Errors overloading "<<" and ">>" functions...

jcbrunelle13 (4)
Doing a program for adding, subtracting, multiplying, and comparing two complex numbers and printing the results. I'm pretty sure my syntax is correct, but the occurring errors are preventing me from finishing the rest of my program. My program is as follows. If anyone has anything to offer it would be greatly appreciated. I'm at a loss right now. Sorry if this appears slightly disorganized.

friend ComplexNumber operator *(const ComplexNumber& firstamt, const ComplexNumber& secamt);
friend ostream& operator <<(ostream& outs, const ComplexNumber& thevalue);
friend istream& operator >>(istream& ins, ComplexNumber& avalue);

You need to include the appropriate header <istream> and <ostream> before the declaration of class ComplexNumber
