Well, the pesudo code should be converted to a code and then try with some test input.
Well, YES, you cant just compile a pesudo code. So on what language are you suppose to implement the pesudo code. There are few tools which converts the pesudo code to code. But, you will have to learn the pesudo code standard and which that specific tools can understand.
Some hint on the looks like Yacc, Yapp. Wel those tools are used for compiler design but you cant use it for your application. They understand a notation called BNF.
That should give an idea. YOU WILL HAVE TO IMPLEMENT THE CODE TO TEST IT.
I don't agree with the fact that you have to implement it. As the assignements states: write test plans and dry runs. That means that you'll have to identify where the code could break, what critical points are, are there range issues, what values are needed by variables to fall through an if/case/while/for (or not).
>Well from wot i no pseudocode isnt real code so how can i test it?
The same way you test real code without running it: trace the execution with paper and pencil using a small amount of sample data. Not only does this give you a better idea of what your code is doing, regular paper tests help you to think like a compiler when you're actually writing code.
"Desk checks" - there's a term you don't hear enough anymore. And to get students to do such - unheard of!
Narue's comments are spot on. If students (and real life programmers, as well) would spend more time checking, tracing, double checking their logic before ever touching the keyboard, so much anguish and time would be saved in the long run.
