Nested conditional execution in C Sharp (C#) - Mini Project: Build & Apply

Nested Conditional Execution

📖 Scenario: You are creating a simple program to help a coffee shop decide the price of a coffee order based on the size and whether the customer wants extra syrup.

🎯 Goal: Build a program that uses nested if statements to determine the final price of a coffee order based on size and syrup option.

📋 What You'll Learn

Create a variable size with the exact value "medium".

Create a variable extraSyrup with the exact value true.

Use nested if statements to set the price variable based on size and extraSyrup.

Print the final price using Console.WriteLine.

💡 Why This Matters

🌍 Real World

Coffee shops and many other businesses use nested conditions to calculate prices based on options customers choose.

💼 Career

Understanding nested conditional execution is essential for programming tasks like pricing, form validation, and decision-making in software.

1

Create initial variables

Create a string variable called size and set it to "medium". Create a boolean variable called extraSyrup and set it to true.

C Sharp (C#)

// Your code here

Need a hint?

Use string size = "medium"; and bool extraSyrup = true; to create the variables.

2

Add price variable

Create a double variable called price and set it to 0.

C Sharp (C#)

string size = "medium";
bool extraSyrup = true;
// Your code here

Need a hint?

Use double price = 0; to create the price variable.

3

Use nested if statements to set price

Use nested if statements with size and extraSyrup to set price as follows:
- If size is "small", price is 2.0, add 0.5 if extraSyrup is true.
- If size is "medium", price is 3.0, add 0.5 if extraSyrup is true.
- If size is "large", price is 4.0, add 0.5 if extraSyrup is true.

C Sharp (C#)

string size = "medium";
bool extraSyrup = true;
double price = 0;
// Your code here

Need a hint?

Use nested if inside each size check to add 0.5 if extraSyrup is true.

4

Print the final price

Use Console.WriteLine to print the text "Final price: " followed by the price variable.

C Sharp (C#)

string size = "medium";
bool extraSyrup = true;
double price = 0;

if (size == "small")
{
    price = 2.0;
    if (extraSyrup)
    {
        price += 0.5;
    }
}
else if (size == "medium")
{
    price = 3.0;
    if (extraSyrup)
    {
        price += 0.5;
    }
}
else if (size == "large")
{
    price = 4.0;
    if (extraSyrup)
    {
        price += 0.5;
    }
}
// Your code here

Need a hint?

Use Console.WriteLine("Final price: " + price); to print the result.
