    well here is what i did .. some of it ..

    int main()
    {

    int n;

    cout<<"ENTER N:";
    cin>>n ;

    cout<<"\t" << n/2<<"="<<"\t"<<n/2<<"\t";

    I don't quite see what you're doing. Yes your program will have to change for 5 because 5 / 2 = 2.5 . This is a floating point number and cannot be represented using an integer accurately. Change your data types to floats and try it out.

    5/2 =2.5
    2.5=2.5

    what do you mean will it change when the input is 5? why don't you try it?
    plus it should be obvious that n/2=n/2, it's mathmatical law.

    #include <iostream.h>
    #include <stdlib.h>

    int main()
    {

    float n;


    cout<<"ENTER N:";
    cin>>n ;

    cout<<"\t" <<n/2<<"="<<"\t"<<n/2<<"\t";

    cout<<"\t"<<n/2<<"+"<<n<<"="<<n+n/2;

    cout<<"\t"<<n/2<<"+"<<n<<"+"<<n+n/2<<"="<<n+n+n;

    cout<<"\t"<<n/2<<"+"<<n<<"+"<<n+n/2<<"+"<<n+n<<"="<<n+n+n+n+n;



    cout<<endl;


    system("PAUSE");
    return 0;
    }




    2 = 2 2 + 4 = 6 2 + 4 +6=12 2+4+6+8=20

    2 = 2
    2+4=6
    2+4+6=12
    2+4+6+12=20

    I don't understand what you are trying to do. Make line breaks??

    Code:
    std::cout << "asdf" << std::endl << "hello"; //maybe the *best* method, not sure
    or 
    std::cout << "asdf" << "\n" << "hello"; //not a good method at all
    or 
    std::cout << "asdf\nhello"; //my preferred method, it's easiest
    output:
    Code:
    asdf
    hello

    first of all, don't post a new thread on the same program

    second of all, why don't you PUT IN 5 AND SEE FOR YOURSELF.

    THIRD,
    we have no freakin clue what's going to happen cause all we see is output, do you even know what you're doing? Read the rules man, I know of 2 that you're violating.

    >>first of all, don't post a new thread on the same program
    Merged by me.
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]

    yes you did, the mods combined em just recently (my post was pushed out of order but still)
    all that was different was you multiplying or something, same basic program, don't nitpick.

    second, here's your exact post that got moved to this thread
    Enter n: 4


    6 * 7 = 42
    66 * 67 = 4422
    666*667= 444222
    6666*6667= 44442222


    i wonder if i enter 5? or 6 what will happen..anyone got instruction to do it?
    what is that??
    no code, no nothing, i was reading what was written, that's all there was.

    third
