What is the difference between a loop and a conditional?
A conditional Statement is a statement which is used in place of a if-else-if statement. If the condition is true, it will execute expression 1 else it will execute expression 2. A loop on the other hand will do the same instructions again and again until the condition is satisfied.
How are conditionals and loops the same?
Conditional statements with the proper comparison and boolean operators allow the creation of alternate execution paths in the code. Loops allow repeated execution of the same set of statements on all the objects within a sequence. Using an index based for loop is best suited for making changes to items within a list.
What is the difference between if-else and if?
if vs if else The if statement is a decision-making structure that consists of an expression followed by one or more statements. The if else is a decision-making structure in which the if statement can be followed by an optional else statement that executes when the expression is false.
What is a condition in a loop?
In while loop, a condition is evaluated before processing a body of the loop. If a condition is true then and only then the body of a loop is executed. Once the condition becomes false, the control goes out of the loop. After exiting the loop, the control goes to the statements which are immediately after the loop.
Can if else and while loop be used interchangeably explain?
Well the if is a one time branching operation and the while loop is as the name implies a loop. Meaning an if statement gives you once the possibility to do something or not (or something else). Whereas a while loop does things as long as the condition is true.
What is the difference between for loop and while loop?
The difference between for loop and while loop is that in for loop the number of iterations to be done is already known and is used to obtain a certain result whereas in while loop the command runs until a certain condition is reached and the statement is proved to be false.
Is if-else a loop?
The if/else loop is a conditional statement (do this or else do that). You use this statement to execute some code if the condition is true and another code if the condition is false.
What is the difference between while and do while loop?
16 Answers. The do while loop executes the content of the loop once before checking the condition of the while. Whereas a while loop will check the condition first before executing the content.
What is the difference between for and while loop in Python with example?
for loops is used when you have definite itteration (the number of iterations is known). while loop is an indefinite itteration that is used when a loop repeats unkown number of times and end when some condition is met.
What is the difference between if else and switch case?
In the case of ‘if-else’ statement, either the ‘if’ block or the ‘else’ block will be executed based on the condition. In the case of the ‘switch’ statement, one case after another will be executed until the break keyword is not found, or the default statement is executed.
What are the similarity and difference between while loop and for loop?
Here are few differences:
| For loop | While loop |
|---|---|
| Once the statement(s) is executed then after increment is done. | Increment can be done before or after the execution of the statement(s). |
| It is normally used when the number of iterations is known. | It is normally used when the number of iterations is unknown. |
What is if else fi?
if..else..fi allows to make choice based on the success or failure of a command. For example, find out if file exists (true condition) or not (false condition) and take action based on a condition result.
What is a bash loop?
Bash While Loop is a loop statement used to execute a block of statements repeatedly based on the boolean result of an expression, for as long as the expression evaluates to TRUE.
What is a loop in Excel?
Looping is one of the most powerful programming techniques. A loop in Excel VBA enables you to loop through a range of cells with just a few codes lines. You can use a single loop to loop through a one-dimensional range of cells.
