My teacher has given my class a program that converts an infix expression like A+B*C into postfix. I have finished the other pieces of code but the overloaded istream operator is giving me some problem. This is the error I'm getting:
error: there are no arguments to 'convertToPostfix' that depen...
The square root calculation could just be done before the loop. Since this value does not change within the function, it doesn't need to be recalculated each time through the loop.
public static boolean isPrime(int num) {
if (num % 2 == 0) return false;
int squareRoot = Math.floor(Math...
As I am trying to understand the concepts of Friend Functions, Overloaded Operators, and Inheritance in C++. I am very confused on the specifics used for coding, since I am fairly new in programming, and working in the Virtual Studio C++ environment in writing code.

Even though it's the first time I'm writing something this "big", it feels like I know C# quite good. It's been nice to learn LINQ also and I am very impressed by the features, and perhaps I have overused it here (if it's possible to do that).

I am experimenting with streams and lambdas in Java 8. This is my first serious foray using functional programming concepts; I'd like a critique on this code.
This code finds the Cartesian product of three sets of ints. My questions/complaints about this snippet are:

I am wondering if this question can be solved in Java (I'm new to the language). This is the code:
class Condition {
// you can change in the main
public static void main(String[] args) {
int x = 0;
if (x == x) {
System.out.println("Ok");
} else {
