 | atoi is a C function expecting a char* Perhaps you need to implement a small conversion function which accepts a std::string instead. |
| | Now why are you casting the result of malloc? Could it be that you didn't include stdlib.h and thus the compiler considers malloc as returning an int rather than a pointer? This can be a well hidden and very obscure bug. > I need an array of approx. 2,00,000 elements.But …  |

| | Well how do you run a single test case at the moment? How do you run several test cases? Is it typing in a somewhat repetitive command? Post some examples. |

| | Re: Parsing a string If you don't know how many strings, then use a std::vector<std::string> instead of named variables. Something like [code] vector<string> fields; string temp; while ( getline(isstream,temp,'|') { fields.push_back(temp); } [/code] Then check fields[0] for whatever. |

| | And so it begins..... If someone isn't smart enough to think of a project to do, offering them a project title doesn't do anybody any good. First they can't think of a title, so you suggest one. Then they can't figure out what that means, so they ask you to … |
| | > hi i want to compile .c file as .cpp file using makefile!!. You'd better read [URL="http://david.tribble.com/text/cdiffs.htm"]Incompatibilities Between ISO C and ISO C++[/URL] then.

| | It goes up when you call testmap(), but does it go up again when you call testvec() ? Using a process monitor to determine how much memory is in use can be misleading. When you delete memory in your program, it typically goes back into a pool of memory owned … |
| | Given the number of spammers (and other 1-posting drive-by's), how about designating certain threads as "fly paper". Fly paper threads have a high post count, and lots of buzz words, but are essentially useless to anyone who actually bothers to read them. If someone actually posts on them, they basically … |
