If the parameters require a value, an equality sign mustĬonnect parameter and value. Keywords can be accompanied by parameters on the same line, separatedīy a comma.

The input deck basically consists of a set of keywords, followed byĭata required by the keyword on lines underneath the keyword. If any of the files it needs does not exist, an error message is generated and CalculiX will stop. STATE DYNAMICS step, CalculiX will look for a file with that name.

This section describes the input of CalculiX.

Add code to re-prompt the user for an input if the input was invalid. Compile, test, and verify your results.Ĥ. Add code to validate each user input, and print an error message if an input is invalid. Compile, test, and verify your results.ģ. break out of the loop early if the user enters the predetermined value. Add code to handle the sentinel value i.e. Compile, test, and verify your results.Ģ. Run a loop to read inputs from the user, store them in the array, the print out the array.

(See ' A Development Process' for a full example.) Compile and test often, each step of the way.ġ. Don't bang out the code all at once - break it down into steps and just do one step at a time. Step 4: Now that you have a step by step approach planned out, you can begin coding. Based on this, you can create a flow chart or pseudo-code for the logic of your program.

Write down, on paper, a step by step algorithm for how to accomplish your task. Step 3: Now that you have the basic requirements and a rough plan, you can start to design your logic (you still shouldn't be coding yet at this point). Therefore, you can probably make your sentinel value -1 (if the user enters this number, it signifies they are finished entering values). For instance, your array is called 'marks', so if we assume that you're reading grades, it's probably a safe bet that negative numbers are not to be expected. If the user enters an invalid value, you do not want that loop to continue until they enter a valid number, so it looks like you will need a validation loop within your main loop.Īlso note that trying to read for integers, and a character ('Q' or 'q') is, while possible, probably more difficult than you're ready to handle right now. You will need a loop that will keep asking for numbers until ten numbers have been entered, or the 'sentinel' value has been entered (indicating the user is done entering numbers).

You will need an array to store the input. The user can enter a specific (' sentinel') value to indicate they are finished.' If you do not have clear instructions yourself for what you're trying to accomplish, you will not be able to program a computer to perform that task. If the user does not enter a valid number, print an 'invalid' message and ask again. Based on what you've posted, I would say it's something along the lines of: 'Allow the user to enter up to ten numbers, and store them in an array. Step 1: Write down, in words, what your program needs to do. It should begin with a clarification of requirements and planning on how to achieve those requirements. Writing a program should not begin with code. You'll never get a decent program written that way. I can virtually guarantee that your 'if()' statement isn't doing what you think it is doing.īased on these observations, I feel it's a safe assumption that you're banging out code with little thought and wondering why it isn't working.

Secondly, you're trying to cram too much functionality into your code. These are basic errors that, while permissible to make in the course of writing code, should easily be detected and corrected before posting. You're missing a semi-colon after declaring 'quit' and you wrote 'scant' instead of 'scanf'. With respect to post #4, it's clear this was not done. It looks like you have several problems, mostly having to do with a lack of understanding of the language.įirst, you should be trying to compile and execute the code you write before posting it here.
