Well I encountered a problem , Maybe someone could help me out ? What I want to do is to access other class variables or functions . Here is the code example I have came up with : C++ The problem is in the A class it can't see the binst (binst' : undeclared identifier) declaring it before the A class , produce compiler error like : ('binst' uses undefined class 'B'). So what is the best way to solve it ? Thanks in advance.
#include <stdio.h>
class A;
class B;
class A
{
public:
int var1;
void Change()
{
binst.var2 = 10;
}
};
A ainst;
class B
{
public:
int var2;
void Change()
{
ainst.var1 = 20;
}
};
B binst;
int main()
{
printf(" var1 = %d\n",ainst.var1);
printf(" var2 = %d\n",binst.var1);
//let's change and see new things
ainst.Change();
binst.Change();
printf(" var1 = %d\n",ainst.var1);
printf(" var2 = %d\n",binst.var1);
return 0;
}
