c - read an unknown number of lines - i need implement in c programme ,which reads unknown number of lines stdin. know maximum number of lines 100. tried utilize gets ,but don`t know when stop loop. can advise me how implement it? this depends on when want programme stop. there several mutual approaches: never: run infinite loop until end-user hits ^c or otherwise terminates programme using facilities of operating system until user enters special marker, i.e. "keyword" quit , exit , etc. on line itself until user enters empty line (i.e. hits enter ) since max number in case 100, can utilize limit automatically terminate input 1 time max reached. c input stdin gets

c++ - Strange behaviour updating sprite position - i'm coding simple roguelike game in c++ using sdl library, , have problems moving character on screen. each time frame needs rendered, update position of sprite using update() function, nil if player standing still. issue motion command, , starting animation, utilize step() function called 1 time per each player motion 1 tile another. upon receiving "up" command, game behaves fine , character moves smoothly in 1 sec new position. however, when "down" command given, moves @ half speed, , after 1 sec has passed, instantly "teleported" final position, sudden flicker. code motion identical, fact in 1 case delta motion summed y position, in other case subtracted. maybe fact position integer , delta double causing problems? sum , subract behave differently (maybe different rounding)? here relevant code (sorry length): void player::step(player::direction dir) { if(m_status != standing) //...

.net - Validating xml signature on part of the document using SignedXml - i using signedxml class validate signature in xml document. signature refers part document. i able verify signature, how can sure signature signing specific part of document need validate? sign different part of document using same key , signature still valid. from understand, signedxml automatically verifies signature against part of document that's supposedly signed. a digital signature verified passing signature value and data/content that's supposedly signed (or hash value of it). means if signature verifies, can sure right part of document signed. if signs different part of document , you're verifying signature against non-signed part of document, won't positive result. , due construction of xml, signedxml verifies signature against what's suppposedly signed, not against else. .net xml xml-signature xml-dsig
