    Incrementing a Dollar amount

    All,
    I am new programmer to C. Can anyone help me.
    Here is my question :
    I have a dollar amount of $23444.65
    Now I have to put this dollar amount into a variable and when ever I run my script the variable should be incremented by 1.
    Example : If my variable is $23444.65 on first run output should be $23445.65
    on next run output should be $23446.65 and next run output should be $23447.65.

    Can anyone help me to write a simple function for this in C coding.
    and where can I test this code.(like any free C Compilers).
    As I am new to C programming I dont know any basics of C.

    You should probably get a book, then.
    A variable to store that must be a float or double.
    Incrementing is done easily via var++.

    Free IDEs:

    Google for it, and you'll find them. IDE's come with a compiler, of course.

    Microsoft's free version of Visual C is a popular choice.

    Check the link. IDEs do usually come with compilers.
    Visual Studio is a set up & go with all you need, but it's for Windows. I can't say what OS you have.

    You could also try Dev-C++, if you're on Windows.

    If you're on Linux, you likely already have gcc, a command-line C compiler. Search for some gcc tutorials. For a Mac, you could try installing Xcode.

    I'd be willing to bet that the OP is using Windows, though.
