Ok, I have to create a program that prints whether a number is in the Fibonacci sequence. This is what i have so far, but i could use some help:

I don't know if this is the best way to go about this problem. Also, is there a way for me to use "bool found=false;" or "char found='N';"Code:`#include <iostream>`

#include <iomanip>

using namespace std;

int main (void)

{

int valin, n=0;

cout << "Input a positive integer: " << endl;

cin>> valin;

if (valin==0 || valin==1)

cout << "The number" << valin << "is in the Fibonacci sequence." << endl;

else if (valin==(n-1)+(n-2))

cout << "The number" << valin << "is in the Fibonacci sequence." << endl;

else

cout << "The number" << valin << "in not in the Fibonacci sequence." << endl;

return 0;

}

any help would be appreciated, thanks
