Continue loop(for) at position break(Vector C++)

by

I have a code:

uint8_t x = 0;
typedef std::vector<Data> Data_Record;
const Data_Record& getData() const;
main()
{
    while(1)
    {
        get1();
        get2();
    }
}
void get1()
{
    for (const auto& dataRecord : file.getData())
    {
        if( x==10)
        {
           break;
        }
        x++;
    }
}

You see dataRecord read at position 10. How to continue get1() with next dataRecord (postion 11). Please help me. Thank you so much!

  • You have to rewrite your code, coroutine or handle that yourself (with a class?).

    Use and old-style for loop with an iterator. Remember the iterator when breaking, and then use it as a starting point of the next loop.

    What should happens when all elements have been processed? restart, end the main loop?

  • @Jarod42 it is only send data and continue to read data

    – 

  • You cannot do it in the get1(). You have to make changes in getData() or better to write an overload of getData() which returns from where it left last.

Instead of using a while loop, you can try using a for loop.

uint8_t x = 0;
size_t currentPosition = 0;

void get1()
{
    const auto& data = file.getData();
    
    for (size_t i = currentPosition; i < data.size(); ++i)
    {
        const auto& dataRecord = data[i];
        
        if (x == 10)
        {
            x = 0;
            currentPosition = i + 1;
            return;
        }
        
        x++;
    }
}
