5.4 Can we exit a loop early if something happens?

A. Introduction The third and last type of flow is all about repetitions: how to repeat some actions exact N times? or how to repeat some actions until certain status is achieved? There are actually three types of statements: for loops, while loops and do loops. B. Watch( Slides ) C. Try: Print out a multiplication table from 1 x 1 = 1 .... to 9 x 9 = 81. (Hint: you need a for loop inside a for loop)

A. Introduction You were asked to use for-loops to print out a multiplication table, for-loops and nested for-loops are widely used for many applications. Here are some examples. B. Watch( Slides ) C. Try to print out the upper half or the lower half of a multiplication table like this:

A. Introduction do loops are essentially same at while loops except that they will run at least once. All three types of loops can be converted into each other... Which one to choose? B. Watch( slides ) C. Try this: Write a do loop that reads integers and computes their sum. Stop when reading a zero or the same value twice in a row. For example, if the input is 1 2 3 4 4, then the sum is 14 and the loop stops.
