Question

A criticism of the break and continue statements is that each is unstructured. These statements can always be replaced by structured statements. Describe in general how you’d remove any break statement from a loop in a program and replace it with some structured equivalent. [Hint: The break statement leaves a loop from within the body ofthe loop. Another way to leave is by failing the loop-continuation test. Consider using in theloop-continuation test a second test that indicates “early exit because of a ‘break’ condition.”] Use the technique you developed here to remove the break statement from the program of Fig. 5.13.

for ( count - 1; count < 10; ++count )// loop 10 times
if ( count - 5)
break; // break loop only if count is 5
) //end for
cout << nBroke out of Toop WUCount
} /7 end main
<< Count << endl;
