(Variable-Length Argument List: Calculating Products) Write a program that calculates theproduct of a series of integers that are passed to function product using a variable-length argumentlist. Test your function with several calls, each with a different number of arguments.

(IN C LANGUAGE) Binary-Decimal / Decimal Binary . Between 0 and 255 a number will be decided randomly by computer. Then asks to user 3 times a random digit of binary value of the that number. If user enters wrong number for a digit program will select another random number and ask random times random digit. For example: Computer selected number as 163 ( Which is 10100011) What is the digit 2 (question 1/3) :User enter 1 CorrectWhat is the digit 4 (question 2/3) : User enter 0 CorrectWhat is the digit 7 (question 3/3) : User enter 0 CorrectUser finished the quest with 3 input .

(Geometry: area of a regular polygon) A regular polygon is an n-sided polygon in which all sides are of the same length and all angles have the same degree (i.e., the polygon is both equilateral and equiangular). The formula for computing the area of a regular polygon is n x s? Area 4 X tan Here, s is the length of a side. Write a program that prompts the user to enter the number of sides and their length of a regular polygon and displays its area. Here is a sample run:

(Integers Added Together) Create a program that employs the for statement to sum a succession of integers in a single line. Assume that the first integer read defines the number of values that must be entered before the next one may be read. Your software should only read one value per input statement in order to avoid memory leaks. A typical input sequence may be 5 100 200 300 400 500 (or something like). where the number 5 signifies that the items after it are to be added together.

(Algebra: solve 2 x 2 linear equations) You can use Cramer's rule to solve the following 2 x 2 system of linear equation: ax + by = e ed – bf af- ec ad - bc cx + dy = f ad – bc y = Write a program that prompts the user to enter a and f and display the result. If ad - bc is 0 b, c, d , e, , report that The equation has no solution.

(Sort three integers) Write a program that prompts the user to enter THREE integers and display the integers in decreasing order. Prepare your problem analysis and algorithm (pseudocode or flowchart) to plan your solution.

(Java) The greatest common divisor of two positive whole numbers and n1 and n2 is the largest number g such that g evenly divided into both n1 and n2. Write a complete program that takes two positive whole numbers from the user and displays the common divisor.

(Rounding Numbers) Function floor may be used to round a number to a specific decimalplace. The statementy = floor(x * 10 + .5) / 10;rounds x to the tenths position (the first position to the right of the decimal point). The statementy = floor(x * 100 + .5) / 100;rounds x to the hundredths position (the second position to the right of the decimal point). Writea program that defines four functions to round a number x in various waysa) roundToInteger(number)b) roundToTenths(number)c) roundToHundreths(number)d) roundToThousandths(number)For each value read, your program should print the original value, the number rounded to thenearest integer, the number rounded to the nearest tenth, the number rounded to the nearest hundredth, and the number rounded to the nearest thousandth.

(In java) Lab6C: Cha-Ching For this lab, use a do-while loop.A sentinel loop is a loop (a special while loop or a do-while loop) that continues to process data until itreaches a specific value(s) that signals that it should stop looping; this special value(s) is usuallyindicated as the condition of the while or do-while loop. A good example of a sentinel loop is the whileloop that you had to write to verify user input in Lab6B, the special values were anything in the range of1 to 1000. Another very common application for this is allowing a user to rerun a program.Please write a very simple program that mimics a bank account. The program should start the user outwith $1000. The program should print out a welcome menu once with the options present for the user.The program should allow the user to make a deposit, withdrawal, and see their current balance.Every time the user deposits or withdraws, the program should show the user their new balance; itshould also ask the user if they want…
