Multiple Assignments

You can write 'normal' code like this:

 
 RECT r; 
 if GetWindowRect( hDlg, &r ): 
     g_iWindowX = r.left; 
     g_iWindowY = r.top; 
     g_iWindowWidth = r.right - r.left 
     g_iWindowHeight = r.bottom - r.top 
 

but you also have the ability to collapse the multiple assignments onto a single line, seperating them on both sides of '=' using commas. The equivalent code would be

 
 RECT r; 
 if GetWindowRect( hDlg, &r ): 
     g_iWindowX, g_iWindowY, g_iWindowWidth, g_iWindowHeight = r.left, r.top, r.right - r.left, r.bottom - r.top 
 

or you can split it into two statements:

 
 RECT r; 
 if GetWindowRect( hDlg, &r ): 
     g_iWindowX, g_iWindowY = r.left, r.top 
     g_iWindowWidth, g_iWindowHeight = r.right - r.left, r.bottom - r.top
