 | First, unwind that excessive indentation. 12 closing } in a row is just awful. This is how you should do an if / else if / else chain [code] if ( cond ) { } else if ( cond ) { } else if ( cond ) { } else …  |
| | > char filename[] = ""; This has no space to store an input - instant buffer overflow and broken program. Also, consider using fgets() to read each line, then deal with the line in memory. |
| | Have a go at working out an answer, and post your reasoning here. Then we can tell you if your approach is good. Simply telling you the answer won't help you understand why it is (now), or help you in a similar circumstance later. |

| | > x=(float**) malloc (T*sizeof(float*)); 1. Make sure you're compiling your code with a C compiler (not a C++ compiler). If you're getting warnings about "void* to T*", then you're compiling C++ code. 2. Remove the cast of the return result. It does nothing useful if this really is C code. … |

| | If you want to see what's happening, then do [ICODE]gcc -v -o hello hello.c[/ICODE] It will print out the full command lines generated for the compiler, assembler and linker. If you really wanted to, you could do the same things yourself. But doing so is highly specific to your current …  |
| | > I was looking for c++ specific i/o. But there is no *man* page for it like cin/cout. If it isn't cin/cout (or more generally, the C++ streams), then it's nothing to do with C++. For such information, you need to read the additional documentation which comes with your compiler …  |

| | Re: bad lag What exactly does port.read() do? Things I can think of include - it doesn't append a \0, so all your string functions are working on a prayer. - it doesn't do "framing", so if you happen to lose sync with the transmitter, you end up with messages like this > … |

| | > base64 algorithm which is used for the encryption of passwords No it isn't. Base64 is just about turning the unprintable into the printable. The data from any 3 random bytes is converted into 4 printable characters. Reversing this (back to 3 bytes) is easy. Then the real challenge begins. |

| | Read the documentation for your C compiler. The normal C convention is to pass all arguments on the stack. |
| | The cache works better when you HAVE loops, not when you don't. If all you've got is straight-line code, then the very fast processor is essentially bypassing the cache and it is stuck waiting for slow memory to deliver the next instruction. A populated cache on the other hand can … |

| | How does your program exit? One of the requirements for getting a gmon.out file is performing a "normal exit", which basically means dropping off the end of main() in the usual manner. If your program just drops dead, then you're not going to get a profile. Practice with some simple … |

| | > while(!feof(file)) This doesn't do what you think it does. feof() only becomes true when some file reading function (say fscanf has already FAILED). But since you don't check that, you potentially end up with some junk on the last record. Consider this an alternative [code] while( i < 100 … |

| | Well the cleanest thing to do would be to send a "quit" message from the client to the server. The server can then do an orderly shut-down. Instead of spraying machine-gun fire all over the system with your attempts to kill random processes. |
