sometimes i don't understand FOR loop

Question

for ( x = 0 ; x < 5 ; x++ )

what is x++ means here i mean what will be its value in each iteration , how can i print the value and why there is a need of using x++ here
can we skip it or use it inside the for loop statements ?
for ( condition )
{
x++; // here
}

and sometimes we also use like this
for ( x=0 ; x <5 ; x++ ) // here
{
x++ ; // here
}
what if we don't use it like in while and do while we mostly increment inside the loops .

i hope you guys understand my question..

Answer 1

Okay.

So with the for loop, I believe you can leave out the 'x++'. I Believe you just have to remember the semicolons. you must put it inside the loop though, unless you want an endless loop...

you can check to see if I am correct in the code playground, I do really hope this helps.

Here's an example of what the heck in talking about.

for(x=0; x < 5; ;)
{
//do something
x++;
}

Answer 3

No it will be simple first increment with 1 bcz of loop simple 1,2,3,....9.... K.. Then bcz of i++ afterwards it will increase the result by 1.. So as soon as the result i.e 1,3,5,7,9 becomes more than 10 the loop will be terminated.. 1 i=1 then again enter for loop then i++ means it becomes 2 after then again i++ it becomes 3 k.. Similarly then I =3 now i++ of for loop it becomes 4 and again i++ it bcms 5 so now i=5...

Answer 4

It's a syntax of for loop.
Bcz the syntax of for loop is for(value;condition;increment/decrement)
It's better to use increment and decrement within the for loop..

Answer 5

and when that increment works ? can anyone explain me with an example please

Answer 6

Increment works when you have to increase the value..
Like you want to print the value from 0-9..
for(int i=0;i<10;i++)
To reverse the order use i--.. And use i=10and put condition

Answer 7

and what if we use increments like this... for(int i=0; i<10;i++)
{
i++ ;
}
what will be the answer ?

Answer 8

do you mean its like this ?

for ( i= 0 ; i< 10; i++)// here i will be 1 3 5 7 9
{

i++ ; // 2 4 6 8

}
