while loop

# simple while loop python.
input                                      output
a=1                                        1
while a<=10:                               4                               
      print(a)                             7
      a=a+3                                10
# here a=a+3 can be written as 'a+=3'

while loop

While(condition is true) {

// Code                                         // The block keeps executing as long as the condition is true

// Code

}

While Loop

A while loop statement in Java programming language repeatedly executes a target statement as long as a given condition is true. 

Syntax : 
while(Boolean_expression) {
   // Statements
}
Here, statement(s) may be a single statement or a block of statements. The condition may be any expression, and true is any non zero value. 

When executing, if the boolean_expression result is true, then the actions inside the loop will be executed. This will continue as long as the expression result is true.

When the condition becomes false, program control passes to the line immediately following the loop.

while loop

#input                                    # output
a=6                                        quantity of commodity=   
b=int(input("quantity of commodity="))     sampoo 
i=1                                        sampoo
while i <= b :                             sampoo
    if i>a:                                sampoo
        print("hello")                     sampoo
        break                              sampoo
    print('sampoo')                        hello  (it is printed when a<=7) 
    i+=1                                   thank you for coming
print("thank you for coming")

while loop

Create a loop that runs as long as i is less than 10.

var i = 0;

while(i < 10) {
	console.log(i); i++
}

Do..While Loop

A do...while loop is similar to a while loop, except that a do...while loop is guaranteed to execute at least one time. 

Syntax : 
do {
   // Statements
}while(Boolean_expression);
Notice that the Boolean expression appears at the end of the loop, so the statements in the loop execute once before the Boolean is tested.

If the Boolean expression is true, the control jumps back up to do statement, and the statements in the loop execute again. This process repeats until the Boolean expression is false.

while loop

while(true)
{
	do this;
}

while loop

let dice = Math.trunc(Math.random() * 6) + 1;

while (dice !== 6) {
  console.log(`You rolled a ${dice}`);
  dice = Math.trunc(Math.random() * 6) + 1;
  if (dice === 6) {
    console.log(`loop is ended`);
  }
}

while loop

Create a loop that runs as long as i is less than 10, but increase i with 2 each time.

var i = 0

while(i < 10){
	console.log(i);
    i = i + 2;
}

Example of a Do..While Loop

public class Test {

   public static void main(String args[]) {
      int x = 10;

      do {
         System.out.print("value of x : " + x );
         x++;
         System.out.print("
");
      }while( x < 20 );
   }
}

while loop

while(condition)
{ 
code it here
}

Example of While Loop

public class Test {

   public static void main(String args[]) {
      int x = 10;

      while( x < 20 ) {
         System.out.print("value of x : " + x );
         x++;
         System.out.print("
");
      }
   }
}

do while loop

let i = true;
do{
	i= true; or // i = false;
}while(i == true);

what are while loops

# There are 2 types of loops in python
# while loops and for loops
# a while loops continues for an indefinite amount of time
# until a condition is met:

x = 0
y = 3
while x < y:
    print(x)
    x = x + 1

>>> 0
>>> 1
>>> 2

# The number of iterations (loops) that the while loop above
# performs is dependent on the value of y and can therefore change

######################################################################

# below is the equivalent for loop:
for i in range(0, 3):
    print(i)

>>> 0
>>> 1
>>> 2

# The for loop above is a definite loop which means that it will always
# loop three times (because of the range I have set)
# notice that the loop begins at 0 and goes up to one less than 3.
