Array initialization in C - Mini Project: Build & Apply

Array initialization

📖 Scenario: You are helping a small store keep track of the prices of five popular fruits. You want to store these prices in a simple list so you can use them later for calculations.

🎯 Goal: Create an array to hold the prices of five fruits, then print all the prices one by one.

📋 What You'll Learn

Create an array called prices with exactly five float values: 1.20, 0.50, 0.75, 2.00, and 1.50

Create an integer variable called i for looping

Use a for loop with i from 0 to 4 to print each price on its own line using printf

💡 Why This Matters

🌍 Real World

Arrays are used to store lists of related data like prices, scores, or measurements in many programs.

💼 Career

Understanding arrays and loops is essential for programming tasks in software development, data processing, and embedded systems.

1

Create the array of prices

Create a float array called prices with these exact values: 1.20, 0.50, 0.75, 2.00, and 1.50

C

#include 

int main() {
    // Create the float array prices with 5 values

    return 0;
}

Need a hint?

Use the syntax: float prices[5] = {value1, value2, value3, value4, value5};

2

Add a loop counter variable

Add an integer variable called i to use as a counter for looping

C

#include 

int main() {
    float prices[5] = {1.20, 0.50, 0.75, 2.00, 1.50};
    // Declare int variable i for loop

    return 0;
}

Need a hint?

Write int i; inside main() before the loop.

3

Use a for loop to print each price

Use a for loop with i from 0 to 4 to print each price from the prices array on its own line using printf

C

#include 

int main() {
    float prices[5] = {1.20, 0.50, 0.75, 2.00, 1.50};
    int i;
    // Add a for loop to print each price

    return 0;
}

Need a hint?

Use for (i = 0; i < 5; i++) and inside the loop printf("%.2f\n", prices[i]);

4

Print the prices to see the output

Run the program to print all the prices stored in the prices array, each on its own line

C

#include 

int main() {
    float prices[5] = {1.20, 0.50, 0.75, 2.00, 1.50};
    int i;
    for (i = 0; i < 5; i++) {
        // Print each price
    }
    return 0;
}

Need a hint?

Make sure your printf prints each price on its own line with two decimals.
