delete lines in the file

delete lines in the file

I am using a file as Input in program...The file contains round about 1,00,000 lines .My program after each iteration takes a data from that file at process it. My Question is when a particular data is used once it will not be used any further .In one word i want to skip that data in the subsequent iteration... My solution was to copy the data that was not used is copied in another temporary file and that file is renamed to the original file .Here the time complexity increases rapidly and I want to avoid it.. Thanks for the reply in advance!!!!
