    Explanation needed, what is this?

    Ok I made a very small program that takes two numbers, subtracts one from the other and well you get it. Anyways I was going through My documents trying to find the different files for them(some idiot moved them but that is besides the point)and I opened up one file that I thought was connected and my computer didn't know what to use so I told it to try using my compiler and this is a short example of what it gave me, what is this?

    Code:
    001100 FF FF FF FF FF FF FF FF   FF FF FF FF FF FF FF FF
    001110 FF FF FF FF FF FF FF FF   FF FF FF FF FF FF FF FF
    001120 FF FF FF FF FF FF FF FF   FF FF FF FF FF FF FF FF
    001130 FF FF FF FF FF FF FF FF   FF FF FF FF FF FF FF FF
    001140 FF FF FF FF FF FF FF FF   FF FF FF FF FF FF FF FF
    Please keep in mind that this is a VERY short example of what was displayed, it goes on for quite a while(I can't copy and paste the numbers and I don't want to type them all out, as it is copying and pasting the groups of F's shows them as y's with two dots over their heads so whatever) so if anyone cares to tell me what is going on I would appreciate it, also just tell me if you need more info and I will try if I have more time.

    how can you programming on not know what this is?
    My guess is that you opened a data file of some sort, all this is, is hexadecimal, every program, character, whatever is made up of 1's and 0's, 256 is the highest single number (8 1's or 0's) instead of viewing a programing that just looks like numbers, letters, symbols, etc you can view it as numbers (1's and 0's) or decimal, or hexadecimal, FF = 255. You probably just opended up a .exe file or something like that, dont worry about it, it isnt your source code, however it might be your compiled program.

    I am not programming yet, I am just learning so this is like a test and I don't know all of the background stuff either but I am learning, I just wanted to know.

    Do you have some code that goes along with this?

    Well CAP I think that file (or something) produce a hex dump.

    The code isn't important(although I will post it) but all I wanted to know was what exactly this file was as it is related to the rest of the program I couldn't just not know(I am narrotic that way, lol).

    Code:
    #include <stdio.h>
    
    void calculator(void)
    {
    	float value1;
    	float value2;
    	float total;
    
    	printf("\nPlease enter your first number: ");
    	scanf("%f", &value1);
    	
    	printf("\nPlease enter your second number: ");
    	scanf("%f", &value2);
    	total = value1 * value2;
    
    	printf("\nThe total of adding both of your numbers together is: %f\n\n", total);
    
    }
    
    main ()
    {
    	calculator();
    	return 0;
    }
    I completly realize that this can be fixed(like not putting all of "calculators" code in the beginning)but this was just to mess around with after Shadow posted a fixed version of my other attempt so I thought I would try again.

    There might be a way or two to do what you're doing better, because I haven't really looked at the code close enough. Keep on trying though. Have any other questions, be sure to ask them!

    I am sure I will have more questions soon enough but for now I have experimented enough so I can go back to reading my book(which I left like a week ago to do stuff on my own and damn does that method work )
