| | Hi, I was reading something that said goto was bad. Why is it a bad practice to use it?  |
| | Hi, I'm reading a bitmap manually to try and make a program that does steganography, but I can't read the file correctly. The headers I read come out completely messed up, and they fail the check to see if I'm reading a bitmap file or not (if (FileHeader.bfType != (int)"BM")). … |
| | I have tried to do this before. Just read a tutorial on how to do it by hand and make a function or whatever. Check this out: [url]http://www.permadi.com/tutorial/numBinToDec/index.html[/url] Pretty much, you move left starting from the first binary digit on the right. You increment the power from 0, and multiply …  |

| | Hi, I'm need to be able to load bitmaps, preferably as resources, draw them, and get their size. How would I do this? I'm on Windows, and using Dev-C++ 4.9.9.2. |

 | if you are getting multiple definition errors, change your headers to look like this: [Code=C++] #ifndef HEADERNAME_H #define HEADERNAME_H // Your code here #endif [/Code] That way if you include a header more than once, it'll only be included if it hasn't been. |

 | You can do that: [code=C++] #include <sstream> std::string Convert (float number){ std::ostringstream buff; buff<<number; return buff.str(); } [/Code] but for more precision, include <iomanip>, and add setprecision(<number of digits of precision>) in your buff<<number. Like "buff << setprecision(32) << number;" |
| | Re: Big numbers Use the GMP library. It works for me. If you're using Dev-C++, you can just search for packages online with the built in "Check for updates/packages" thing, and find it in the list. If not go here: [url]http://gmplib.org/[/url] |
