For example, the first time through the loop, value=3. Control transfers to line 22 where b gets incremented. Then it falls through to line 25 and increments a. Then it breaks out of the switch statement. So your paper now looks like this: a | b | c d Continue the same way with...
switch (nodeTag(plan)) { case T_Result: pname = sname = "Result"; break; case T_ProjectSet: pname = sname = "ProjectSet"; break; case T_ModifyTable: sname = "ModifyTable"; switch (((ModifyTable *) plan)->operation) { case CMD_INSERT: pname = operation = "Insert"; break; ...
Example: int a,b,c; In this statement,comma is a separator and tells to the compiler that these (a, b, and c) are three different variables. 2) Comma (,) as an operator Sometimes we assign multiple values to a variable using comma, in that case comma is known as operator. ...
