During the tax season, every Friday, the J&J accounting firm provides assistance to people who prepare their own tax returns. Their charges are as follows:

If a person has low income (<= 25,000) and the consulting time is less than or equal to 30 minutes, there are no charges; otherwise, the service charges are 40% of the regular hourly rate for the time over 30 minutes.
For others, if the consulting time is less than or equal to 20 minutes, there are no service charges; otherwise, service charges are 70% of the regular hourly rate for the time over 20 minutes. (For example, suppose that a person has low income and spent 1 hour and 15 minutes, and the hourly rate is $70.00. Then the billing amount is 70.00 X.40 X (45/60) = $21.00.)
Instructions
Write a program that prompts the user to enter yearly income, the hourly rate, the total consulting time. The program should output the billing amount. Your program must contain a function that takes as input the hourly rate, the total consulting time, and a value indicating whether the person has low income. The function should return the billing amount. Your program may prompt the user to enter the consulting time in minutes.

The cost to become a member of a fitness center is as follows:

the senior citizens discount is 30%;
if the membership is bought and paid for 12 or more months, the discount is 15%;
if more than five personal training sessions are bought and paid for, the discount on each session is 20%.
Write a menu-driven program that determines the cost of a new membership. Your program must contain a function that displays the general information about the fitness center and its charges, a function to get all the necessary information to determine the membership cost, and a function to determine the membership cost. Use appropriate parameters to pass information in and out of a function. (Do not use any global variables.)

An example of the program is shown below:

Welcome to Stay Healthy and Fit center.
This program determines the cost of a new membership.
If you are a senior citizen, then the discount is 30% of the regular membership price.
If you buy membership for twelve months and pay today, the discount is 15%.
If you buy and pay for 6 or more personal training session today, the discount on each session is 20%.
Enter the cost of a regular membership per month: 50

Enter the cost of one personal training session: 10

Are you a senior citizen (Y,y/N,n): n

Enter the number of personal training sessions bought: 3

Enter the number of month you are paying for: 1

The membership cost = $80.00
Since your program handles currency, make sure to use a data type that can store decimals with a decimal precision of 2.

1.

#include <iostream>
using namespace std;
void bill(float r, float t, bool i) {
if(i==1) {
if(t<=30)
cout<<"\nNO charges";
else
cout<<"\nCharges = $"<<0.4*r*(t/60);
}
else {
if(t<=20)
cout<<"\nNO charges";
else {
//if(t>60)
//t=t/60;
cout<<"\nCharges = $"<<0.7*r*(t/60);
}
}
}
int main()
{
float y_income,c_time;
bool income=0;
float rate;
cout<<"Enter Your yearly income:";
cin>>y_income;
cout<<"Enter the hourly rate:";
cin>>rate;
cout<<"Enter the total consulting time (in minutes)";
cin>>c_time;
if(y_income<=25000) {
income=1;
}
bill(rate,c_time,income);
return 0;
}

Output
