Sample Program Code – C++ for Embedded Systems
#include
#include
#include
// Function to calculate the sum of all elements in a vector
template
T sum(const std::vector& vec)
{
T result = 0;
for (const auto& element : vec)
{
result += element;
}
return result;
}
// Function to calculate the average of all elements in a vector
template
T average(const std::vector& vec)
{
T total = sum(vec);
return total / vec.size();
}
// Function to find the maximum element in a vector
template
T max(const std::vector& vec)
{
T result = *std::max_element(vec.begin(), vec.end());
return result;
}
int main()
{
std::vector numbers = { 5, 2, 8, 3, 9, 1 };
int total = sum(numbers);
std::cout << 'Total: ' << total << std::endl;
int avg = average(numbers);
std::cout << 'Average: ' << avg << std::endl;
int maximum = max(numbers);
std::cout << 'Maximum: ' << maximum << std::endl;
return 0;
}
Example Output:
Total: 28
Average: 4
Maximum: 9
Example Detailed Explanation:
This program demonstrates the use of embedded C++ algorithms to achieve high performance in calculations involving vectors.
The program defines three template functions: sum, average, and max.
The sum function calculates the sum of all elements in a vector by iterating through the vector and adding each element to a result variable.
The average function uses the sum function to calculate the total sum of all elements in the vector, then divides that sum by the size of the vector to get the average.
The max function uses the std::max_element algorithm from the C++ standard library to find the maximum element in the vector.
In the main function, a vector of integers is created and initialized with some sample values.
The sum, average, and maximum of the vector are then calculated using the respective functions and displayed on the console.
The program showcases best practices in pursuit of high performance through embedded C++ algorithms by utilizing generic programming techniques and leveraging pre-existing algorithms from the C++ standard library.
