Write a C++ program that reads an integer and counts the total number of digits it contains.
A single integer N.
Print the total number of digits.
-1000000000 <= N <= 1000000000
4521
4
Divides the number by 10 in a loop until it becomes 0 to count digits.
#include <iostream>
int main() {
long long n;
if (std::cin >> n) {
// Write your code here
}
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
