#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;

std::cout << "Newline?\nNewline! Tab?\tTab! Quotation Marks?\"Quotation Marks\" ";

This example is a slightly modified copy of the class
section

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