I am stuck on a logic problem.
I have the following struct:
struct MeasurementData
{
bool complete = false;
std::bitset<3> mode;
std::bitset<12> frame_counter;
std::bitset<16> expo_time;
std::bitset<16> expo_time_max;
std::bitset<24> ntc_val0_ref_2_4V;
std::bitset<24> ntc_val0_ref_2_1V;
std::bitset<24> ntc_val0_temp_2_4V;
std::bitset<24> ntc_val0_temp_2_1V;
};
struct MeasurementData
{
bool complete = false;
std::bitset<3> mode;
std::bitset<12> frame_counter;
std::bitset<16> expo_time;
std::bitset<16> expo_time_max;
std::bitset<24> ntc_val0_ref_2_4V;
std::bitset<24> ntc_val0_ref_2_1V;
std::bitset<24> ntc_val0_temp_2_4V;
std::bitset<24> ntc_val0_temp_2_1V;
};
To copy to clipboard, switch view to plain text mode
Where the field frame_counter is a progressive number incremented after each measurement (starting from value 0).
To fill in the fields of the structure I analyze an input file where each row contains the values that I have to insert in the structure.
So I create a vector of structures and I create a new struct each time I parse a new row
std::vector<MeasurementData> frames;
std::string line;
while (std::getline(input, line))
{
processLine(line, frames); // <- Here I create a new struct instance and add it to the vector
}
input.close();
std::vector<MeasurementData> frames;
std::string line;
while (std::getline(input, line))
{
processLine(line, frames); // <- Here I create a new struct instance and add it to the vector
}
input.close();

My need is to find the missing frame_counter values when processing the corresponding file line
For example:
In my file I have 48 rows, this implies the creation of 48 struct instances and the frame_counter should start at 0 and end at 47 but in my case I have 3 missing measurement
frame_counter = 0 is missing
frame_counter = 9 is missing
frame_counter = 12 is missing
I determine it by postprocessing the vector of structs. Is not what I want, I would determine it at the "file line processing" time but I can not find a good logic that solves my problem.
Below is how I do it now:
std::vector<MeasurementData> frames;
std::vector<int> counters;
for (const auto& frame : frames) // frames is my structs vector
{
int counter = (int)(frame.frame_counter.to_ulong());
counters.push_back(counter);
}
// And search for missing frames (assuming vector is ordered)
for (int i = 0; i < counters.size(); i++)
{
if (!std::binary_search(counters.begin(), counters.end(), i))
{
std::cout << "Frame " << i << " is missing" << std::endl;
}
}
std::vector<MeasurementData> frames;
std::vector<int> counters;
for (const auto& frame : frames) // frames is my structs vector
{
int counter = (int)(frame.frame_counter.to_ulong());
counters.push_back(counter);
}
// And search for missing frames (assuming vector is ordered)
for (int i = 0; i < counters.size(); i++)
{
if (!std::binary_search(counters.begin(), counters.end(), i))
{
std::cout << "Frame " << i << " is missing" << std::endl;
}
}
