	string father_name;
	string id_no;
	int    age;
	string gender;
	string religion;
	int semester;
   string course;
   string code;
   string c_hrs;
   double marks;
   
public:
	student():name(),father_name(),id_no(),age(),gender(),religion(),semester()
	{}
    student(string n,string fn,string id,int a,string g,string r,int sem):name(n),father_name(fn),id_no(id),age(a),gender(g),religion(r),semester(sem)
	{}
	student(string n,string id,string c,double m):name(n),id_no(id),course(c),marks(m)
	{}

Welcome to Daniweb!

I have a few suggestion that will help you get the help you need.

1) Please use code tags. It will help everyone read your code.

2) Try not to post hundreds of lines of code. Each line takes the reader time to analyze, so you should try to post only lines that are relevant to your question.

3) Try to "abstract" your question into a c++ question. That is, rather than "How do I search for a student?", instead say "How do I find a string in a a vector of strings?" or something similar.

Good luck,

Dave
