Arrays & Strings

1What is C?✨

C is a powerful, low-level programming language that provides a strong foundation for understanding how computers work. It allows you to work closely with memory and system resources!

2Why Learn C?🎯

• ✓ Enhances your understanding of computer fundamentals
• ✓ Widely used in system programming and embedded systems
• ✓ Forms the basis for many other programming languages
• ✓ Great for performance-critical applications

3Your First Program💡

Let's write a simple program:
#include <stdio.h>
int main() {
    printf("Hello, World!\n");
    return 0;
}

This program tells C to display text on the screen.

4Working with Arrays🚀

An array is a collection of items stored at contiguous memory locations. Here's how to declare and use an array:
int numbers[5] = {1, 2, 3, 4, 5};
for(int i = 0; i < 5; i++) {
    printf("%d ", numbers[i]);
}

This code creates an array of integers and prints each number.

5Understanding Strings🔍

In C, strings are arrays of characters ending with a null character ('\0'). Here's an example of using strings:
char name[20] = "Alice";
printf("Hello, %s!\n", name);

This code creates a string and greets the user.

6Array and String Operations⭐

• You can perform various operations on arrays and strings:
• Access elements using indices
• Modify values at specific positions
• Use loops to iterate through elements
• Utilize library functions for string handling

7What You'll Build This Grade🧩

• ✓ Programs that manipulate data collections
• ✓ Simple games using arrays
• ✓ Text processing applications
• ✓ Interactive user interfaces with strings
