Simple Namespace with Variables

Question

Problem: Simple Namespace with Variables. Solve this hands-on electronics task on EWskills.

Accepted Answer

#include 
using namespace std;

namespace Config {
    int baudRate = 9600;
    int threshold = 50;
}

int main() {
    cout << "Baud: " << Config::baudRate 
         << ", Threshold: " << Config::threshold;
    return 0;
}

Explanation & Logic Summary:

The namespace Config is predefined.
The user simply declares two variables inside it.
In main(), the variables are accessed as Config::baudRate and Config::threshold.

Layman’s Terms

Think of Config like a settings folder. You put baudRate and threshold inside, and the program fetches them from there.

Firmware Relevance & Real-World Context:

This mirrors how embedded firmware often groups constants and configuration values in namespaces for organization and type safety.
