Yeah, that sounds like a bit more than I want to tackle. I'll just give them different names. Thanks to both of you.

I've googled this and it looks to me like what I am trying to do is impossible. I'm trying to write a Displayfunction that can take different parameters and call the appropriate function based on...

OK, thanks. Will give it another shot.

What if the file is one huge line with a million names, no line breaks, and I only want the first, say, 10 names? Do I still have to either read a whole line or write my own getline that can accept...

I have a data file that, if I was using C++, I would use the getline function to read its data into the proper variables. However, the getline functions that C++ allows appear to not be available to...

All this program does is open mspaint with the Mickey Mouse picture.


int main()
{
system("mspaint c:\\mm.jpg");
return 0;
}

niek_e, Did you create the lonely_girl profile just so you could post your Mickey Mouse program and this response?

Regardless, +rep to both of you, if there are two of you, for making me laugh.

int main()
{
int i;
char a[32],*a1,b[64],*b1;
a1=&a[0];
b1=&b[0];

for (i = 0; i < 26; i++)
a[i] = i + 65;
a[26] = 0;

You still have to fix your initialization of the done[15] element, but the seg fault is gone since you've now set aside 16 elements. As far as the logic goes, it makes sense and it seems like it...

You can't use string in C. Also, we can't run the program since you haven't provided the GetLine and GetInteger and StringCompare functions.

Your done array has 15 elements and thus can handle indexes from 0 to 14. val has a potential range of 0 - 15. You have this on line 15:


if(!done[val])


which will be this if val is 15:
...

Well if you have the following equation:

f(x)=3x^2-5x

you need to extract the 3 and the -5. You need to know exactly what assumptions you can make regarding the user input (i.e. can you assume...

"It still doesn't work" isn't descriptive enough. It does work, to a point, but you are getting repeats. If x and y both flunk the primality test, n1 and n2 are unchanged and are printed again. ...

Lines 13 and 19. Make sure you have the larger number to the left of the % sign and the smaller number to the right of the % sign.

I'm not sure why you have a nested loop in this program. I don't think you need one. I think I would create a function that returns true or false (1 or 0) based on whether a number is prime. ...

Yes, but well deserved. The OP gave absolutely no indication at all (in either post) of what he was looking for. We are simply left to guess.

What kind of chip? Are you talking about microcontrollers? I use PIC microcontrollers, but there are a whole bunch of chip types and manufacturers and a whole bunch of C compilers. I would go to...

I question whether you want to #define this function instead of just declaring it at the top. Try replacing



#define GCD();


with this:

First, make sure you are using a C compiler if this is a C program and make sure the extension at the end of the file is .c, not .cpp. If this is a C++ program, you're in the wrong forum. Assuming...

Ah, OK, you are referring to these lines, perhaps?


x = ((-b - d)/(2.0*a));
y = ((-b + d)/(2.0*a));


I get a warning in C++ (not an error) which says "Warning: Converting from 'int' to...

You have that backwards. These lines:


#include <iostream>
using namespace std;


are fine with a C++ compiler, but cannot be used with a C compiler.

iostream isn't in C. I think you have quotes where you want <> in your #include for math.h, and you can't use "using namespace std" in C. Maybe you're not using a C compiler.

Definitely don't write 100 if statements. If you have a 2-D array of doubles, like, say:

where 100 is the number of groups, as in your case,...

I'm guessing you have a problem in line 4 when you declare your 2-dimensional array:

Do you have the implementation code for the functions in sort.h? It needs that file too in order to compile.

Does it compile on another compiler? Could be some specific option in Visual C++ that needs to be changed in the linker or whatever. Hard to say. Or it could be in the code itself. Posting the...

I don't think switch would be a good fit here. In order to use "switch" on a variable, the variable's type must be an ordinal type. You are comparing strings, and string is not an ordinal type, so...
