I get required to write the function collatzVlaue, that when passed an integer, return its collaztvalue, it returns the number of operations it takes to reduce that number to one.

For example: if n=10

10=>5=>16=>8=>4=>2=>1

that means if n%2==0 , I will be divided by 2 whereas It will multiply by 3 and plus 1

when I used loop for to count how many operation the number take, I always get the error "expecting EOF, found 'for'"

plz help me

Your first problem is that your collatzValue function ends before it gets to the for(...) line.
This is because the body of the function should be contained within the {}'s, but it's outside them!

Your next problem is that your for loop is all wrong, and the function you've written won't accomplish what you want anyway.

Here is a working example that uses recursion to do the work.

int collatzValue( int n ) {
if ( n == 1 ) {
return( 1 );
}
if ( n%2 == 0 ) {
return( 1 + collatzValue( n / 2 ) );
}
return( 1 + collatzValue( ( 3 * n ) + 1 ) );
}
void setup() {
print( "10 :: " + collatzValue(10) );
}
void draw() {
}

Side note: you show big pictures of textual data, unreadable without clicking on them, cannot be copied nor searched.

Just use copy & paste of the text in this forum, to show some code (or console output)!
Thanks.
