Single-dimensional array declaration in C Sharp (C#) - Mini Project: Build & Apply

Single-dimensional array declaration

📖 Scenario: You are creating a simple program to store the names of fruits in a list. This list will help you keep track of fruits you want to buy from the market.

🎯 Goal: Build a program that declares a single-dimensional array of fruits, sets a size for it, fills it with fruit names, and then prints all the fruit names.

📋 What You'll Learn

Declare a single-dimensional array of strings called fruits with size 4

Assign the fruit names "Apple", "Banana", "Cherry", and "Date" to the array elements

Use a for loop with variable i to iterate over the array

Print each fruit name inside the loop using Console.WriteLine

💡 Why This Matters

🌍 Real World

Arrays are used to store lists of items like names, prices, or scores in many programs.

💼 Career

Knowing how to declare and use arrays is a basic skill for software developers working with data collections.

1

Declare a single-dimensional array

Declare a single-dimensional array of strings called fruits with size 4.

C Sharp (C#)

// Your code here

Need a hint?

Use string[] fruits = new string[4]; to create an array that can hold 4 fruit names.

2

Assign fruit names to the array

Assign the fruit names "Apple", "Banana", "Cherry", and "Date" to the array elements fruits[0], fruits[1], fruits[2], and fruits[3] respectively.

C Sharp (C#)

string[] fruits = new string[4];
// Your code here

Need a hint?

Assign each fruit name to the correct index in the array using fruits[index] = "FruitName";.

3

Use a for loop to iterate over the array

Use a for loop with variable i to iterate over the fruits array from index 0 to 3.

C Sharp (C#)

string[] fruits = new string[4];
fruits[0] = "Apple";
fruits[1] = "Banana";
fruits[2] = "Cherry";
fruits[3] = "Date";

// Your code here

Need a hint?

Use for (int i = 0; i < fruits.Length; i++) to loop through all elements.

4

Print each fruit name

Inside the for loop, use Console.WriteLine(fruits[i]) to print each fruit name.

C Sharp (C#)

string[] fruits = new string[4];
fruits[0] = "Apple";
fruits[1] = "Banana";
fruits[2] = "Cherry";
fruits[3] = "Date";

for (int i = 0; i < fruits.Length; i++)
{
    // Your code here
}

Need a hint?

Use Console.WriteLine(fruits[i]); inside the loop to print each fruit.
