What is C - Hands-On Activity

What is C

📖 Scenario: You want to learn the basics of the C programming language by writing a simple program that prints a message.

🎯 Goal: Create a simple C program that prints the message "Hello, C!" to the screen.

📋 What You'll Learn

Create a C program with a main function

Use printf to display text

Include the stdio.h header for input/output functions

End the program with return 0; to indicate successful completion

💡 Why This Matters

🌍 Real World

C is used to write programs that control hardware, build operating systems, and create fast applications.

💼 Career

Knowing C helps you understand how computers work and is useful for jobs in embedded systems, game development, and system programming.

1

Create the basic C program structure

Write the first two lines of a C program: include the stdio.h header and start the main function with int main().

C

# Include the standard input/output header and start the main function
// Your code here

Need a hint?

Remember to include stdio.h to use printf.

2

Add a print statement

Inside the main function, write a line using printf to display the text "Hello, C!\n".

C

#include 

int main() {
    // Your code here

Need a hint?

Use printf with the exact text including the newline character \n.

3

End the main function

Add the line return 0; to indicate the program ended successfully, and close the main function with a closing brace }.

C

#include 

int main() {
    printf("Hello, C!\n");
    // Your code here

Need a hint?

Make sure to close the main function with }.

4

Run and display the output

Write a comment or print statement to show the program output is Hello, C! on the screen.

C

#include 

int main() {
    printf("Hello, C!\n");
    return 0;
}

// Your code here

Need a hint?

When you run the program, it should print exactly Hello, C!.
