What loops are indefinite?
An indefinite loop is a loop that waits for some condition to become true. In general, it’s not obvious how many iterations it takes. For example, you might be looking for the first number that is divisible by 2, 3, 5, 7, and 11. You could compute this ahead of time, but it’s not easy.
How does one differentiate between a definite and an indefinite loop?
Definite: a set of instructions is repeated a specific number of times. It is implemented by using count-controlled loops, such as for loops. Indefinite: a set of instructions is repeated until a condition is met. It is implemented by using condition-controlled loops, such as while loops.
What are the two types of loops?
Two major types of loops are FOR LOOPS and WHILE LOOPS. A For loop will run a preset number of times whereas a While loop will run a variable number of times.
What three components are needed for a definite loop?
Some languages require a separate declaration of the control variable, some do not. Another form was popularized by the C programming language. It requires 3 parts: the initialization (loop variant), the condition, and the advancement to the next iteration.
What is an example of a definite loop?
In definite loops, the number of iterations is known before we start the execution of the body of the loop. Example: repeat for 10 times printing out a *. Example: while the user does not decide it is time to stop, print out a * and ask the user whether he wants to stop.
What is the difference between a definite loop and an indefinite loop?
A loop is a block of code that would repeat for a specified number of times or until some condition is satisfied. A definite loop is a loop in which the number of times it is going to execute is known in advance before entering the loop.
When do we know the number of iterations in an indefinite loop?
In indefinite loops, the number of iterations is not known before we start to execute the body of the loop, but depends on when a certain condition becomes true (and this depends on what happens in the body of the loop) Example: while the user does not decide it is time to stop, print out a * and ask the user whether he wants to stop.
What’s the difference between a loop and a DO WHILE LOOP?
Typically, an indefinite loop is going to be executed until some condition is satisfied. While loops and do-while loops are commonly used to implement indefinite loops.
How many indefinite loops are there in Java?
There are two indefinite loops: 1 while loop 2 do-while loop More
