//use nouns not verbs for variables.

//way better than

//lists 
//if you are naming single variable represents the marks as "mark" 
//so naming the list of marks as 
double[] mark_list;

//mostly better than writing it as
double[] marks;


///// variable names - naming booleans /////
//bad
bool male = true;
bool car_owner = false;

//better to imply types
bool is_male; 
bool has_car; 

//However it is kinda common to name the counters in loops for example
// as i and j .. for this purpose it is fine.
for(i=0; i<product_list_size ; i++)
  //do some thing

//functions - use verbs for naming 
//function name along with its paramters should be as much self-descriptive as possible.

// the in_list is not useful here. It is clear as it is taking a list
//and a number
