Solidity is the primary language for Ethereum blockchain development. It offers developers the tools to build decentralized applications and smart contracts. Understanding Solidity opens doors to the world of blockchain technology.

In this course, you’ll explore Ethereum and Solidity programming’s fundamentals. You’ll then learn about the data types, constructors, variables, operators, conditional statements, and loops. This lays the groundwork for understanding Solidity’s data structures, including strings, arrays, mappings, structs, and enums. Toward the end of the course, you’ll cover functions, common patterns in smart contract development, and advanced topics such as inheritance and interfaces.

Upon completing the course, you’ll have a solid understanding of Solidity and its application in the Ethereum ecosystem. You’ll have the skills to develop, deploy, and manage smart contracts. This will pave the way for a career in blockchain technology and decentralized application development.

Introduction to the Solidity Programming Language

How do we declare a string in Solidity?

How do we declare an array with a fixed length of five?

How do we declare an array with a fixed length of five?

Can we resize a mapping in Solidity?

```
struct Person(string name, uint age);
```

```
struct Person { string name; uint age; }
```

```
struct { string name; uint age; } Person;
```

```
Person struct = { string name; uint age; }
```

How do we define a struct named `Person` with `name` and `age` as member variables?

How do we define a struct named <code>Person</code> with <code>name</code> and <code>age</code> as member variables?

```
enum Status { Active, Inactive };
```

```
enum { Active, Inactive } Status;
```

```
enum Status = { Active, Inactive };
```

How do we define an enum named `Status` with the `Active` and `Inactive` states in Solidity?

How do we define an enum named <code>Status</code> with the <code>Active</code> and <code>Inactive</code> states in Solidity?
