qt - send reference qplaintextedit to C++ constructor class -


i need send reference qplaintextedit c++ class analizador add lines qplaintextedit class. add include <qplaintextedit> class, create qplaintextedit graphic interface , call constructor function 

analizador *anal=new analizador(ui->textprogres);

the constructor function is: 

analizador(qplaintextedit* text);

the compiler throw error :

mainwindow.cpp:23: error: undefined reference `analizador::analizador(qplaintextedit*)'

so guess error because i'm not sending pointer constructor function don't know how access pointers of qplaintextedit

ps. i'm new in qt , c++

in case, compiler complains cannot find definition of analizador constructor when tries link application.

make sure have written definition of analizador::analizador(qplaintextedit*) constructor.

if have written constructor still gets issue, cpp file constructor exists may not have got compiled. if using qtcreator, try build -> run qmake , build -> rebuild all

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.
