 All of these statements change the flow of control in a c++ program.  They change the behavior of control structures and therefore make it more difficult to understand the final flow of control in a program.  For these reasons, the use of these statements is heavily restricted.
+===== Summary =====
+  * Do not use continue statements
+  * Do not use goto statements
+  * Only use break statements in switch statements
+  * Only use a single return statement per function. It must be the last statement in the function.
+  * All functions should have a return statement.
 ===== goto =====
+The use of a goto statement transfers code to a predefined location in the program.  This can produce code which is difficult to follow and is therefore prohibited by the local style guide.
 ===== continue =====
+The continue statement allows a programmer to skip the remaining statements in a control structure.  When employed in a loop, this will immediately transfer control to the end of the loop, however additional loop iterations may occur.
+The use of continue statements can cause surprising flow of control to those who are unaccustomed to their use.
+The use of continue statements is not permitted in the local style guide.
 ===== break =====
+The break statement causes control to be transferred to the end of the innermost control structure. It can be used to exit a loop without using the normal loop conditional statement.   Such a use will cause those unfamiliar with this programming style to misread the code.
+Break is the primary method to exit a case or set of cases in a switch statement.
+The local style guide prohibits the use of **break** except in switch statements.
 ===== return =====
