in C++

Using your previous homework code:

1) Add a default constructor for the runners. ( one that has no parameters)

2) Add a constructor that takes a name and a bib number

3) Add a constructor that takes a name , a bib number and a sex.

Add setter functions that sets the time:

1) one that takes a string of the format : hh:mm:ss

2) one that takes an int that is the number of seconds the runner took to complete the race.

Please Note: You decide what format inside the class to store the time amount.  

Add getter functions that return the time:

1) one that returns a string in the format : hh:mm:ss

2) one that returns an int that this the time in seconds.

Add a comment section to your class and explain why you chose some things.

1) What data type did you decide on in the class for the time, why

2) What was an alternative? Is your decision a big decision or a small decision? why

Please note : Again pick one C++ data type inside the class to store the time.

Do not use two variables to store the time.

Please note: if you write conversion functions that if expected. Do not make them public.  

Please note: on the time returned as a string please test and verify that times like these contain the correct zeros not blanks. the format will always be either: ( b = blank, hh = hours, mm = minutes, ss = seconds )

bh:mm:ss

hh:mm:ss

so a time like 1:03:02 will NOT be displayed as : 1:3:2. I strongly suggest testing in these areas.

You may want to convert from a string to an integer for you students here is some

sample code

String conversion using stoi() or atoi()
stoi() : The stoi() function takes a string as an argument and returns its value. Following is a simple implementation:

filter_none

edit

play_arrow

brightness_4

Output:

stoi("45") is 45
stoi("3.14159") is 3
stoi("31337 geek") is 31337 



Please Note:  
You may decide that you need a function that returns a 2 character long string 
given an integer.   This is starter code .   
It does not fully help you in this project you will need to modify or add 
a bit of stuff to get it to be truly helpful. the statement 
temp+=number%10+48;
could be coded as :
temp+=number%10+'0';

Here is some starter code:

string convertInt(int number)
{
    if (number == 0)
        return "0";
    string temp="";
    string returnvalue="";
    while (number>0)
    {
        temp+=number%10+48;
        number/=10;
    }
    for (int i=0;i<temp.length();i++)
        returnvalue+=temp[temp.length()-i-1];
    return returnvalue;
}

this is my code from my previous homework:

#include<iostream>

#include<string>

using namespace std;

class Runner

{

private:

string bibnumber;

char gender;

int age;

string name;

string time;

public:

Runner()

{

bibnumber=" ";

gender=' ';

age=0;

name=" ";

time=" ";

}

int getAge()

{

return age;

}

string getName()

{

return name;

}

string getTime()

{

return time;

}

string getBin()

{

return bibnumber;

}

char getGender()

{

return gender;

}

void setCombinedGenderBib ( string bib)

{

gender=bib[0];

bibnumber=bib.substr(1,bib.length());

}

void setName(string name)

{

this->name=name;

}

void setTime(string time)

{

this->time= time;

}

void setAge(int age)

{

this->age= age;

}

};

int main()

{

Runner runner;

runner.setName("john");

runner.setAge(23);

runner.setTime("01:04:37");

runner.setCombinedGenderBib("M4321");

cout<<"Name : "<<runner.getName()<<endl;

cout<<"Bin Number : "<<runner.getBin()<<endl;

cout<<"Age : "<<runner.getAge()<<endl;

cout<<"Gender : "<<runner.getGender()<<endl;

cout<<"Time : "<<runner.getTime()<<endl;

return0;

Steam distillation. ANSWER IN DETAIL AND I WILL REWARD FIVE STARS TO FIRST PERSON TO ANSWER!!!!!!

A student steam distilled a mixtrue of toluene (bp 110.8 degrees Celsius) and water and noticed that distillate contained a larger volume of touleune than water. The student said to the professor, "I know there is something wrong with my experiment. I should have more water than toleune because water has a lowerboiling point. Should I redo the experiment?" The professor replied "do whatever you need to do" A classmate then said, "No, you dont need to redo it you DO have more water."

Explain in detail why the classmate is correct. Use calculations to support your explanation. Label all quantities used. Include all units.

Write a C++ function that receives an integer array along with its specified length. The function will replace only one of the smallest integers and one of the largest integers by 0. Then the function will return the average for the rest of the values in the array.

Test case array: 3, 8, 2, 6, 5, 3, 4, 7, 8, 2, 10, 7

Function should return: 5.3

Imagine that you are in the very first stages of
trying to figure out how to build a nuclear power reactor or a nuclear weapon
using fission. The first step you would consider is what kind of nuclei could
live for a reasonable length of time so that you could keep it around, but
would also be able to decay by some process that would give off lots of energy


1.Explore the conditions that produce a chain reaction (where a
substantial fraction of the nuclei fission) and those that do not. You want to
design a nuclear bomb. What are three design characteristics that are critical
to creating an effective bomb as oppose to a dud? Include the physics reasoning
behind why these are so important.

George has been selling 8,000 T-shirts per month for $9.50. When he increased the price to $10.50, he sold only 5,000 T-shirts.

Which of the following best approximates the price elasticity of demand?

-4.1538

-5.0769

-4.6154

-3.6923

Suppose George's marginal cost is $4 per shirt.

Before the price change, George's initial price markup over marginal cost was approximately ( 0.6368 OR 0.5211 OR 0.2895 OR 0.5789) . George's desired markup is   .

Since George's initial markup, or actual margin, was( LESS or GREATER) than his desired margin, raising the price was ( profitable or not profitable) .
