What's the difference between cout

There should be no difference at the user's end. The only difference should be an inward-facing artefact, a null terminator on the string "\n", that will not be printed and shown to the user. There could be some undefined behaviour in your code that manifested poorly in the earlier run, possibly as a result of the slightly different printing instruction, but there's not enough information here to say anything conclusive.
