Welcome to the C++ to Cco Transition & Architecture Guide. This document parallels standard C++ programming paradigms (OOP, Streams, RAII, Smart Pointers, Containers, Templates, Lambdas, Move Semantics) with their modern, memory-safe, Pythonic equivalents in Cco.
In C++, standard console output uses stream operators from <iostream> (std::cout << "Hello" << std::endl;). In Cco, the built-in print() function outputs clean, newline-terminated text directly.
#include <iostream>
int main() {
std::cout << "Hello World from C++ & Cco!" << std::endl;
return 0;
}// codebase/218_cpp_hello_world_cout.cco
fn main() -> int {
print("Hello World from C++ & Cco!");
return 0;
}
Run: ./cco codebase/218_cpp_hello_world_cout.cco --run
Output:
Hello World from C++ & Cco!
In modern C++ (C++11/C++14/C++17), auto allows the compiler to deduce variable types at compile time. In Cco, let provides full compile-time type deduction with clean, Pythonic syntax.
#include <iostream>
#include <string>
int main() {
auto age = 25;
auto salary = 75000.50;
std::string name = "Alice";
const double PI = 3.14159;
std::cout << "Employee: " << name << "\n";
std::cout << "Age: " << age << "\n";
return 0;
}// codebase/219_cpp_variables_and_auto_types.cco
fn main() -> int {
let age = 25;
let salary = 75000.50;
let name = "Alice";
let pi: float = 3.14159;
print("=== C++ Auto Types & Constants vs Cco ===");
print(f"Employee: {name}");
print(f"Age: {age}");
print(f"Salary: {salary}");
print(f"Constant Pi: {pi}");
return 0;
}
Run: ./cco codebase/219_cpp_variables_and_auto_types.cco --run
Output:
=== C++ Auto Types & Constants vs Cco ===
Employee: Alice
Age: 25
Salary: 75000.5
Constant Pi: 3.14159
In C++20, string formatting requires #include <format> and std::format("{}", val). In Cco, first-class interpolated f-strings (f"Product: {product}, Price: ${price}") format dynamic variables natively with automatic type conversion and zero memory leaks.
#include <iostream>
#include <format>
#include <string>
int main() {
std::string product = "Laptop";
double price = 999.99;
int stock = 15;
std::string summary = std::format("{} costs ${:.2f} with {} in stock.", product, price, stock);
std::cout << summary << std::endl;
return 0;
}// codebase/220_cpp_strings_and_formatting.cco
fn main() -> int {
let product = "Laptop";
let price = 999.99;
let stock = 15;
print("=== C++ std::string & std::format vs Cco f-strings ===");
print(f"Product: {product}");
print(f"Price: ${price}");
print(f"Stock Remaining: {stock} units");
print(f"Inventory Summary: {product} costs ${price} with {stock} units in stock.");
return 0;
}
Run: ./cco codebase/220_cpp_strings_and_formatting.cco --run
Output:
=== C++ std::string & std::format vs Cco f-strings ===
Product: Laptop
Price: $999.99
Stock Remaining: 15 units
Inventory Summary: Laptop costs $999.99 with 15 units in stock.
The fundamental leap from C to C++ was the introduction of Classes and Objects. Cco adopts this object-oriented model with clean Pythonic method binding (self) and native memory safety.
#include <iostream>
#include <string>
class Car {
public:
std::string brand;
std::string model;

std::cout << "Braking: " << brand << " speed slowed to " << speed << " km/h\n";
}
};

my_car.accelerate(50);
my_car.accelerate(30);
my_car.brake(40);
return 0;
}
Run: ./cco codebase/221_cpp_intro_procedural_vs_oop.cco --run
Output:

In C++, a minimal program requires #include <iostream>, namespace imports (using namespace std;), and stream piping (cout << "Hello World!";). In Cco, it is a single self-contained function fn main() -> int.
#include <iostream>
using namespace std;
int main() {
cout << "Hello World!";
return 0;
}// codebase/222_cpp_get_started_first_program.cco
fn main() -> int {
print("Hello World!");
return 0;
}
Run: ./cco codebase/222_cpp_get_started_first_program.cco --run
Output:
Hello World!

In C++, namespaces (namespace Math { ... }) provide zero-overhead compile-time naming scopes to prevent global symbol collisions without instantiating objects or holding state (Math::add(a, b)).
Honest Language Note: Cco does not currently have
namespacekeyword blocks or::scope resolution. Instead, Cco uses a single, flat global namespace across files combined with whole-program AST module imports (import "...";). Free functions are organized using modular files and clear naming prefixes (e.g.math_add()), reserving classes only for cases where instance state is actually needed.
#include <iostream>
namespace Math {
int add(int a, int b) {
return a + b;
}
int multiply(int a, int b) {
return a * b;
}
}
int main() {
std::cout << "=== C++ Namespaces vs Cco Global & Module Scope ===" << std::endl;
std::cout << "Math::add(15, 25) = " << Math::add(15, 25) << std::endl;
std::cout << "Math::multiply(4, 5) = " << Math::multiply(4, 5) << std::endl;
return 0;
}// codebase/224_cpp_namespace_scoping_concept.cco
// In Cco, free functions live in a clean global namespace without C++ `namespace` blocks.
// Symbol organization across files is achieved using `import` and clear naming conventions.
fn math_add(a: int, b: int) -> int {
return a + b;
}
fn math_multiply(a: int, b: int) -> int {
return a * b;
}
fn main() -> int {
print("=== C++ Namespaces vs Cco Global & Module Scope ===");
let sum = math_add(15, 25);
let product = math_multiply(4, 5);
print(f"math_add(15, 25) = {sum}");
print(f"math_multiply(4, 5) = {product}");
return 0;
}
Run: ./cco codebase/224_cpp_namespace_scoping_concept.cco --run
Output:
=== C++ Namespaces vs Cco Global & Module Scope ===
math_add(15, 25) = 40
math_multiply(4, 5) = 20
