Thread: Help with Homework... Time is almost up.

What code have you written so far (and post it too)?

>> This is due to tommorow and I really want to be able to turn in my assignment so I don't get dropped (my teacher is very strict and also moving so fast that I am having trouble keeping up with this course).


Excuses, excuses. And what has prevented you from completing this assignment on your own? Sounds to me like you've set *yourself* up for failure...you deserve the grade!

Ok, I am going to be up all night working on this so I will just start with a easiest one. Tell if you think this looks ok?

Print 3 integers (from user input) in order from smallest to largest.

#include <iostream.h>

int main()

int a;
int b;
int c;
int first;
int second;
int third;

cout << "Enter 3 integers" << endl;
cin >> a >> b >> c;

if (a < b && a < c && b < c)

a = first;
b = second;
c = third;


if (b < a && b < c && a < c)

b = first;
a = second;
c = third;


if (c < a && c < b && b < a)

c = first;
b = second;
a = third;

if ( c < a && c < b && a < b)

c = first;
a = second;
b = third;


cout << first << " " << second << " " << third << endl;

return 0;


Now, with this part I seem to have the smallest number determined, but I am not sure how to implement this idea with a third number in the mix versus just comparing two integers.

You assign val1...3 the values of first...third but never define a value for first...third.

I think you wanted to assign val1..3 to first...third and not the other way around.

i.e.

Code:

first = val3;
second = val1;
third = val2;

On a sidenote, Sebastiani probably thought you were not going to post any of your own code. A lot of people come here, post their assignment and expect someone else to do it. We even had monetary offers... You can imagine that it ........es some people off.

Any idea? Yes.
you are approaching the problem wrong
You know how to do flowcharts? trace tables? all these should be done before you think of coding. would you build a house without a blueprint?
Design a high level chart, something that will just follow the flow of the program, dont worry about the hard parts of it, just cover flow. once you know the flow, you work on each function. Something to check if the input is within range. then a function for each of the different options. After that you just set up your switch.

Here i'll start you off a bit.
this is the function for option
A:
well at least the way i'd do it

Code:

#include <iostream>
using namespace std;


bool CheckSwitch(int a, int b)
{
	if ( a > b)
		return true;
	else
		return false;
}



void SmalltoLarge(int a, int b, int c)
{
	int temp;

	if (CheckSwitch(c,b))
	{
		temp = c;
		c = b;
		b = temp;
	

	}
	if (CheckSwitch(b,a))
	{
		temp = a;
		a = b;
		b = temp;

	}

	if (CheckSwitch(c,b))
	{
		temp = b;
		b = c;
		c = temp;
	
}

	cout<<a <<" " << b << " " << c <<endl;
}

int main()
{
	SmalltoLarge(3,3,1);
	int x;
	cin>>x;
}

Code:

(a) 

#include<iostream>
using namespace std;

void Assend();
int input[2];
int i1,i2,i3;

void Assend(){
	
	input[0]=i1;
	input[1]=i2;
	input[2]=i3;
	int size = 3, temp;
	// Bubble sort
	for(int x=0; x<(size-1); x++)
	for(int y=1; y<(size-x); y++){
		if ( input[y-1] > input[y] ){
		temp = input[y-1];
		input[y-1]=input[y];
		input[y] = temp;
			}
		}
	cout<<input[0]<< ", " << input[1] << ", " << input[2] << ", " << endl;
	}

void main()
	{
	char c;
	cout<< "Enter a character a-f: " ;
	cin>> c;
	bool valied = (int)c>102;
	if(valied)
		cout<<"Charactor out of range"<<endl;
	
	cout<< "Enter an integer: "<<endl;
	cin>>i1;	
	cout<< "Enter a 2nd integer: "<<endl;
	cin>>i2;	
	cout<< "Enter a 3rd integer: "<<endl;
	cin>>i3;
	
	switch(c)
	{
		case 'a':
		Assend();
	}
	}

I dont' do flowcharts or trace tables or anything like that before programming... only for really big projects... and don't mix programming and building a house... that is one of the worst analogies i've ever heard... you have so much more room to move when writing a program than when you do building a house...

kasun: did you even read the assignment? check his restrictions...

maybe so, but you should never tell anybody to do what their assignment explicity tells them not to do... that's how you fail your courses and get nowhere in programming... sometimes programmers have to write what the client wants them to write... not what they want to write...
