I need to write a program that prints out all the odd or even integers between any two integers (inclusive) entered by the user. The user should be able to select whether odd or even integers are to be printed. Use a while loop to force correct entry for the odd/even choice (use type char for choice).

The program should contain two ways for printing integers, and automatically produce two outputs (which obviously must be identical); these two ways are in seperate functions.

a. The first way your code should contain the odd/even conditional statements before a while loop, and use a loop increment of two.

b. In the second way the odd/even conditional statement(s) should be inside the while loop, which should use a loop increment of one.

Okay.. we got the problem but how far have you gone..
Have you started making this?

Post your code if you need some clarification..

Oops yeah I have written some code! Having trouble with my computer at the moment, working on it...

I can't find the file I wrote anymore!

I have:

//Programmer: Charles Syms

//Folder: H:\My Documents\Programming Assignments\Assignment 3
//Description: Question 9 of Assignment 3

#include <iostream>
#include <conio.h>
using namespace std;

void printInteger( char );
//-----------------------------------------------------------------------------
int main(int argc, char *argv[])
{   
   int myInteger1;
   int myInteger2;
   
   cout << "Enter any 2 integers: " << endl << endl;
   cin >> myInteger1;
   
   cout << "... and the next one: " << endl << endl;
   cin >> myInteger2;
    
   _getch();
   return 0;
}

even if you could help me towards what I need to do...

[CreamDelight]

okay here's what you need..

you said that the user will select if the one to be printed is odd or even, so you need to let the user input..

Next.. finish your function..

void printInteger( char )

i'll ask you, in your college algebra, how do you identify if a number is odd or even?
If you will get that you will easily get the code..

I never did algebra at college...! I know that it has to be divisible by 2. so 2n even 2n+1 odd

Your right..

so...

 if(n % 2 == 0)
      i am an even
 else
      i am an odd

...You already got the idea

this snippet will print all even integers in a range of 0 - 10..

for(int x = 0; x <= 10; x++)
{
   if(x % 2 == 0)
      printf("%d\n", x);
}

yes - but the user should get to decide whether odd or even integers are to be printed? and also a while loop needs to be used, not a for loop.

you need to scan an input..

scanf("%c", choice);

for(int x = 0; x <= 10; x++)
{
     if(choice == 'o')
     {
       if(x % 2 != 0)
           printf("%d\n", x);
     }
     else if(choice == 'e')
     {
       if(x % 2 == 0)
          printf("%d\n", x);
     }
}

oH.. i'm giving the whole code..
i think you can see everything here so any problem just refer to the code and your logic..

can you not give me the rest?
I'm confused now

[CreamDelight]

I think its illegal here to let other people do the code and your not giving your part..
maybe do some and code and post here were your stuck..

I have this:

//-----------------------------------------------------------------------------

#include <iostream>
#include <conio.h>
using namespace std;

void printInt1( char number );
void printInt2( char  );
//-----------------------------------------------------------------------------
int main(int argc, char *argv[])
{   
   int myInteger1;
   int myInteger2;
   
   cout << "Enter any 2 integers: " << endl << endl;
   cin >> myInteger1;
   
   cout << endl << "... and the next one: " << endl << endl;
   cin >> myInteger2;
   
   printInt1( myInteger1 );
    
   _getch();
   return 0;
}
//-----------------------------------------------------------------------------
void printInt1( char number );
{
   scanf("%c", choice);

   for(int x = 0; x <= 10; x++)
   {
      if(choice == 'o')
      {
      if(x % 2 != 0)
      cout << ("%d\n", x);
      }
      
      else if(choice == 'e')
      {
      if(x % 2 == 0)
      cout << ("%d\n", x);
      }
   }
}

Your function should receive three parameters..
Like this..

void printInt1( char choice, int int1, int int2 )

char choice is for the decision of the user if he will display it odd or even..
int1 is for the first integer and int2 for the second..

having these three parameters we can now start the loop..

void printInt1( char choice, int int1, int int2 )
{
   for(; int1 <= int2; int1++)
   {
      if(choice == 'o' || choice == 'O')
      {
      if(int1 % 2 != 0)
      cout << int1 << endl;
      }
      
      else if(choice == 'e' || choice == 'E')
      {
      if(int1 % 2 == 0)
      cout << int1 << endl;
      }
   }
}

That's all i can offer to you..
You should be the one who will make your main function...

thankyou

I'm still amazingly confused, any help you could offer me would be much appreciated. Understandable if you can't... I have this:

{   
   int myInteger1;
   int myInteger2;
   
   cout << "Enter any 2 integers: " << endl << endl;
   cin >> myInteger1;
   
   cout << endl << "... and the next one: " << endl << endl;
   cin >> myInteger2;
   
   printInt1;
    
   _getch();
   return 0;
}
//-----------------------------------------------------------------------------
void printInt1( char choice, int int1, int int2 )
{
   for(; int1 <= int2; int1++)
   {
      if(choice == 'o' || choice == 'O')
      {
      if(int1 % 2 != 0)
      cout << int1 << endl;
      }
       
      else if(choice == 'e' || choice == 'E')
      {
      if(int1 % 2 == 0)
      cout << int1 << endl;
      }
   }
}

I don't know what to do next.
