What you will build and learn
You will build a grade calculator that stores a score, decides pass or fail, and prints a clear result. Keep the decision separate from printing so each part stays easy to change.
- Include stdio.h
- Declare an int score
- Use if/else for the pass decision
- Print with printf
Step 1: Create the program skeleton
Every beginner C program needs includes and a main function. main is where execution begins when you press Run.
#include <stdio.h>
int main(void) {
int score = 72;
if (score >= 40) {
printf("Pass\n");
} else {
printf("Try again\n");
}
return 0;
}Output
Pass
Project extensions
Add a second condition for distinction, or read the score with scanf. Keep changes small and re-run after each edit.
- Print Distinction when score >= 75
- Read score with scanf
- Add a second subject average
Frequently asked questions
Do I need an IDE for this tutorial?
No. A simple editor and a C compiler are enough. Avora Learn also lets you practice visually.
Why return 0?
Returning 0 from main traditionally signals successful program completion.
