hey fellas im im having this error "expected declaration before "}" token" on line 33
im using code:blocks and when i try to fix that i return nothing on the output

  #include <iostream>
#include <array>

using namespace std;

int primeD (int b){

    for (int i = 2; i < b; i++)
    {
        if (b % i == 0){

            return i;

        }


    }
}


bool prime (int a)
{
    for (int i = 2; i < a; i++)
    {
        if (a % i == 0)
        {
            return false;
            else
            return true;
        }

    }
}




int fibonacci (int f)
{
    int c;
    int fib [1000];
    fib [0] = 0;
    fib [1] = 1;

    for (int i = 2; i < 1000; i++)
    {
        fib[i] = fib[i-1] + fib[i-2];
        if(fib[i] > f)
        {

            c = fib[i];
            loop:
            fib[i] = fib[i-1] + fib[i-2];
            c = fib[i];
            while(!prime(c))
            {
                goto loop;
            }
            return c;

        }



        }
}



int main() {
    int a = 227000;
    while(prime(fibonacci(a)))
    {
        a = (fibonacci (a));


    }

    cout << a;


}

for (int i = 2; i < a; i++)
    {
        if (a % i == 0)
        {
            return false;
            else
            return true;
        }

    }

The else statement is inside the if statement. It should be:

for (int i = 2; i < a; i++)
    {
        if (a % i == 0)
            return false;
        else
            return true;
    }

Why my program dont Print out the next prime number
Of 227300 and instead return 227300

[kevinkjt2000]

Because the logic in the for loop is incorrect.

for (int i = 2; i < a; i++)
    {
        if (a % i == 0)
            return false;
        else
            return true;
    }

So say I passed 9 into the function the first thing that happens is the if will have

if(9 % 2 == 0)

which is false, so it will execute the else and return true. 9 is not prime, so this function should not be returning true with 9 as an input. I have not looked at your fibonacci function yet. Hopefully there is nothing wrong with the fibonacci function.
