It has to be compatible with the slot, but how does this have anything to do with software development?

>could someone please tell me what I need to use for this? Something besides char* because you obviously don't know what you're doing. I'd suggest using the string class, then you can use the c_str member function to get a pointer to const char for your hash function.

That's an interesting link that you've posted (for once).

>i am sry..i was in ahurry.. I think you're still in a hurry. Slow down, compose a coherent post with correct spelling and grammar, then you can use "in a hurry" in the past tense.

Not anybody, but I'm sure somebody does.

Your code shouldn't compile at all because you haven't terminated the structure definition with a semicolon. >date.d = atoi(str_date.substr(0,2).c_str()); >date.m = atoi(str_date.substr(2,3).c_str()); >date.y = atoi(str_date.substr(4,7).c_str()); substr doesn't use a begin/end pattern, it uses a begin/count pattern. The second argument should be 2, 2, and 4 for those three lines, respectively. …

>I want to know if that's a good idea, or what to look out for. If your goal is C++, there's little point in side tracking yourself with C. But do keep in mind that C and C++ require different mindsets. Good C isn't necessarily good C++, and vice versa. …

And?

If you get banned from this forum, you're not likely to last long on PFO. We're far less forgiving over there.

>My compiler says my code isnt standard c++? Your compiler is right. >#include <iostream.h> Some people will try to tell you iostream.h is deprecated, but they're wrong.

Check your spelling, check the number of arguments, check the type of arguments, and if none of that works, make a tiny program that exhibits the problem so that we can actually compile and link it ourselves instead of trying to decipher the snippets that you [i]think[/i] are relevant.

Or you can use stringstream and getline with ':' as the delimiter. That's generally easier to get right: [code=cplusplus] #include <iostream> #include <sstream> #include <string> int main() { std::stringstream in ( "A:B:C" ); std::string token; while ( std::getline ( in, token, ':' ) ) std::cout<<"Split token: "<< token <<'\n'; } …

You're storing the factorials in an array, but that doesn't change how you calculate the value. Do you know how to calculate a factorial?

Be more specific.

>Both methods throw an exception if you try to enter something other than an integer. How do you figure that? Only the second will actually throw an exception. The first will simply set cin to an error state (in which case the ignore will effectively be a no-op).

Let me get this straight. You went through four years of college with a focus on computer science and have [i]no idea[/i] how to build your projects on your own? I hope you didn't pay much for that course, and I'm rather afraid that you're about to enter the workforce …

>Do you have to have the studio or C++ express will do? The Visual C++ Express debugger is fully functional.

>This is a math problem. No, it's not. Reading the data as an integer strikes me as dangerous in this case.

It looks like the input specifies indices of which values are to be set to 1. Let's say you have an array of 10 rather than 100 (because I don't want to type that much). You initialize the array to 0's: [code] {0,0,0,0,0,0,0,0,0,0} [/code] Now let's say the user types …

In other words: [code=cplusplus] int …

So...have you tried [b]anything[/b] yet? If so, posting a little code would make you look like far less of a "gimme gimme" noob, and someone might actually help you.

If a number is divisible by 2, it's even. If it's not divisible by 2, it's odd. You can find out if a number is divisible by 2 by finding the remainder of division by 2. C++ has a remainder operator, %. So it stands to reason that if you …

There's plenty of software to control computers remotely, but if you want to do it by phone line, the computer has to be connected to one (which is quickly becoming a scarce occurrence). Most likely you're searching for the wrong thing (because your search strings are incorrect), or you're searching …

>For example if i convert 255 from base 10 to base 2 >i am getting 11111110 instead of 11111111. That particular example works fine for me. Though your code has some...interesting aspects.

>I'm using the stack twice and I didn't find it efficient. Are you just eyeballing it and thinking "that can't be efficient", or did you profile multiple executions and get hard numbers that proved it's consistently slower than your allowable limit?

>it wont compile and I dont understand the error message And we're supposed to divine what that error message is? Maybe you should post it.

>out<<num.a; >out<<num.b; First I'd suggest you separate those two values with something. Your actual output is 43,0. [code=cplusplus] if(i==1) { num.a = line[i]; } [/code] At position 1 in "7+i3" is '+'. So the first problem is that you're assigning the wrong character. The second problem is that you're assigning …

>can anyone please tell me how? Use stringstream to handle the conversion for you.
