Hello there, Please advise me what should I change with the statement to make sure that the new data will be write into the text file on the new line. im trying to put the value from a loop. Here is the code which only save the first data into the text file.

    int whitepix = countNonZero(frame_gray);"data.txt");
    outputfile << whitepix << endl;

Appreciate on your response

you probably need to show a bit more of the code.

(but i already guess: if"data.txt"); is inside the loop, you overwrite the same file again and again)

Hi Berak, thanks for the response.. yes :) it worked as what u had suggested. Move to the outer loop and the data is saved now!! Appreciate it.
