I am working on mobile communication Simulator based on C language. I have two different IPs which are stored as Strings in different format.

1. For User it is XYZ[20]
2. For Access Gateway, it is ABC[No. of Users][20]

Now, I need to compare both for one algorithm. but I am confused that how should I do them as both are different arrays. Is there any way to compare both 1D with 2D array ?

Answer 1

#include <string.h>
...
for ( int i = 0; i < num_users; i++ )
{
  if ( strcmp( ABC[i], XYZ ) == 0 )
  {
    // strings are equal
  }
  else
  {
    // strings are not equal
  }
}

ABC[i] is the i'th string stored in ABC.
