## Introduction

This tutorial covers basic operations in C++, including arithmetic, string manipulation, and control structures. Each section includes a minimal example function that can be run in a code cell.

## Arithmetic Operations

### Addition

```cpp
#include <iostream>

int add(int a, int b) {
    return a + b;
}

int main() {
    std::cout << "5 + 3 = " << add(5, 3) << std::endl;
    return 0;
}
```

### Subtraction

```cpp
#include <iostream>

int subtract(int a, int b) {
    return a - b;
}

int main() {
    std::cout << "10 - 4 = " << subtract(10, 4) << std::endl;
    return 0;
}
```

## String Manipulation

### String Concatenation

```cpp
#include <iostream>
#include <string>

std::string concatenate(const std::string& str1, const std::string& str2) {
    return str1 + str2;
}

int main() {
    std::string result = concatenate("Hello, ", "World!");
    std::cout << result << std::endl;
    return 0;
}
```

## Control Structures

### If-Else Statement

```cpp
#include <iostream>

std::string checkNumber(int num) {
    if (num > 0) {
        return "Positive";
    } else if (num < 0) {
        return "Negative";
    } else {
        return "Zero";
    }
}

int main() {
    std::cout << "5 is " << checkNumber(5) << std::endl;
    std::cout << "-3 is " << checkNumber(-3) << std::endl;
    std::cout << "0 is " << checkNumber(0) << std::endl;
    return 0;
}
```

### For Loop

```cpp
#include <iostream>

void printNumbers(int n) {
    for (int i = 1; i <= n; ++i) {
        std::cout << i << " ";
    }
    std::cout << std::endl;
}

int main() {
    std::cout << "Numbers from 1 to 5: ";
    printNumbers(5);
    return 0;
}
```

## Functions

### Function with Multiple Parameters

```cpp
#include <iostream>

int multiply(int a, int b) {
    return a * b;
}

int main() {
    std::cout << "4 * 7 = " << multiply(4, 7) << std::endl;
    return 0;
}
```

Each of these examples demonstrates a basic C++ concept and includes a minimal function that can be run in a code cell. You can copy and paste these code snippets into your development environment to test and experiment with them.
