Example Detailed Explanation:
This program demonstrates how to optimize power consumption in an IoT project by using efficient coding practices.
The program starts by generating a random range of numbers using the `generateRandomNumber` function. This range will be used to calculate the sum of all prime numbers in the range.
Next, the program calls the `sumOfPrimes` function to calculate the sum of prime numbers in the generated range. This function iterates over each number in the range and checks if it is prime using the `isPrime` function. If a number is prime, it is added to the sum.
After calculating the sum, the program writes the result to a file named ‘output.txt’ using the `ofstream` class. If the file is successfully opened, the program writes the result to the file and then closes it. If there is an error opening the file, the program displays an error message.
Finally, the program terminates and returns 0.
