| | Is there a standard algorithm that can take the output of difftime (which is in seconds) and use it to print out the number of minutes, hours, days, weeks, etc.? I was going to try and calculate this myself by using the modulo, etc. but thought that something might pre-exist..  |
| | Here's what I went with. Note you want to do a break if you find out it's divisible as there is no point in checking all the numbers beyond it for divisibility.. [code] #include <iostream> using namespace std; void prime_num(int); int main() { cout << " Enter a number and …  |
| | [code] #include <iostream> #include <sstream> using namespace std; int main() { int a =23545; ostringstream o; o<<a; cout<<o.str().size()<<endl; return 0; } ./Temp 5 [/code] |
| | Basically, the only way to do this is what narue suggested and pass in the actual size as a parameter to the function. Either that, or use an STL collection, and use .size() |
| | Let me give you this hint - since several of the months have the same behavior - ie 1,3,5,7,8,10,12 are all 31 days, while 4,6,9,11 are all 30 days, then you could easily use a 'switch' statement on your month and not have to repeat all of that logic.  |
| | Hi Guys, So I'm trying to experiment with threads, though I'm running into some problems. Basically I'm trying to create multiple threads, where each thread is passed a different set of data. In my small example below, I'm starting off with a vector<string> of data. Each element of the vector … |

| | You are using time for purposes of generating the random number, but only once before the loop. You should probably reset the time each part of the loop. (void) time(&t1); (Though you may continue to have the same problem as I think time only holds seconds... ) Also, what you … |
| | I am trying to write a variable argument function on SUN solaris. According to MSDN, the _vscprintf function that I'm using on windows should work on unix as ANSI is listed. [b]_vscprintf[/b]<stdio.h>ANSI, Win 98, Win Me, Win NT, Win 2000, Win XP [size=2]However, including stdio.h doesn't seem to help. Is … |
| | I sometimes get a lot of traffic from certain ip's that are clearly trying to break in/snoop. Is there a way in IIS to block access for certain ip's? (or ranges?). I can do this in my ftp server software (non IIS)... |
| | If you want to make sure there are no numbers in a string, you can do a find_first_of( "01234567890"). If it equals anything other than string::npos, it's got a number in there.  |
 | I found this: [url="http://www.eskimo.com/~scs/C-faq/q2.13.html"]http://www.eskimo.com/~scs/C-faq/q2.13.html[/url] and this: [b]9.10: Why does sizeof report a larger size than I expect for a structure type, as if there was padding at the end?

| | Re: Run problems. Missing a semicolon here: unsigned long k //k as an unsigned long integer also, either change cout to std::cout or put a 'using namespace std;' at the top after the include. |

 | You must be using visual studio 6. You can disable the warning with a pragma statement. |
| | gebbit, you can also look into sprintf, which gives you a lot of options. |
| | This won't compile: k=n*[color=red]fact[/color](n-1); should be k=n*[color=red]facto[/color](n-1); After making that change, seems to work fine.. enter the number for which you want to find the factorial 7 the factorial of yhe number 7 is 5040 (Be careful though factorials get large very quickly and you have a risk of blowing … |
| | Hi, I'm trying to write some code that will validate if we are trying to write to nfs and if so, complain. From what I've read, the stat() call populates the st_dev with value of the file system type. On an nfs mount it tells me that it's '14'. I'd … |
| | Couple of problems: if (day = "m" || "M") must be if ( day == 'm' || day == 'M' ) because day is a single character. (Even if it were a string you couldn't do a comparison like that, you'd need to use strcmp) You must specify day once … |
| | Consider this working code: [icode] #include <iostream> using namespace std; class Base { public: void print(string val) { cout<<val<<endl; } virtual void print(int val) { char temp[1000]; sprintf( temp, "%d", val ); string tempstring = temp; print ( tempstring ); } }; int main() { Base a; string whatever= "BLAH"; … |
| | Hi, Trying to play with multithreading by taking some of my existing apps and converting them over. In doing so, I noticed a strange phenomenon that I've been able to reproduce in a very simple program. let's say I create 2 threads. Each thread simply does a for loop from … |
| | OK - so I installed windows 2003 server on my desktop, which is in the basement. I have a laptop upstairs (xp) which I want to connect to the desktop over remote desktop. This is working ok (networking, etc), except the way that 2003 server is working, it's making it … |

| | inside the if, you should be comparing $CHECKA and $CHECKB, not CHECKA and CHECKBKeep the space there. Also, try removing the ; and move 'then' to the next line. (not sure if this matters) |
| | Also, main really should return an int. |
| | Hi, If I have a JComboBox which has a list of Strings which can be selected, is there a way to insert a line/horizontal rule inside to indicate some sort of grouping of values? If so, how do I do it? (Also, the actual line ------ should not be selectable … |

| | So here's what I'm trying to do. Basically, I have a huge text file of strings which are delimited by a delimiter. I would like to read each string separately based on the delimiter. Note that each chunk can span several lines, so I don't want to read it line … |
| | Hi, I've inherited some code in C that acts as a server and receives requests over a socket. That is all working fine. I wanted to make a very small change to the server code to print out the hostname of the client connection. However, I'm always getting 0.0.0.0 as … |

| | So I'm trying to learn how to use function pointers (ie to pass the address of a function to another function to execute it - like a call back). I have it working when I use it as follows: Classes.h: [code] #include <iostream> using namespace std; class Class1 { public: …  |

| | I am trying to write a large file, but it always stops writing when it hits 2GB. (2147483647 bytes to be exact). I know it's not an O/S or disk issue (I'm on solaris) as I'm able to use the mkfile command to create a 3GB file. I'm using the … |
 | You're treating deck[i] like a pointer when it's not. |
| | You're gonna have to give us a bit more than that - how about some source code? |
| | Re: Urgent Help Why are you doing cout so many times inside the loop? You're going to get like 400 printouts... |
| | I'm probably missing some math aspect here, but couldn't you convert 4.33 to a string, find out what position the . is and have your answer? |
The End.
