This is not “pure C” question, because C language standard doesn’t define how to access physical, linear or virtual memory at given address. In many or most environments, operating system won’t never let you directly access physical memory, or will only let you access physical memory if you ask it. For example on Linux with … Read more

Your task can be effectivelly accomplished using regular expressions. Your regex could look like: (?<=\[“)[^”]+ See it live here. The (?<=\[“) part is so called lookbehind, you say you are looking for anything that follows [“. Then you simply take any characters except ” Extract from .NET Regex Reference: (?<= subexpression) Zero-width positive lookbehind assertion. … Read more
Have you tried: std::string one = “stringa”; std::string two = “stringb”; std::string three = “stringa”; std::string four = “stringb”; if( one == three && two == four ) { return true; } else { return false; } 1 solved My loop condition isn’t being met
This is actually more complicated than it sounds. Most message boards don’t open up their API (usually to prevent spam), and if they do, you’ll probably have to work with them to get the details. The general idea is: Open socket to their server Send the appropriate data according to their API Profit If you … Read more
I think this may help you a little. the function scanf will read and ignore any whitespace characters encountered before the next non-whitespace character (whitespace characters include spaces, newline and tab characters — see isspace). A single whitespace in the format string validates any quantity of whitespace characters extracted from the stream (including none). Also … Read more
Well, the obvious choces are Strategy (one logger that can be configured to use different output options) and Composite (multiplex output over several output outions). So something like this (in Java): public class Logger { public interface LogOutput { void out(final String s); } // Composite – use to send logging to several destinations public … Read more

You don’t have to re-use the linked program(s), it’s just usually much faster than re-compiling/linking them each frame/drawcall. 3 solved Is it necessary to create couple program OpenGL? [closed]
getchar is still an int by the POSIX and C standards. Did you forget to include stdio.h or include something that redefines it? This example works for me: #include <stdio.h> int main() { int c; c = getchar(); } solved Console doesnt display histogram
