Question

Consider the following code;int limit;int reps = 0;cin >> limit;while (reps < limit){ cin >> entry; triple = entry * 3; cout << triple; reps++;}cout << endl;This code is an example of a(n) ____ while loop.a. flag-controlledb. counter-controlledc. EOF-controlledd. sentinel-controlled

Answer 1

Answer:  

The answer is "option b"  

Explanation:  

In the given code a while loop is defined, It is also known as the counter controlled loop. This loop is used when we know the number of loop iterations occurs. Other options are wrong that are explained as follows:  

• In option a, The flag-controlled loop is used in a while loop, which gives Boolean value.  
• In option c, The EOF controlled loop controls system causes and provides continuous execution to statement or group of statements.  
• In option d, It is opposite to the counter controlled loop. In this loop, we don't know about iterations to occur.
