Different Types of Loops
What are the 3 types of loops?
Visual Basic has three main types of loops: for.. next loops, do loops and while loops.
- for – loops through a block of code a number of times.
- for/in – loops through the properties of an object.
- for/of – loops through the values of an iterable object.
- while – loops through a block of code while a specified condition is true.
What is while loop example?
A “While” Loop is used to repeat a specific block of code an unknown number of times, until a condition is met. For example, if we want to ask a user for a number between 1 and 10, we don’t know how many times the user may enter a larger number, so we keep asking “while the number is not between 1 and 10”.
What is the difference between for and while do loops?
while — loops through a block of code once; then the condition is evaluated. If the condition is true, the statement is repeated as long as the specified condition is true. for — loops through a block of code until the counter reaches a specified number.
What are two types of loop?
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. For loops are used when you know how many times you want to run an algorithm before stopping.
What are the 2 types of loops?
There are mainly two types of loops:
- Entry Controlled loops: In this type of loops the test condition is tested before entering the loop body. For Loop and While Loop are entry controlled loops.
- Exit Controlled Loops: In this type of loops the test condition is tested or evaluated at the end of loop body.
Can I use for in loop?
Either way, for … in carries with it no connotation of order. If you care about order, be explicit about it and use a regular for loop with an index.
Which loop is faster in C language?
Some situation, we can use while loop or do-while loop interchangeably. One of my friend told me that such situation we should use do-while loop. Because it is faster than while.
HOW DO FOR loops work?
A “For” Loop is used to repeat a specific block of code a known number of times. For example, if we want to check the grade of every student in the class, we loop from 1 to that number. When the number of times is not known before hand, we use a “While” loop.
What is a counting loop?
A common form of loop is the counting loop, in which the loop repeats a fixed number of times. … A counting loop typically uses a variable to count from some initial value to some final value. This variable is often called the index variable.
