    Help please

    Hi, have the below mention design, anyone know how to write the program or can direct me to any help? Any help will be greatly appreciated, thanks. Take for example an input string "This is *swaped* here no change" will produce an output string " This is *depaws* here no change".

    initialise variables to be used
    read in string to be tested
    loop while end of the string is reached
    if swap is off then
    copy characters from input string to output string
    if end
    if asterisk is found then
    determine the start and stop position of swap
    set swap on
    if end
    if swap is on then
    execute the swap
    set swap off if swap completed
    if end
    loopend
    write out the input string
    write out the output string

    Step 1 - write a program which reads input, and prints the input back to the user unchanged.
    Step 2 - add code to print a message whenever a '*' is seen
    Step 3 - print the number of characters counted between two adjacent '*'

    That should get you going.

    If at first you don't succeed, try writing your phone number on the exam paper.

    Have you ever written a C program before?

    Surely your teacher has gone over input and output, even if it's using gets(). At least show what you know along those guidelines I posted so we can best help you with the bit you're actually stuck on.

    The board rules/guidlines state we aren't going to do the work for you. If you don't know how to do the assingment, I would suggest talking to your teacher, because if your in a programming class and aren't learning HOW, to program, I think their might be a problem.
    If any part of my post is incorrect, please correct me.

    But you've done the printf("hello world\n"); program right?

    And perhaps extended it to printf("hello %s\n", name );

    Ill covert it to C++ to see if he has used it then
    something like
    Code:
    cout << "Hello World\n";
    cout << "Hello World" << endl;
    std::cout << "Hello World" << std::endl;
    std::cout << "Hello" << " World" << std::endl;
    any of those can do Hello World, so I want to cover all the bases. Their are more, but those are basic ones I would say.
