Array Deletion at End in DSA C - Build from Scratch

Array Deletion at End

📖 Scenario: You are managing a list of daily temperatures recorded in a weather station. Sometimes, the last recorded temperature needs to be removed if it was recorded by mistake.

🎯 Goal: Build a program that stores a fixed list of temperatures in an array, keeps track of the number of valid entries, and deletes the last temperature entry by reducing the count.

📋 What You'll Learn

Create an integer array called temperatures with exactly these values: 30, 32, 31, 29, 28

Create an integer variable called count and set it to the number of elements in temperatures

Write code to delete the last element by reducing count by 1

Print the remaining elements in temperatures up to count separated by spaces

💡 Why This Matters

🌍 Real World

Managing lists of data where the last entry might need to be removed, such as undoing the last action or correcting input errors.

💼 Career

Understanding how to manage arrays and their sizes is fundamental for programming tasks in embedded systems, game development, and performance-critical applications.

1

Create the temperatures array

Create an integer array called temperatures with exactly these values: 30, 32, 31, 29, 28

DSA C

# Create the temperatures array with the given values
# Your code here

Hint

Use curly braces to list the values inside the array declaration.

2

Set the count variable

Create an integer variable called count and set it to 5, the number of elements in temperatures

DSA C

int temperatures[] = {30, 32, 31, 29, 28};
// Create the count variable and set it to 5
# Your code here

Hint

Count should be an integer variable equal to the number of elements in the array.

3

Delete the last element by reducing count

Write code to delete the last element by reducing count by 1

DSA C

int temperatures[] = {30, 32, 31, 29, 28};
int count = 5;
// Reduce count by 1 to delete the last element
# Your code here

Hint

Subtract 1 from count to remove the last element logically.

4

Print the remaining elements

Use a for loop with variable i from 0 to less than count to print the elements of temperatures separated by spaces

DSA C

int temperatures[] = {30, 32, 31, 29, 28};
int count = 5;
count = count - 1;
// Print the elements up to count
# Your code here

Hint

Use a for loop and printf to print each element followed by a space.
