hey guys,

i'm currently making a virtual machine in c for a community project, no one else is willing to make one. i would have done it in C# which is my normal language, but part of the project said that it couldn't be reliant on any framwork or libraries. so we all decided that the virtual machine would be made in c and i was the person hat volunteered to make it.

so i got to work as quickly as possible learning how to program in c and then making my virtual machine. it's coming along nicely, except there's one major part of the virtual machine that i don't know how to do, how to read text from a file and then put it into an array.

so what i want to find out is how to read the contents of a file and then put it into an array. the array that i have to put the code in is called 'program'.

and when the contents is loaded into the array, is it possible to split it up at every newline or at every ' ' character? that would help a lot.

thanks for all your help,
Fletcher

I hardly can imagine anyone working at such a project like a virtual machine but unable to load a file. How you do it actually depends on the file format and on how you want to have some data in a file. At least show what did you try so far.

i am working on a virtual machine, don't doubt that. but at the moment, all of the parts code is already put into an array which is then run through the virtual machine. i don't know how to read from an outside file yet, and i thought that txt would be easiest and so i'll start with that and then move onto binary files and all that.

You read a file using the standard C library functions. As SA says it is hard to believe that you can write the code for a virtual machine and yet cannot do something as basic as reading a file into an array.

OP says "don't doubt". Okay, I don't doubt anymore. It actually depends on what one calls "working"... :-)

Maybe we will see a demonstration some time.

I could put up the source code if you wanted, but I'm still trying figure out how to read from a text file...

I don't think we really need to see this code to help you, not at this moment. But above, Richard just gave you a link to the MSDN help page where you have to start. What's the problem with it? Read it, write your code for reading the content you need, and ask some questions if you fave any problems with that.
