    Printf discussion

    Hi gentlemen ;
    I have last confused question about C programing function which is printf()
    Lets assume I have assigned to printf a string like "Hello World" ; so the Pc save that world into specific address as Data; my question Once the pc wants to read "Hello World" from specific address; is he reading it char by char sequential or in parallel? In other words once "Hello World" printed on my screen; is it printed on my screen one by one sequential or in parallel? which at the end all chars are printed ..

    i believe that both input from the keyboard and output to the screen is loaded into a buffer then dealt with as an entity but its a while since i read about that i moved onto such exciting things as if statements and for loops

    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
