Programming Tip of the Day – Too many parameters

Avoid passing too many parameters to a method.  If you are forced to pass too many parameters, you are either missing a structure or an object.


For eg.


StoreStudentData(int rollnum, string firstname, string lastname, string class, string section, string[] marks)



can be defined better as

struct StudentInfo


int rollnum;

string firstname;

string lastname;

string class;

double[] marks;


StoreStudentInfo(studinfo) //Here studinfo is a struct variable, which can hold these values.



Advantage is all parameters are contained in a group (using struct) and this can be easily extended to an array of students also.
