Introduction
Programming languages power the digital
world, but have you ever thought about creating your own? In this blog, we’ll
explore how to build a basic programming
language interpreter in C. This beginner-friendly project helps students
(aged 8-16 years) learn C
programming fundamentals, file handling, and program execution.
🛠Project Overview
This
project involves:
✅ Reading a script file (script.txt) containing simple commands.
✅ Processing variable assignments and print statements.
✅ Storing variables and retrieving
values.
✅ Handling syntax errors gracefully.
🔹 Example Script File (script.txt):
x = 100;
y = 50;
print x;
print y;
🔹 Expected Output:
x = 100
y = 50
🚀 Features &
Enhancements
🔹 File Handling: Reads and executes commands from an external file.
🔹 Variable Storage: Saves values in memory for later retrieval.
🔹 Error Handling: Detects undefined variables & syntax mistakes.
🔹 Scalability: Can be extended with arithmetic operations, loops, and conditionals.
📜 C Code
Implementation
The program reads commands from script.txt and executes them. Here’s a glimpse
of the code:
void executeLine(char *line) {
if
(sscanf(line, "print %s", arg1) == 1) {
int index = getVariableIndex(arg1);
if (index != -1) printf("%s = %d\\n", arg1,
variables[index].value);
else printf("Error: Undefined variable %s\\n", arg1);
}
else if (sscanf(line, "%s = %d", arg1, &value) == 2) {
setVariable(arg1, value);
}
else {
printf("Syntax Error: %s\\n", line);
}
}

📌 How to Use in
Code::Blocks IDE
1️⃣ Create a new C file → Paste the C code.
2️⃣ Create script.txt → Add example commands.
3️⃣ Compile & Run → Type the script filename (script.txt).
4️⃣ View Output in the terminal.
✅
You’re now running
your own programming language! 🎉
📣 Final Thoughts
Building a simple interpreter in C is a fun and rewarding way to learn
programming concepts. Try expanding
it with math operations, loops, and user-defined functions.
