Why are the statements in the body of a loop called conditionally executed statements?
These statements are called conditionally executed statements because the may or may not be executed. They will be executed while the boolean (true/false) statement in the beginning of the loop is true, but will not be executed when statement is false.
What is flag controlled while loop?
A while loop evaluates a conditional expression at the start of each iteration. If the conditional expression evaluates false, execution passes to the statement that immediately follows the body of the loop. If the conditional expression evaluates true, the body of the loop executes one iteration. When the end of the loop is reached, or a continue statement is encountered within the body of the loop, control passes back to the while statement where the conditional expression is re-evaluated. If a break statement is encountered within the body of the loop, the loop terminates and control passes to the next statement. If a return statement is encountered within the body of the loop, the loop terminates and control passes to the calling function.while (expression) {// repeats until the expression evaluates false}The braces are optional when the body of the loop is a simple statement. Compound statements must be enclosed in braces.A flag-controlled while loop has a simple conditional expression that evaluates a Boolean value:bool x;// ...while (x==true) { // flag-controlled loop// ...}}The above loop can also be written without the equality operator:while (x) { // flag-controlled loop // ...}Moreover, any integral type (such as int or char) will implicitly convert to a bool such that non-zero values evaluate true and zero evaluates false. As such, any integral type can be used in a flag-controlled loop.
How does a try statement determine which catch clause should be used to handle an exception?
When an exception is thrown within the body of a try statement, the catch clauses of the try statement are examined in the order in which they appear. The first catch clause that is capable of handling the exception that was thrown, is executed. The remaining catch clauses are ignored
What is the for loop in c plus plus?
In C, also in C++, the for loop executes zero or more times, until the test expression is false...for (init-expression; test-expression; loop-expression) statement;/* init-expression executed once, at beginning *//* statement executes zero or more times, until test-expression is false, test first *//* loop-expression evaluated at end of each iteration */
The body of for loop 1 Executes at least once 2 Executes zero or more times 3 Can not be executed more than100 times 4 Consists one and only one statement 5 Can not execute infinitely?
1. false 2. true 3. false 4. true, but that statement can be a compound statement, ie a statement-block between {} 5. false

What is difference between while and dowhile?
the test condition will be checked first after wards the body of the loop will be excuted in while statement and the the do while statement represented the body of the loop will be executed first and then the test condition will checked next

Do while loop in turbo c?
do {// statement;} while (expression);The statement body is executed at least once. At the end of each iteration, the expression is evaluated. If false (or 0), the loop terminates. If true (or non-zero), the statement body executes another iteration.Like any other loop structure, a do loop can be terminated by a break or return statement within the statement body. If a continue statement is encountered within the statement body, execution passes to the while clause where expression is re-evaluated.To understand how a do loop differs from a while loop, compare the following:int x;x = 0;do {printf ("%d ", ++x);} while (x

Is do-while loop executed only if the condition is true?
First the body is executed, then the condition gets checked.
What is difference between for loop statement and do while statement in c language?
The for loop has an initializer, an end condition, a loop expression, and a body. The initializer always runs. If the end condition is not satisified, the loop ends or never starts. The loop expression runs at the end of each iteration. Note that the body of a for loop can run no times. The do while statement has a body and an end condition. The body is executed, and then the end condition determines if the loop will iterate. Like the for loop, the loop expression runs at the end of each iteration. Note that the body of a do while loop will run at least one time.
What are the statements executed within a loop collectively known as?
The body of the loop.
What are the three major function to be executed at the crime of a scene?
Secure the crime scene to preserve evidence and prevent contamination. Document the scene through photography, sketching, and note-taking to record the location and condition of evidence. Collect physical evidence following proper procedures such as bagging and labeling to ensure preservation and chain of custody.
Can you say that no force acts on a body at rest?
You could say it if you want, but it's not a true statement. Without investigating the situation in detail, we know immediately that every object on Earth, whether at rest or in motion, is acted upon by a gravitational force directed toward the center of the Earth. There are other exceptions to the statement, but we've already disproven it, utterly and easily.
