Resolve Driver Collision

Question

Problem: Resolve Driver Collision. Solve this hands-on electronics task on EWskills.

Accepted Answer

#include 
using namespace std;

// Motor driver A
namespace DriverA {
    void init() {
        cout << "A INIT";
    }
}

// Motor driver B
namespace DriverB {
    void init() {
        cout << "B INIT";
    }
}

int main() {
    int x;
    cin >> x;

    if (x == 1) {
        DriverA::init();   // call driver A
    }
    else if (x == 2) {
        DriverB::init();   // call driver B
    }

    return 0;
}

Explanation & Logic Summary:

Both drivers expose a function named init()
Namespaces prevent symbol collisions between modules
DriverA::init() and DriverB::init() explicitly select the correct driver
This demonstrates the core purpose of namespaces in Embedded C++

Firmware Relevance & Real-World Context:

Embedded projects often include:

vendor HALs
multiple driver implementations
protocol stacks
RTOS layers
duplicated function names (init, start, read, etc.)

Namespaces prevent conflicts when integrating multiple codebases.
This is especially important in large embedded systems or when mixing vendor SDKs with custom drivers.
