i need write file parser in c++. here's code : std::string line; vector<string> slice; while(getline(m_inputstream, line)) { } my file big, loop takes 12 seconds. my c# code : streamreader sr = new streamreader(filename); string strline = ""; while (!sr.endofstream) { strline = sr.readline(); } and takes 0.6 seconds... doing wrong in c++? firstly, doing slice ? chances c# version reading string discarding - , c# jit optimising no-op, 0.6 seconds takes initialise , quit. c++ version generate code read string processing input file. make sure c++ 1 built release settings if you're going compare performance, debug code meaningless perf. do string , you'll see different performance figures, , check memory usage in both systems, c# 1 use lot more ram until gc kicks in.

today have learned 2 things 1 - displaying int format : 0001 in text box number.tostring("0000."); 2 - displaying double format : £ 03.00 in text box price.tostring("£ 00.00"); my questions is: how display limitation of string in c#? i mean value in string is string mystring = "hello world!" i display 20 letters display "hello world! " and if more 20 letters skip displaying rest example: string mystring = "i love every thing :*" it display following: "i love every thing y" 20 letters maximum display (counting spaces).. any idea? you need use substring or padright int length = 20; string original = "i love every thing :*"; string finalstring = original.length > length ? original.substring(0, length) : original.padright(length); this take appropriate length substring, or pad spaces, needed.

i confused inheritance in .net , here why. i of understanding structure cannot inherit class in .net, example, following won't compile: struct mystruct : myclass { } but today read integers (and other value types) structs , not objects , inherit valuetype class. valuetype class inherits system.object , purpose override methods in system.object make these methods suitable value types. so what's deal? can structure inherit class in .net, can not or can in circumstances? thanks within guts of .net, definition struct containing members same definition class same fields , members, , inherits system.valuetype . note compilers not allow 1 declare class inherits valuetype , when 1 declares struct , compiler, "behind scenes" declares class does. what makes value types special in .net way run-time allocates storage locations (variables, fields, parameters, etc.) when storage location of type not inheriting valuetype declared, runtime allocate sp...

can write pure c++ app android? (for example, using ndk?) considering there's no difference of functionality, pure android c++ app faster , consumes lesser memory android java app? in guess, guess yes because c++ app won't garbage collection causes frame rate hiccup. yes , yes, althrough google says: "using native code not result in automatic performance increase, increases application complexity... if write native code, applications still packaged .apk file , still run inside of virtual machine on device. fundamental android application model not change." from http://developer.android.com/sdk/ndk/index.html (personally, don't agree writing in c++ automatically makes more complex program java, i'd it's other way around skilled c++ programmer)
