Please help newbie:

Aug 27th, 2007

I need to display 1, 1, 2, 3, 5, 8, 13, 21, 34, 55 … I “must” use the “for” …This is what I have but it only counts by two. I don’t want the answer…however can you please give me some clues on the proper way to add the prior two numbers to get the needed sum?

Have 2 variables outside the for loop. These two variables will contain the first 2 values. Display them. Inside the loop add these two variables which will result in third variable. Display the third variable's value. Once added and displayed, move second variable value to first variable, and move third variable value to second variable. The for loop condition should check for the last value of the third variable.

Hope this clarifies your query!!!!!

#include <iostream>

using std::cout;
using std::endl;

//
int main()
{
int count = 0;

for ( int count = 1; count <= 55; count = count + 2)
cout << count << endl;

return 0;
} //end of main function

Take a look at http://en.wikipedia.org/wiki/Fibonacci_number

eg code :

first = 0;
second = 1;
cout << first;
cout << second;

This should come before the for loop.

inside the for loop :

third = first + second;
count << third;
first = second;
second = third;

the for loop should be

for(;third<=55

check with your code with these changes.....

If you learnt how to draw a flow chart you could then use that to convert into code.

Flow charts help to visualise how problems such as these are solved.

what are the errors. maybe you need to add braces { and } around lines 21, 22 and 23 to make them all part of the loop.

Don't PM me with questions -- you might get a nasty PM in response. If you have a question then post it in one of the forums.
