c++ - xtgmath.h has compile-time errors -


i trying compile older c++ program in visual studio 2013 professional. encountering compile error, visual studio saying there syntax errors in xtgmath.h file. complete log is:

1> fill.cpp 1>c:\program files (x86)\microsoft visual studio 12.0\vc\include\xtgmath.h(179): error c2059: syntax error : '('

1>c:\program files (x86)\microsoft visual studio 12.0\vc\include\xtgmath.h(179): error c2027: use of undefined type 'std::enable_if'

1>c:\program files (x86)\microsoft visual studio 12.0\vc\include\xtgmath.h(179): error c2059: syntax error : ')'

i have tried several different things others have recommended, none of seems work. tried run preprocessor on source file , examine generated code, offered no insights. have idea what's going wrong here?

i have exact same error -- working old code , trying compile under vs2013. me problem tied line of xtgmath.h:

_generic_math1(round, _crtspecial)

i nailed down round being predefined in stdafx.h. in vs2013, round built in function , having definition override caused compile errors.

to solve have commented out round definition in stdafx.h.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.

javascript - IE11 incompatibility with jQuery's 'readonly'? -

the code i'm running has no issues in firefox, or chrome. user typing 1 textbox, tabs next , can continue typing that. when run webpage on ie11, user tabs next textbox , can't type in. textbox has double-clicked before user can insert anything. i've googled , seems ie give problems when using older jquery (i.e. prefers 'prop' 'attr' ). in code below jquery's readonly keyword being used in way ie11 no longer recognise/accept? i assume issue readonly , removeclass('ignore') working expected. //when focus on textbox 1 $("#field1").focus(function() { //remove readonly property textbox 1 $('#field1').prop('readonly', false).removeclass('ignore'); //add readonly property other textboxes $('#field2, #field3, #field4') .prop('readonly', 'readonly').addclass('ignore').val(''); }); i'm using jquery 2.1.3 ...
