What would be wrong with not writing returnstatement in a value returing function? Can you have a returnstatement in a void function? Does the return statement in the following function cause syntax error?
void p(double x, double y)
{
cout << x << " " << y << endl;
return x+y;
}
2. Write a function headers (not the bodies) for the following functions;
a. Return a sales commission, given the sales amount and the commission rate.
b.Display the calendar for a month, given the month and year.
c.Return a square root of number.
d.Test Whether a number is even, and return true if it is.
e.Display a message a specified number of times.
f.Return the monthly payment, given the loan amount, number of years, and annual interest rate.
g.Return the corresponding uppercase letter, given a lowercase letter.
