c++ - Calling member functions of a class object which is present in header file included -

i new forum wanted call member function of included header file..here code have written

#include<stdio.h> #include "abc.h"  cabc *a;//cabc class present in abc.h  int main(int argc,char **argv) { int i=10; float j=15.5; bool x; x=a->method(i,j);//method member function of cabc if(x) {     printf("working correctly"); } else {     printf("not working"); } 

}

if compile using

g++ -i/path/to/include code.cpp 

i error

/tmp/cc5jglff.o: in function `main':  code.cpp:(.text+0x3d): undefined reference `cabc::method(int,float)'  collect2: ld returned 1 exit status 

i tried giving

x=a::method(i,j); 

for not class or namespace

please can tell me doing correctly or not?

it looks though forgetting include implementation source/object.

try this:

g++ -i/path/to/include abc.cpp code.cpp 

as long implementation class abc.h corresponds abc.cpp.
