Write a C++ program defining a `Circle` class with radius, computing its area and circumference (use PI = 3.14159).
A single floating-point number representing radius.
Print area and circumference.
Radius > 0
7.0
Area: 153.94, Circumference: 43.98
Uses mathematical constants inside object methods.
#include <iostream>
#include <iomanip>
class Circle {
public:
double radius;
void compute() {
// Write your code here
}
};
int main() {
Circle c;
if (std::cin >> c.radius) {
c.compute();
}
return 0;
}Embedded systems rely on efficient low-level programming to interact directly with hardware. In this course, you will learn how to write practical Embedded C programs used in real microcontroller-based systems. Rather than focusing only on theory, this course follows a practice-driven approach. Each lesson includes hands-on coding exercises that simulate real firmware development tasks used
