Solution: Sensor Calibration System

Explore how to implement a sensor calibration system in C++ by using references to modify variables directly and pointers for safe memory access. Understand the importance of validating pointers and efficient data handling to write reliable and maintainable code.

We'll cover the following...
C++
#include <iostream>
// Function to modify the original variable using a reference
void calibrateSensor(double& temp, double offset) {
    temp += offset;
}
// Function to read the variable using a pointer (read-only)
void readSensor(const double* tempPtr) {
    if (tempPtr != nullptr) {
        std::cout << "Calibrated Temperature: " << *tempPtr << "\n";
    }
}
int main() {
    double currentTemp = 25.5;
    double calibrationOffset = 2.0;
    std::cout << "Original Temperature: " << currentTemp << "\n";
    // Pass by reference happens automatically based on the function signature
    calibrateSensor(currentTemp, calibrationOffset);
    // Pass the address of the variable to the pointer parameter
    readSensor(&currentTemp);
    return 0;
}
