PLEASE WRITE CODE FOR C++ !

Time Validation, Leap Year and Money Growth

PartA: Validate Day and Time

Write a program that reads a values for hour and minute from the input test file timeData.txt . The data read for valid hour and valid minute entries. Assume you are working with a 24 hour time format. Your program should use functions called validateHour and validateMinutes. Below is a sample of the format to use for your output file  timeValidation.txt :

   Line 1 13:45 hours and minutes are valid

   Line 2 25:30 hour is invalid minutes are valid

   Line 3 11:33 hour is valid and minutes are valid

   Line 4 26:61 hour and minutes are both invalid

Use the file timeData.txt as input data to you program

Upload your C++ file as timeValidation.cpp

Upload your output file as timeValidation.txt

PartB: Leap Years

Write a program which will calculate the number of leap years between any two years from 1900 to 2099. Program should prompt for starting year and ending year. The program should validate that the starting date and ending dates are within the above range. The program should also validate that the ending year is greater than the beginning year. The program should have Boolean function that tests if a given year is a leap year. Use a for loop to call the leap year test function.

The leap year algorithm:

if (year is not divisible by 4) then (it is not a leap year)
else
if (year is not divisible by 100) then (it is a leap year)
else
if (year is not divisible by 400) then (it is not a leap year)
else (it is a leap year)

(see http://en.wikipedia.org/wiki/Leap_year (Links to an external site.)Links to an external site. )

Your program should access the input file dataForLeapTests.txt to test your program. This file contains pair of years separated by a space. The first year is the beginning year. The second year is the ending year.

Example of output format your program should create:

2000-2016 there are 5 leap years in this range

2015-2020 there are 2 leap years in this range

1859-1910 (invalid range error for calculation)

Submit the following files to Canvas: leapYear.cpp and leapYearRun.jpg

PartC: How much to save

You have several dates you plan to go on a trips. Calculate how many days it will take you to raise your goal for money for a given trip if you start with an initial deposit amount of 2 cents. Each day you will double the amount of money to add to your trip fund. Day one would be 2 cents, day two add 4 cents, day three add 8 cents and so on. Note 2 cents = .02 dollars.

Calculate the amount of days it will take to earn your target trip money for each trip using the input text file moneyNeededForMyTrips.txt

Save your results in the file daysNeededPerTrip.txt

Use the file tripsToTake.txt as input to your program. Output the trip name, amount and number of days it will take.

Example input data:

Hawaii 4000

Brazil 7000

Take your input data from the file tripSavingPlans.txt

Answer 1

Part a)

here is your program:

#include<iostream>
#include<fstream>
using namespace std;
bool validateHour(int h) //function which will check validity of hour
{
if(h<0 || h>23)
{
return false;
}
return true;
}
bool validateMinutes(int m) //function which will check validity of minutes
{
if(m<0 || m>59)
return false;
return true;
}

int main()
{
ifstream f;
f.open("timeData.txt"); //here the file will be opened
  
ofstream of;
of.open("timeValidation.txt"); //in this file we will write data
string s;
int i=1;
while(f)
{
f>>s;
int h=(s[0]-'0')*10+(s[1]-'0'); //convert character to integer
int m=(s[3]-'0')*10+(s[4]-'0');
bool a=validateHour(h);
bool b=validateMinutes(m);
if(!f)
break;
of<<"Line "<<i<<" "<<h<<":"<<m<<" ";

if(a)
{
if(b)
{
of<<"hour is valid and minutes are valid\n";
}
else
{
of<<"hour is valid and minutes are valid\n";
}
}
else{
if(b)
of<<"hour is invalid minutes are valid\n";
else
of<<"hour and minutes are both invalid\n";
}
i++;

}
}

here is the ss of both input and output file:

part B)

here is the program for this part

#include<iostream>
#include<fstream>
using namespace std;

bool leap_year(int y) //this function will check for leap year
{
if(y%4!=0)
return false;
else if(y%100!=0)
return true;
else if(y%400!=0)
return false;
else
return true;
}
int main()
{
ifstream f;
f.open("dataForLeapTests.txt"); //here the file will be opened
  
ofstream of;
of.open("leapYearRun.txt"); //in this file we will write data
int y1,y2;
while(f)
{
f>>y1>>y2;
if(!f)
break;
of<<y1<<"-"<<y2;
if(y1<1900 || y2>2099 || y1>y2)
of<<" (invalid range error for calculation)\n";
else
{
int i=0;
for(int y=y1;y<=y2;y++)
{
if(leap_year(y))
i++;
}
of<<" there are "<<i<<" leap years in this range\n";
}
}
  
}

Part c)

here is the required program

#include<iostream>
#include<fstream>
using namespace std;

int daysNeeded(int money) //this will calculate days
{
money=money*100; //convert dollar into cents
int d=1;
int it=2;
while(it<money)
{
d++;
it*=2;

}
return d;
}
int main()
{
ifstream f;
f.open("moneyNeededForMyTrips.txt"); //read from this file
ofstream of;
of.open("daysNeededPerTrip.txt"); //put output in this file
string s;
int money;

while(f)
{
f>>s>>money;
if(!f)
break;
of<<s<<" "<<daysNeeded(money)<<"\n";
}
}
