Introduction
For those of us who need to port from Fortran:
In C++ there is no equivalent structure to Fortran's EQUIVALENCE
. (No pun intended!)
After doing some searching, I could not find an appropriate code, so I am suggesting the following "work-around" using the UNION
structure.
The basic idea is that the same portion of the memory is accessed by different data. (Variables or data types).
#include <iostream.h>
union mix_it
{
struct
{
double a;
double b;
double c;
} s;
double x[3];
} mix;
void main()
{
mix.s.a=12.1;
mix.s.b=12.2;
mix.s.c=12.3;
for (int i=0;i<3;i++) cout<<mix.x[i]<<endl;
}
