file - C++ return string keeps getting junk -

-

why return string here have sorts of junk on it?

string getchunk(ifstream &in){ char buffer[5]; for(int x = 0; x < 5; x++){     buffer[x] = in.get();     cout << x << " " << buffer[x] << endl; } cout << buffer << endl; return buffer; }  ifstream openfile; openfile.open ("bacon.txt"); chunk = getchunk(openfile); cout << chunk;

i load of junk in string has junk on end of it, though debug says buffer being filled correct characters.

thanks, c++ lot harder java.

you need null terminate buffer. make buffer size 6 characters , 0 initialize it. fill first 5 locations you're doing now, leave last 1 alone.

char buffer[6] = {0};  // <-- 0 initializes array for(int x = 0; x < 5; x++){     buffer[x] = in.get();     cout << x << " " << buffer[x] << endl; } cout << buffer << endl; return buffer;

alternately, leave array size same, use string constructor takes char * , number of characters read source string. 

char buffer[5]; for(int x = 0; x < 5; x++){     buffer[x] = in.get();     cout << x << " " << buffer[x] << endl; } cout << buffer << endl; // still print out junk in case return string( buffer, 5 );

i'm creating image preloader. works fine in browsers except firefox (testing firefox 10.0). input array of images called image_list . these images appended dynamically body of document , load callback attached, calls function update_progress . code follows: $(image_list).each(function() { var x = $('<img />') .load(function() {update_progress(percent_loaded += step);}) .attr('src', this) .appendto('body') .css('display', 'none'); .each(function() { if(this.complete) update_progress(percent_loaded += step); }); }); in firefox, load callback , update_progress never called. yet exact same code works fine in chrome , other browsers i've tested. there way detect when image has loaded in firefox? i first check see whether image has height, checking height property. if (the_image.height > 0) { // image loaded (possibly cached) } if have cached ...

android - getbluetoothservice() called with no bluetoothmanagercallback -

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
