Thread: Jumping into C++, Chapter 5 Question 1.

Hello. I was just doing the first question of Chapter 5 in Jumping in C++. I completed it but I was just wondering if it was the most effeicent was to do it. And if not, what is it?

The question was: Write a program that prints out the entire lyrics to a full rendition of "99 Bottles of Bear on the Wall".

This was my program I wrote:

Code:

#include <iostream>
#include <string>


usingnamespacestd;


int main()


{
    int j=98;

    for(int i=99;i>2;i--)
    {
cout<<i<<" bottles of beer on the wall, "<<i<<" bottles of beer.\n Take one down pass it around, "<<j<<" bottles of beer on the wall.\n";
        cout<<"\n";
        j--;
    }

    for(int i=2;i>1;i--)
    {
cout<<i<<" bottles of beer on the wall, "<<i<<" bottles of beer.\n Take one down pass it around, "<<j<<" bottle of beer on the wall.\n";
    cout<<"\n";
    }

cout<<"1 bottle of beer on the wall, 1 bottles of beer.\n Take one down pass it around, no more bottle of beer on the wall.\n";

    cout<<"\n";

cout<<"No more bottles of beer on the wall, No more bottles of beer.\n Go to the store but some more, 99 bottle of beer on the wall.\n";
}

If you guys had to write a program for this question. What would you write to get the exact lyrics.

So can you please write out a program that would do this with all the corrections in?

You could do a few things, although I don't really see the point for such a small program. You could use strings or DEFINES to hold the text, you don't need the variable j, you could create a function, you could even use a struct or vector in there, or a constant,

Often there are several ways to get to the outcome, as you are realising a lot of programming is about writing efficient, elegant code. Maybe just keep going onto more significant examples though.

Hodor likes beer. I just drank a 500ml bottle of my home brewed ginger beer. Very nice indeed.
