Operator precedence and evaluation order in C Sharp (C#) - Mini Project: Build & Apply

Operator precedence and evaluation order

📖 Scenario: You are creating a simple calculator program that evaluates expressions with multiple operators. Understanding how C# decides which operation to do first is important to get the right answer.

🎯 Goal: Build a small program that shows how operator precedence and evaluation order affect the result of an expression.

📋 What You'll Learn

Create variables with specific values

Add a configuration variable to change the expression

Write an expression using multiple operators to see precedence

Print the final result to the console

💡 Why This Matters

🌍 Real World

Understanding operator precedence helps you write correct calculations in programs like calculators, games, or financial software.

💼 Career

Many programming jobs require you to write expressions that combine multiple operations correctly and efficiently.

1

Create initial variables

Create three integer variables called a, b, and c with values 5, 10, and 2 respectively.

C Sharp (C#)

// Your code here

Need a hint?

Use int to declare each variable and assign the exact values given.

2

Add an operator expression selector

Create a string variable called operation and set it to "mixed" to choose the type of expression to evaluate.

C Sharp (C#)

int a = 5;
int b = 10;
int c = 2;
// Your code here

Need a hint?

Use string to declare operation and assign the exact text "mixed".

3

Write the expression using operator precedence

Create an integer variable called result and assign it the value of the expression a + b * c. This will show how multiplication happens before addition.

C Sharp (C#)

int a = 5;
int b = 10;
int c = 2;
string operation = "mixed";
// Your code here

Need a hint?

Remember multiplication * happens before addition + in C#.

4

Print the result

Write a line to print the value of result to the console using Console.WriteLine.

C Sharp (C#)

int a = 5;
int b = 10;
int c = 2;
string operation = "mixed";
int result = a + b * c;
// Your code here

Need a hint?

Use Console.WriteLine(result); to show the final number.
