Write a C++ program that declares an integer variable, assigns a value, uses a pointer to store its memory address, and prints the value by dereferencing the pointer.
A single integer N.
Print the value accessed via the pointer.
-100000 <= N <= 100000

Pointers store memory addresses of variables and allow indirect access using the dereference operator (*).
#include <iostream>
int main() {
int n;
if (std::cin >> n) {
int *ptr = &n;
// Write your code here to print value via ptr
}
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
