void setup() {
// put your setup code here, to run once:

}

void loop() {
// put your main code here, to run repeatedly:

}
int main(){
}; int x
int a;
int b;
int c;

x=0;
a=0;
b=0;
c=1;

a=b+c;
b=c;
c=a;
x=x+1;
when x>5;
return 0;
}
exit status 1
expected initializer before 'int'
this error occurs before int a
Can anyone help

Your error is because there's no semicolon after "int x", but that's the least of your problems.

I found this

The posted code just needs a little syntax cleanup:

int x;
int a;
int b;
int c;

void setup() {
  // put your setup code here, to run once:
 x=0;
 a=0;
 b=0;
 c=1;
// maybe Serial.begin(9600);
}

void loop() {
  // put your main code here, to run repeatedly:

 a=b+c;
 b=c;
 c=a;
  x=x+1;

 // maybe Serial.println (a);  // want to see some output?
   if (x<6){
  // make another pass thru loop
  }
  else {
  while(1); // do nothing until reset is pressed
  }
}

Thanks! what does serial mean? and also what is serial.begin(9600)? Thanks

Serial.begin() and Serial.print() or Serial.println() are how you display stuff on the Serial monitor in the IDE.

7

Thanks! however, the line a=b+c says that a does not specify a type.

We can't see your code.

int x;
int y;
int b;
int c;
void setup() {
// put your setup code here, to run once:
x=0;
y=0;
b=0;
c=1;
}

void loop() {
// put your main code here, to run repeatedly:

}y=b+c;
b=c;
c=y;
x=x+1;
when (x<6);{
return 0;

Serial.println(y)
else{
while(1);
}

the problem is that y=b+c is returning error y does not name a type

10

The } just in front of the y ends loop() and so everything from there onwards is not in any function.

11

int x;
int y;
int b;
int c;
void setup() {
// put your setup code here, to run once:
x=0;
y=0;
b=0;
c=1;
}

void loop() {
// put your main code here, to run repeatedly:

y=b+c;
b=c;
c=y;
x=x+1;
if (x<6);{
return 0;

Serial.println(y)
;}
else{
while(1);
}

it is now returning that else has no if. why would this occur?

if (x<6);{

You should look up the syntax of if (and C++ in general).

Starting late on the homework?

Some general tips:

  • use sensible variable names
  • use Serial.begin() if you want to use Serial
  • put code to run once into setup
  • only make variables global if they have to be shared
  • don't try to return values from void functions
