ok im writing this program for my c++ class, were supposed to aks the user how many times he wants the fibonacci sequence done. BUT i keep getting this error-
fib prog.obj : error LNK2005: _main already defined in 12.obj
Debug/p363.exe : fatal error LNK1169: one or more multiply defined symbols found

heres my code-

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

//function declarations

int GetData();
void CalcFib(int seq);

int main()
{
	int seq;
	seq=GetData();
	system ("CLS");
	CalcFib(seq);
	return 0;
}
int GetData()
{
	/*
	task:obtain 3 of times sequence must be done
	Data in: nada
	Data out: uno interger
	*/
	int seq;
	do
	{
		cout<<"Enter ho wmany times you want the sequence done. "<<endl;
		cin>>seq;
		if(seq<0)
		{
			system("cls");
			cout<<"YOU ENTERED A NEGATIVE NUMBER"<<endl;
		}
	}
	while(seq<0);
	return seq;
}
void CalcFib(int seq)
{
	/*
	task: display the sequence
	Data in:# of desired sequences
	Data out:nada
	*/
	int x, num1, num2, num3, nada;
	num1=0;
	num2=1;
	cout<<"the number of times the sequence was done" << seq<<endl;
	if(seq==1)
		cout<<"0"<<endl;
	else if(seq==2)
		cout<< " " <<num1 << " " << num2;
	else
	{
		cout<<" "<< num1 << " " << num2 << " ";
	for(x=1; x<=(seq-2); x++)
		{
			num3=num1+num2;
			cout<<num3<<endl;
			nada=num2;
			num2=nada;
		}
	}
	cout<<endl<<endl;
	
}

man your code needs spaces and tabs to make it readable. I will see what I can find for ya

 

[metallica0421]

it does have spaces and tabs but when i posted it it screwed it up, if i click edit it shows up with spaces and tabs

 

[Thelemac]

Use teh code tags (which I put around it for ya. )

 

[metallica0421]

thx thelmac, ill be sure to do that in the future

 

[Thelemac]

Sure you don't have other things that you're trying to link that with? Other files in the workspace if you're using Visual C++, or not being selective enough with your link statement if you're using something like gcc

 

[metallica0421]

oops hehe, i had another file on the same project, i got rid of it and now it runs BUT........the fibonacci sequence doestn turn our right, i type in 10, and i get 0 1111111111, when what i shuld get is 0 1 1 2 3 5 8 13 21 34

 

[jreinsma]

it is your nada here is how it should look.....

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

//function declarations

int GetData();
void CalcFib(int seq);

int main()
{
int seq;
seq=GetData();
system ("CLS");
CalcFib(seq);
return 0;
}

int GetData()
{
/*
taskbtain 3 of times sequence must be done
Data in: nada
Data out: uno interger
*/
int seq;
do
{
cout<<"Enter ho wmany times you want the sequence done. "<<endl;
cin>>seq;
if(seq<0)
{
system("cls");
cout<<"YOU ENTERED A NEGATIVE NUMBER"<<endl;
}
}
while(seq<0);
return seq;
}

void CalcFib(int seq)
{
/*
task: display the sequence
Data in:# of desired sequences
Data out:nada
*/
int x, num1, num2, num3, nada;
num1=0;
num2=1;
cout<<"the number of times the sequence was done" << seq<<endl;
if(seq==1)
cout<<num1<<endl;
else if(seq==2)
cout<< " " <<num1 << " " << num2;
else
{
cout<<" "<< num1 << " " << num2;
for(x=1; x<=(seq-2); x++)
{
num3=num1+num2;
cout<<" " << num3;
num1=num2;
num2=num3;
}
}
cout<<endl<<endl;

}

 

[jreinsma]

darn they did take the tabs out!!! you need to take num2 and assign it to num1 then assign num3 to num2 instead of using the variable nada

 

[jreinsma]

so just take a look at the loop in your function

 

[metallica0421]

yep that did it, thx allot for the help guys/gals
