#include <iostream>
int main()
{
 std::cout << "Hello, world!\n";
}

This program uses the C++ standard library to write a Hello World program. It is incredibly simple to the syntax of C, the major difference in this example being printf instead being std::cout << (std::cout stands for something, but I can't find info. I think cout stands for C output but I am not sure)

Comments in C++ are identical to comments in C.

// This is a single line comment
/* This
is a multiline
comment */
/* Multi-line comments
* can also
* be written
* like this */

break;

To this day, I am still not entirely sure what the break keyword does, but most languages support it.

x = int(1)
if (x == 0) {
	bool isZeroBool = (true);
} else {
	bool isZeroBool = (false);
}

This is a pretty bad example.

One of the major differences between C and C++ is the inclusion of classes. There is a reason why C++ is commonly called C with classes

class superClass() {
	int main() {
		std::cout << "Superclass says: Hello World!";	
	}
	return main();
}

In C++, the Boolean keyword is shortened to bool for this example, I expect you to know the basics of what a Boolean is (a true or false value, yes or no, 1 or 0)

input1 = string(input("Do you think C++ is good? y/N)"));
if input1 == "y" or "Y" {
	bool trueFalse = true;
} else {
	bool trueFalse = false;
}
std::cout << "You entered: " + trueFalse()

// This program exponentiates 2 and 16. The result should be 65536
int x = 2;
int y = 16;
cout << x ** y;

}

This example is a slightly modified copy of the class section

I have much more to list here, and much to learn.
