The algorithm below is used to simulate the results of flipping a coin 4 times. Consider the goal of determining whether the simulation resulted in an equal number of heads and tails.
Step 1: Initialize the variables heads_counter and flip_counter to 0.
Step 2: A variable coin_flip is randomly assigned a value of either 0 or 1. If coin_flip has the value 0, the coin flip result is heads, so heads_counter is incremented by 1.
Step 3: Increment the value of flip_counter by 1.
Step 4: Repeat steps 2 and 3 until flip_counter equals 4.
Following the execution of the algorithm, which of the following expressions indicates that the simulation resulted in an equal number of heads and tails?
A. coin_flip = 1
B. flip_counter = 1
C. flip_counter = 2
D. heads_counter = 2

(programming exercise 3-10). a retail company must file a monthly sales tax report listing the total sales for the month, and the amount of state and county sales tax collected. the state sales tax rate is 4 percent and the county sales tax rate is 2 percent. design a modular program that asks the user to enter the total sales for the month. from this figure, the application should calculate and display the following: - the amount of county sales tax - the amount of states sales tax - the total sales tax (county plus state) some of the code has already been provided below. complete the missing code below. // global constants for tax calculations constant real county_tax_rate = .02 constant real state_tax_rate = .04 // main module module main() // local variables declare real monthsales, countytax, statetax // get month sales display “enter monthly sales: ” input monthsales // write the statement to calculate county tax // write the statement to calculate state tax // display tax amount call showtaxes(monthsales, countytax, statetax) end module // the showtaxes module accepts monthsales, countytax, statetax // as arguments and displays the resulting data // write the showtaxes module
