hi, im new to arduino, and when i compile my code the next error appears it says that expected initializer before void function, i've already read in the web and says that maybe i need a semicolon but i cant find where  
my code is the next, i would appreciate if you could tell my where my error is.

//constantes para pines  
const int xpin = A0; //pin x  
const int ypin = A1; //pin y  
const int zpin = A2; //pin z  
const unsigned int baud\_rate = 9600;  
int x; //variable valor x  
int y; //variable valor y  
int z; //variable valor z  
int contador = 0; //contador de valores  
//valores obtenidos de getval  
int valx1;  
int valy1;  
int valz1;  
int constante=415; //constante para saber el numero que salio  
//diferencias entre constante y valores obtenidos  
int dif1;  
int dif2;  
int dif3;  
int numero

//inicio del serial  
void setup() //  
{  
Serial.begin(baud\_rate); //  
for(contador=0;contador\<2;contador++)  
{  
x = GetValX();  
y = GetValY();  
z = GetValZ();  
}  
}

```cpp
int numero

```

Yes,  
int numero  
needs a ; at the end.

int numero ;

Didn't the IDE also highlight the line for you, or indicate the line number? (looks like line 19)

Easy to miss.  
You'll see those sooner after coding for 6 months 8)
