Question

what advantage is procided by using a boolean found variable in a compound condition for a search loop

Answer 1

Answer:

- the notation while(!found) { ... } is semantically very clear

- you can initialize the found boolean as false

Explanation:

Within the while loop you will assign the compound condition to the 'found' variable. By initializing the variable with 'false' you ensure that the values used in the compound condition are valid.

Simplified example: read user input until 'Y' is pressed:

found = false;

while(!found) {

   userInput = readUserInput();

   found = (userInput == 'Y');

}
