• Functions are reusable blocks of code.
• add is the function name.
• int before the function name specifies the return type.
• (int a, int b) are parameters.
• return statement sends the result back to the caller.

// Define a function int add(int a, int b) { return a + b; // Adds two integers and returns the result }

void main() { int result = add(3, 4); // Call the function with arguments 3 and 4 print(result); // Output: 7 }
