Write a program that asks the user to enter the size of a triangle(an integer from 1 50). Display the triangle by writing lines of asterisks. The first line will have one terisk, the next two and so on, with each line having one more asterisk than the evious line, up to the number entered by the user. On the next line write one fewer terisk and continue by decreasing the number of asterisks by one for each ccessive line until only on asterisk is displayed. (Hint: Use nested for loops; the utside loop controls the number of lines to write, and the inside loop controls the

Q6:) Write a code program to draw the figure as shown below. Start from point A( 40, 60 ). Use form scale (0, 280)-(320, 0) A 70 Your answer 100 70 0120 50 60 50
Exercise II Write a program that finds the positive integer solutions of the following equation ax³ + bx² + cx' + d = 0. The user enters the values of coefficients a, b, c and d. The program should test each integer starting from -50 to 50, and each time the equation is equal to zero, it prints its value as well as "is a solution". At the end, it displays the total number of positive integers found. Note that if the equation has more than one solution, the plural word “solutions" is used in the output. Sample run 1: Enter the coefficient of a, b, c, d: 1 -8.5 21 -13.5 1 is a solution 3 is a solution The equation has 2 integers as solutions Sample run 2: Enter the coefficient of a, b, c, d: 6 48 103.5 67.5 The equation has no integer solutions Sample run 3: Enter the coefficient of a, b, c, d: 1 -1 -12 0 4 is a solution The equation has 1 integer solution
1# Write a program that allows users to choose from one of three shapes: Squares, Circles or (right) Triangles. Allow the user to use the first letter of the shape (S, C, T) to specify what they want. After the shape is selected, ask the user for the appropriate data to calculate the shape's area, and then and print that area value to the screen for them. Area formulas you can use: Triangle: % base x height Square: length x length Circle: % Pl x radius? Notes: The floating-point data type will be your friend here. Round your area answer so that no more than 2 decimal places are shown when printing on the screen. You can use 3.1415 for Pl; Think about this as a CONSTANT in your code. For this part and especially part (b) below, think about componentizing your code. So one gigantic main() is not a best practice and not what we want to see here. Remember what we discussed about "procedural decomposition" and functions last week!
1. Write a program that lets the user guess whether a randomly generated integer would be even or odd. The program randomly generates an integer and divides it by 2. The integer is even if the remainder is 0, otherwise odd. The program prompts the user to enter a guess and reports whether the guess is correct or incorrect.
Body mass index (BMI) is a measure of health based on weight. It can be calculated by taking your weight in kilograms and dividing it by the square of your height in meters. Write a program that prompts the user to enter a weight in pounds and height in inches and displays the BMI. Note that one pound is 0.45359237 kilograms and one inch is 0.0254 meters.
Task 1: Find the even multiples of any number chosen by the user in a given range - the user should specify the multiples of which number they want to print and a minimum and maximum value. The multiples printed should be within the [minimum, maximum] range. For example, if the user chooses the number 7 and would like to print all even multiples in the [15, 60] range, the program should print all the even multiples that are bigger than or equal to 15 (minimum), but smaller than or equal to 60 (maximum). The program should keep a count of how many numbers were printed and should output that count, as well as the numbers. The output then, for the example given, should be 28, 42, 56, and the count should be 3. Shell scripting
Enter three values of angles and then print "Triangle" or "Not a triangle" depending on whether these three angles can form a triangle or not. In addition, if it is a right angle triangle then print "Right-Angle Triangle" or "Non Right-Angle Triangle".
Write a program that lets the user enter the loan amount and loan period in number of years and displays the monthly and total payments for each interest rate starting from 5% to 8%, with an increment of 1/8.
Task 3: Find the numbers that can be expressed as the product of two nonnegative integers in succession and print them in increasing order. For each number found the program should check whether the number is a multiple of 5 and indicate this in the output. (For example, 30 is such a number as it can be written as the product of 5 and 6 (30=5x6), which are two numbers in succession.) The user should specify how many such numbers they want to print. Your application should be user friendly. First, you create an initial menu that the user sees when they execute the application. The menu should display the list of operations (the three tasks) that the application can perform. In your menu design, if user enters M or m, the application should print a list of the multiples of the number The user specifies how many numbers to print. The program should display the user’s selection before printing the output. If the user enters a selection which is different from the choices offered, the…
4. Area of a Rectangle • Write a program that compares the area of two rectangles. You can do this several ways. one way is to add the length and width of each rectangle to get it's area and then compare the two areas together. • The program should ask for the length and width of two rectangles and then tell the user which rectangle has the greater area, or if the areas are the same. • The area of a rectangle is the rectangle's length times its width. Name the source code file yourName HW4.py. • Test and run the program. Capture the output console and save it as an image file named yourName HW4 output.jpg. • Submit the py and the image files through Canvas.

The date June 10, 1960, is special because when we write it in the following format, the month times the day equals the year: 6/10/60 Write a program that ask the user to enter a month in numeric format, a day and a two-digit year. The program should then determine whether the month times the day is equal to the year. If so, it should display a message saying the date is Magic. Otherwise, it should display a message saying the date is not Magic. Output should look as shown below. Create test data and place in a file. Name the code file Last Name + First Initial + "-MagicDates.s", for example "SmithJ- MagicDates.s". Name the test data file in a similar manner. Upload the program and test data files to the Dropbox. 6/10/60 is Magic! 6/10/70 is not Magic. 2/11/22 is Magic!
C Programming Language Task: Pascal's Triangle Write a program to print Pascal's triangle. In Pascal's triangle Each number is the sum of the two numbers above it.
