Problem with Fibonacci Sequence Calculation

Question

I am doing an exercise that is to return the Fibonacci Sequence in C language up to a certain number informed by the user. The problem is that the program instead of calculating up to that number, it performs one more sequence calculation. For example, I typed that I want up to number 50 and it calculates up to 55, if I type that I want up to number 10 it calculates up to 13.

void calculoFibonacci(int);

int main(){

  int numeroFinal;

  printf("Digite ate que numero voce deseja calcular : ");
  scanf("%d",&numeroFinal);

  calculoFibonacci(numeroFinal);

 system("pause");
 return 0;
}

void calculoFibonacci(int num){
   int antecessor = 0, sucessor = 1, auxiliar;

   for (auxiliar = 0; auxiliar <= num;){
      auxiliar = antecessor + sucessor;
      printf("%d \n",auxiliar);
      antecessor = sucessor;
     sucessor = auxiliar;
}
}

Answer 1

basically the problem is in the last execution of the for, as its pro condition is ending depends on a calculation and not only the increment of one by one, it may occur of the calculation to overcome the condition, for example:

for(auxiliar = 0; 34 <= 50;) //verdade
    auxiliar = 21 + 34;
    printf("55");

that is to stop the loop if it is larger q o num, then uses a if(...) break

    while(auxiliar <= num)
    {
        antecessor = sucessor;
        sucessor = auxiliar;
        auxiliar = antecessor + sucessor;
        if(auxiliar > num) break;
        printf("%d \n", auxiliar);

    }
