Assignment operators in C - Mini Project: Build & Apply

Using Assignment Operators in C

📖 Scenario: You are managing a small store's inventory. You want to update the stock counts efficiently using assignment operators.

🎯 Goal: Learn how to use assignment operators like =, +=, -=, *=, and /= to update variables in C.

📋 What You'll Learn

Create integer variables with exact initial values

Use assignment operators to update these variables

Print the final values to see the changes

💡 Why This Matters

🌍 Real World

Stores and businesses often update inventory counts quickly using assignment operators in their software.

💼 Career

Understanding assignment operators is essential for writing efficient and readable code in many programming jobs.

1

Create initial stock variables

Create three integer variables called apples, oranges, and bananas with values 50, 30, and 20 respectively.

C

# Create integer variables apples, oranges, and bananas with values 50, 30, and 20
// Your code here

Need a hint?

Use the syntax int variable_name = value; to create variables.

2

Add new stock using += operator

Add 10 to apples and 5 to oranges using the += assignment operator.

C

int apples = 50;
int oranges = 30;
int bananas = 20;

// Add 10 to apples and 5 to oranges using +=
// Your code here

Need a hint?

The += operator adds a value to the variable and updates it.

3

Remove some bananas using -= operator

Subtract 7 from bananas using the -= assignment operator.

C

int apples = 50;
int oranges = 30;
int bananas = 20;
apples += 10;
oranges += 5;

// Subtract 7 from bananas using -=
// Your code here

Need a hint?

The -= operator subtracts a value from the variable and updates it.

4

Print the final stock counts

Use printf to print the values of apples, oranges, and bananas each on a new line with the exact format:
Apples: 60
Oranges: 35
Bananas: 13

C

int apples = 50;
int oranges = 30;
int bananas = 20;
apples += 10;
oranges += 5;
bananas -= 7;

// Print the final values of apples, oranges, and bananas
// Your code here

Need a hint?

Use printf("Label: %d\n", variable); to print each variable with its label.
