What is odd loop in 'C' program?
odd loop means at least the loop execute once.
What is the Difference between while and do while?
Both are programming commands. A do/while loop will execute at least once. A while loop may not execute at all.
Does a for loop always run at least once?
Yes, a for loop will always run at least once if the initial condition is true.
Does The statements within a while loop execute at least once?
No. If the loop condition is not satisfied then the loop would not be executed even once. while(condition) { ..... /statements ..... } here,when the condition is true then the statements will be executed. Otherwise they would be skipped without being executed. Only for do.. while loops this execution at least once holds good.
What is the minimum number of times a do- while loop is executed?
A do while loop is executed at least one time.
What is the difference between do while and while loop in java?
A do-while loop guarantees the body of the loop will execute at least once. A while loop might not execute at all. // this code will execute, even though the condition test will always evaluate to false do { // stuff }while(false); // this code will never execute because the condition test will always evaluate to false while(false) { // stuff }
The Do-While loop is what type of loop?
The do loop is similar to the while loop, except that the expression is not evaluated until after the do loop's code is executed. Therefore the code in a do loop is guaranteed to execute at least once. The following shows a do loop in action: do { System.out.println("Inside do while loop"); } while(false); The System.out.println() statement will print once, even though the expression evaluates to false. Remember, the do loop will always run the code in the loop body at least once. Be sure to note the use of the semicolon at the end of the while expression.
What type of loop always execute at least once?
A do-while loop always executes at least once, and works like this: do { //code, such as incrementing a value, printing text, etc. } while (expressionToEvaluate); a perfect example of this would be something like: <code> int i = 10; int counter = 0; do { counter+=i; i--; } while (i > 0); </code>
What is the difference between a while and a do while loop?
A do while loop will always execute at least once because the condition isn't checked until after the first iteration. A while loop condition is checked before the loop begins.Code Example:while(0) { /* any code here won't be executed */ } do { /* any code here will be executed exactly once */ } while(0);
What happens if the controlling expression in a do while loop is initially false?
The do-while loop is designed specifically for such situations, where you want the loop to execute once irrespective of the loop expression. The loop would execute once and then terminate because, the loop controlling expression is false. If you note the syntax properly do { ... ... ... } while(condition) The condition is executed only after one iteration of the loop and hence the code would execute once irrespective of the loop expression result.
What is the difference between a repeat until and a while do loop?
Repeat until loops run until a condition is true. They repeat at the end of the loop and they will always run at least once. While do loops will only run while a condition is true. They may not run at all.
What is main different between do while and while?
If you want to execute a statement which is in while loop at least one time you can use do- while loop. this is why because initially first statements will be executed then condition will be checked. but in case of while first condition will be check then statements will be executed
