*1. Introduction*
C++ is a general-purpose programming language developed by Bjarne Stroustrup.
*2. Variables and Data Types*
```
int x = 10; // integer variable
double y = 20.5; // floating-point variable
char z = 'A'; // character variable
bool isAdmin = true; // boolean variable
```
*3. Operators*
Arithmetic: `+`, `-`, `*`, `/`, `%`
Comparison: `==`, `!=`, `<`, `>`, `<=`, `>=`
Logical: `&&`, `||`, `!`
Assignment: `=`, `+=`, `-=`, `*=`, `/=`, `%=`
*4. Control Structures*
```
if (x > 10) {
cout << "x is greater than 10" << endl;
}
for (int i = 0; i < 5; i++) {
cout << i << endl;
}
```
*5. Functions*
```
int add(int x, int y) {
return x + y;
}
int main() {
int result = add(5, 10);
cout << "Result: " << result << endl;
return 0;
}
```
*6. Arrays and Vectors*
```
int arr[5] = {1, 2, 3, 4, 5};
vector<int> vec = {1, 2, 3, 4, 5};
```
*7. Classes and Objects*
```
class Car {
private:
string color;
public:
Car(string c) {
color = c;
}
void printColor() {
cout << color << endl;
}
};
int main() {
Car myCar("Red");
myCar.printColor();
return 0;
}
```
*8. Pointers*
```
int x = 10;
int* ptr = &x;
cout << *ptr << endl;
```
*9. File Input/Output*
```
#include <fstream>
int main() {
ofstream file("example.txt");
file << "Hello, World!";
file.close();
return 0;
}
```
*10. Conclusion*

Here's an advanced C++ programming topics tutorial:
*Topics*
1. Templates
2. Exception Handling
3. Multithreading
4. Smart Pointers
5. Move Semantics
6. Lambda Expressions
7. Function Objects
8. Binders
9. Type Traits
10. SFINAE (Substitution Failure Is Not An Error)
*1. Templates*
- Function templates
- Class templates
- Template metaprogramming
Example:
```
template <typename T>
T max(T a, T b) {
return (a > b) ? a : b;
}
```
*2. Exception Handling*
- Try-catch blocks
- Exception classes
- std::exception
- Custom exceptions
Example:
```
try {
// code that may throw an exception
} catch (const std::exception& e) {
// handle the exception
}
```
*3. Multithreading*
- std::thread
- std::mutex
- std::lock_guard
- std::condition_variable
Example:
```
std::thread t([]{
// thread function
});
t.join();
```
*4. Smart Pointers*
- std::unique_ptr
- std::shared_ptr
- std::weak_ptr
Example:
```
std::unique_ptr<int> ptr(new int(5));
```
*5. Move Semantics*
- std::move
- std::forward
- Rvalue references
Example:
```
std::string str = "hello";
std::string movedStr = std::move(str);
```
*6. Lambda Expressions*
- Captureless lambdas
- Capturing lambdas
- Generic lambdas
Example:
```
auto lambda = [](int x) { return x * x; };
```
*7. Function Objects*
- std::function
- Function pointers
- Functors
Example:
```
std::function<int(int)> func = [](int x) { return x * x; };
```
*8. Binders*
- std::bind
- std::placeholders
Example:
```
auto boundFunc = std::bind(func, 5);
```
*9. Type Traits*
- std::is_same
- std::is_base_of
- std::is_convertible
Example:
```
std::is_same<int, int>::value // true
```
*10. SFINAE*
- Substitution failure
- std::enable_if
- std::disable_if
Example:
```
template <typename T>
auto func(T t) -> std::enable_if_t<std::is_same<T, int>::value> {
// code
}
```
