Distance File Modify the Distance Calculator program that you wrote for Programming Problem 1 so it writes its output to a file instead of displaying it in a ListBox control. Open the file in Notepad or Visual Studio to confirm the output.
testScore Array:
Student1 = 75Student2 = 24Student3 = 73Student4 = 65Student5 = 86Student6 = 45Student7 = 56Student8 = 94
Write code in C# to process the student's result from the array(testScore) based on the condition below and display all the score that are below the passing marks onto a ListBox (lstFailList).
Condition: The student is passed if the grade is more than 50.
The strItems array is declared as follows: Dim strItems(20) As String. The intSub variable keeps track of the array subscripts and is initialized to 0. Which of the following Do clauses will process the loop instructions for each element in the array? a. Do While intSub > 20 b. Do While intSub < 20 c. Do While intSub >= 20 d. Do While intSub <= 20

When the program runs, it should ask the user to enter data for each month. (The average temperature should be calculated.) Once the data are entered for all the months, the program should calculate and display the average monthly rainfall, the total rainfall for the year, the highest and lowest temperatures for the year (and the months they occurred in), and the average of all the monthly average temperatures.

- Geometric Progression Printer As you might recall, a Geometric Progression (or GP) is a sequence of elements in which the next number in the sequence is obtained by multiplying the previous number by the common ratio. The next number in the sequence is obtained by using this formula: a_na_1* r(n-1) While the sum of all numbers in the sequence is obtained using any of these formulae: If r 1, sum = a* n If r != 1 and r> 1, sum= a[(r¹-1)/(r - 1)] If r != 1 and r < 1, sum = a[(1 - r¹)/(1-r)] where a n = next number in the sequence, a_1 = first number in the sequence, r = common ratio, n = number of terms Your task is to write a Python program that 1. Accepts the necessary inputs from the user, i.e., start value (a_1), common ratio (r), and number of generate to generate (n). 2. Generates the Geometric Progression (GP) sequence starting from a_1 to n. 3. Prints out the GP HORIZONTALLY not VERTICALLY, e.g. 3, 9, 27, 81, 243, 729 .... 4.
