 Hello Folks!!!!
 i have one interesting question over here ……….
 Is it possible to create a generic pointer (generic pointer to member functions) which can point to all the member functions of a class
 Ex : Code: ( cpp )
 class abc(){ int fun1(int a){ //Body of fun1 } float fun2(float a){ //Body of fun2 } }; //End of class
 1
 2
 3
 4
 5
 6
 7
 8
 class abc(){ 
 int fun1(int a){ 
 //Body of fun1 
 } 
 float fun2(float a){ 
 //Body of fun2 
 } 
 }; //End of class
 here a generic pointer which can hold the address of functions fun1 as well as fun2
 Comments will be appreciated.!!!!

 Assalmaulaikum Asad, This is not wot i wanted… i wanted to have a pointer to a member function and not a pointer to object….
 Ex: int (abc:: *ptr)(int );here ptr is an pointer to a member function of the class…
 something like this which is very generic and can hold the address of every function of that class..

 walakum salam nadeem bhai!!!
 Now you give correct requirement!!!
 we can declare a pointer to anf member functions which has any number and any type of arguments. But return type will be same .
 int (abc:: *ptr) ( . . .)
 1
 int (abc:: *ptr) ( . . .)
 I did’nt try to take return type as as template. I dont template will woek or not…
