while loop in c

while loop in c

e.g. ex: The program is an example of infinite while loop. Loops are used in programming to execute a block of code repeatedly until a specified condition is met. The while statement executes a statement or a block of statements while a specified Boolean expression evaluates to true.Because that expression is evaluated before each execution of the loop, a while loop executes zero or more times. A Loop executes the sequence of statements many times until the stated condition becomes false. if(age>18) step2: If the condition returns true then the statements inside the body of while loop are executed else control comes out of the loop. Since the value of the variable var is same (there is no ++ or – operator used on this variable, inside the body of loop) the condition var<=2 will be true forever and the loop would never terminate. your explanation is terrific . If the test expression is true, statements inside the body of. The condition may be any expression, and true is any nonzero value. printf("%d",i); step3: The value of count is incremented using ++ operator then it has been tested again for the loop condition. Just like relational operators (<, >, >=, <=, ! Let’s look at the “for loop” from the example: We first start by setting the variable i to 0. Ltd. All rights reserved. I have doubt regarding while loop and my question is, CAN we use COMMA( , ) in while loop and AND(&&). { The following scenarios are valid : -using AND(&&) operator, which means both the conditions should be true. This is where we start to count. This process goes on until the test expression becomes false. while (C# Reference) 05/28/2018; 2 minutes to read +6; In this article. In this example we are testing multiple conditions using logical operator inside while loop. }, on the other hand while statement is being used for loop operation for example When the condition becomes false, the program control passes to the line immediately following the loop. do while loop. The while loop loops through a block of code as long as a specified condition is True: Syntax while (condition) { // code block to be executed} In the example below, the code in the loop will run, over and over again, as long as a variable (i) is less than 5: Privacy Policy . tnx, if statement is use to define condition , if condition holds true the statement will be executed otherwise not. In the previous tutorial, we learned about for loop. Note: A single instruction can be placed behind the “for loop” without the curly brackets. How any language is created?
