- int foo(int a)
- {
-    int b = 5;
-    return a + b;
- }

-    return foo(1);
- }

-The subroutine bar() calls foo().  When bar() calls foo(), it passes the constant 1.  Within bar(), 1 is an actual parameter to foo().  Within foo(), a is a formal parameter which references the actual parameter 1 from bar().
