case letters and lower -case letters in that string. Tip:Use while/for loop to search and count the occurrences of upper-case letters and lower-case letters in the string. EXAMPLES OF THE OUTPUT: E Output - CountLetterCase (run) x run: Enter a line of string: Welcome to Java Programming Language! Found 4 upper-case letters in the string
• Use a while loop • Use multiple loop controlling conditions • Use a boolean method • Use the increment operator • Extra credit: Reuse earlier code and call two methods from main Details: This assignment will be completed using the Eclipse IDE. Cut and paste your code from Eclipse into the Assignment text window. This is another password program. In this case, your code is simply going to ask for a username and password, and then check the input against four users. The program will give the user three tries to input the correct username-password combination. There will be four acceptable user-password combinations: • alpha-alpha1 • beta-beta1 • gamma-gamma1 • delta - delta1 If the user types in one of the correct username-password combinations, then the program will output: "Login successful." Here are a couple of example runs (but your code needs to work for all four user-password combinations): Username: beta Type your current password: beta1 Login successful. Username: delta Type…
1. In the first loop, the low number will be the starting point for the loop and thehigh will be the ending point. The loop should display the iterator number andthat number x 10 on the same line, separated by a tab. See example on p. 177.2. The second loop should accumulate all the numbers between the starting pointand ending point. You will need to create and initialize an accumulator such astotal before you start the loop.
Programming Language: C++ Develop a Tic Tac Toe game that will match a player against the computer. Do’s: Use a typical 3 x 3 board. The horizontal axis should be labeled A, B, C. The vertical axis should be labeled 1, 2, 3. For Example: the attatched picture. Use User-Defined Functions. Use Branching. Use Loops. Use String functions. Randomly determine who will move first, the human or computer. Assign O to the computer and X to the Human player. Ask the user to select their move using the horizontal and vertical position. For example: A1 for the upper left square, or B2 for the center square. After each move, redraw the board with the X’s and O’s in the right positions. After each game, ask the user if they want to play again. If they do, start the game again. Do not’s: Don’t use User Classes or Objects Don’t use images

O while loop checks the condition before the loop begins, whereas the do-while loop executes the body at least once before checking the condition. O while loop is used for counter-controlled and do-while, is used for a sentinel loop. O while loop is used for selection controlled and do-while is used for an infinite loop. O while loop is used for endless controlled control and do-while, is used for counter-controlled loop. Save All Ans Click Save and Submit to save and submit.

Question#2. The distance a vehicle travels can be calculated as fallout: Distance = Speed * Time For example, if a train travels 60 miles-per-hour for three hours, the distance [raveled is 120 miles. Write a program that asks for the speed of a vehicle (in miles-per-hour) and the number of hours it has traveled. It should use a loop to display the distance a vehicle has traveled for each hour of a time period specified by the user. For example, if a vehicle is traveling at 40 mph far a three-hour time period, it should display a report similar to the one chat follows: Hour Distance Traveled 1 90 2 100 3 150 Input Validation: Do not accept a negative number for speed and do not accept any value les than 1 for time traveled.
CENGAGE MINDTAP 4-Accumulating Totals in a Loop in Java Accumulating Totals in a Loop f Ⓡ Summary In this lab, you add a loop and the statements that make up the loop body to a Java program that is provided. When completed, the program should calculate two totals: the number of left-handed people and the number of right-handed people in your class. Your loop should execute until the user enters the character X instead of L for left-handed or R for right-handed. The inputs for this program are as follows: R, R, R, L.L.L. R. L, R, R, L, X Variables have been declared for you, and the input and output statements have been written. Instructions 1. Ensure the file named LeftOrRight.java is open. 2. Write a loop and a loop body that allows you to calculate a total of left-handed and right-handed people in your class. 3. Execute the program by clicking Run and using the data listed above and verify that the output is correct. Grading When you have completed your program, click the Submit…
"Simon Says" is a memory game where "Simon" outputs a sequence of 10 characters (R, G, B, Y) and the user must repeat the sequence. Create a for loop that compares the two strings starting from index 0. For each match, add one point to userScore. Upon a mismatch, exit the loop using a break statement. Assume simonPattern and userPattern are always the same length. Ex: The following patterns yield a userScore of 4:simonPattern: RRGBRYYBGY userPattern: RRGBBRYBGY #include <iostream>#include <string>using namespace std; int main() { string simonPattern; string userPattern; int userScore; int i; userScore = 0; cin >> simonPattern; cin >> userPattern; /* Your solution goes here */ cout << "userScore: " << userScore << endl; return 0;}
