Can some one explane a for loop to me?

Answer 1

It's a looping process very effective when you want to manipulate data, usually many. Think firstly of the counter, or starting point variable as this is executed before our loop begins. This is our counter.

for (x = 0;

The test is assessed where if the condition is true, it will enter the code block or else cease looping.

for (x = 0; x < 2;

The code will execute twice in this case, but we need a something to make the counter increment.

for (x = 0; x < 2; x++)

In better terms, WHILE x is less than 2, enter code block and before you leave, add 1 to our counter.
If x is greater than 2, DON'T enter.

I hope I haven't baffled you, and sorry if I have.

Answer 2

@RANJOY KONSAM That's not JavaScript...
for (var i = 1; i <= 5; i++) {
document.write(i)
} // outputs 12345
document.write(i) // outputs 6, because i gets incremented but cannot proceed with the loop, so the loop stops at i = 5.

Answer 3

sure just look at the syntax of a loop: (example)
for(var i = 0; i < 5; i++) {...}
There are 3 segments
var i = 0; this is the first segment and it defines a variable the loop can count with
i < 5; this is the second segment and it's a condition, everytime a loop starts again this condition is checked the loop only continues as long this condition is true
i++; This is the third segment and is called at the end of the loop and adds 1 to i.

So we defined "i" as 0
then the loop starts and and the condition is checked. in this case it's true because 0 is smaller than 5.
Your code would run here
after all of your code "i" would be increased by 1
"i" is now 1.
the condition is checked again "i" is still smaller than 5
your code runs again
"i" is increased by 1 again
and the condition is checked again
...
...

It works like this until I is bigger than 5 or is 5

Answer 4

A loop statement allows us to execute a statement or group of statements multiple times .
consider this for loop
for(int i =1; i<=5; i++){
printf ("℅d ",i);
}
here the output will be 1 2 3 4 5
simply it means happening again and again or repeating

Answer 5

oh didn't consider the tag and simply give an example. my bad
