The computer screen glowed brighter than before.
The robot stood at the center of the display.

Below it, a message slowly appeared.
SYSTEM PROGRESS: 95%
FINAL MODULE DETECTED
FINAL CHALLENGE INITIATED
Pran leaned forward.
"So this is it."
The cursor blinked again.
_
Then the computer displayed another message.
YOU HAVE LEARNED THE CORE SYSTEMS
PRINTING
INPUT
CONDITIONS
LOOPS
FUNCTIONS
POINTERS
ARRAYS
Another line appeared.
NOW BUILD A COMPLETE PROGRAM
Pran smiled.
"This computer really turned learning programming into a game."
He thought about everything he had learned.
A real program needs several things:
• input from the user• some logic• loops to keep the program running• functions to organize code
Pran decided to build something simple but useful.
A number guessing game.
The computer would secretly choose a number.
The user would try to guess it.
The program would keep asking until the correct number was entered.
He began typing.
#include
int main() {
int secret = 7;
int guess = 0;
printf("Welcome to the guessing game!\n");
while(guess != secret) {
printf("Enter your guess: ");
scanf("%d", &guess);
if(guess == secret) {
printf("Correct! You win!\n");
}
else {
printf("Wrong guess. Try again.\n");
}
}
return 0;
}
Pran looked at the program.
"This actually uses a lot of things we learned."
Let's break it down.
First, the program creates two variables.
secret
guess
The secret number is 7.
The user must guess it.
Next, the program prints a welcome message.
Welcome to the guessing game!
Then comes the important part.
while(guess != secret)
This means:
Continue the game until the guess equals the secret number.
Inside the loop, the program asks the user for input.
scanf("%d", &guess);
Then it checks the answer using an if statement.
If the guess is correct:
Correct! You win!
Otherwise:
Wrong guess. Try again.
Pran ran the program.
The computer displayed:
Welcome to the guessing game!
Enter your guess:
Pran typed:
3
The computer responded.
Wrong guess. Try again.
The program asked again.
Enter your guess:
He typed:
5
Still wrong.
The computer responded.
Wrong guess. Try again.
Finally he typed:
7
The program printed:
Correct! You win!
Suddenly the entire screen flashed.
The robot jumped excitedly.

Then a system message appeared.
PROGRAM VERIFIED
Another message appeared.
ALL CORE SYSTEMS UNLOCKED
Pran leaned back in his chair.
"Did I just finish the system?"
The screen flickered again.
Then the computer printed one final message.
CONGRATULATIONS PROGRAMMER
Pran blinked.
"Programmer?"
Another line appeared.
YOU HAVE LEARNED THE FUNDAMENTALS OF C
Then another.
THIS WAS ONLY THE BEGINNING
The cursor blinked one last time.
_
Pran smiled.
He looked at the keyboard.
At the screen.
At the strange robot.
And he realized something important.
Programming wasn't about memorizing complicated code.
It was about thinking step by step.
Breaking problems into small pieces.
And teaching the computer how to solve them.
The robot waved.

Then the computer printed one last message.
END OF TRAINING MODULE
The screen slowly faded to black.
But before shutting down, a final message appeared.
NEXT STAGE AVAILABLE
ADVANCED PROGRAMS READY
Pran cracked his knuckles.
"Well," he said.
"Let's keep going."
Because this was only the beginning of his programming journey.
End of Book Part 1
The C Programming Adventure
You have now learned the core foundations of C programming:
• printing output• user input• variables• conditions• loops• functions• pointers• arrays
These concepts form the foundation of almost all programming languages.
But programming becomes even more powerful when we begin building real applications.
So in the next part, we will transition to building a completely different program — one that uses these concepts to create something more practical and interactive.
Your journey as a programmer has only just begun. 🚀
