### difference between for and while loops

whats is the output that statement

for( x=1;x<=10;x=+1)

cout<<x<<endl;

i know the outpout will b 12345678910

but for this statement i did not get it

x=8
while(x<10)
x=x+1
cout<<x;

dont know what would be the output

910

Btw your syntax is wrong. If you want to increment a variable by one, just call the increment operator:

X++

=+ is not valid syntax. Is it actually +=.
yeah this one is just error in typing but the second statement i am trying to figure out what would be the output
If you use braces for 'while' the output will be
 `910`

otherwise if you use above code,the output will be
 `10`

 ``123`` ``````for( x=1;x<=10;x=+1) cout<

1 (on a new line because of endl) infinitely, x = +1 mean "x equals positive one", therefore x will never be anything but 1.

 ``1234`` ``````x=8 while(x<10) x=x+1 cout<

10, the cout statement is not a part of the loop (no curly braces).
If you use braces for 'while' the output will be
910

how did u get to that....sorry its my first class in c++
 ``1234567`` ``````int x = 8; // Declare x as an integer and set it to 8 while (x < 10) // While x is less than 10 .. { x = x+1; //Add one to x cout << x; //And then print x }``````

It will loop over the stuff inside the { }, each time checking to see if `x < 10` is still true. Once x is 10, it isn't anymore, and it'll move past it. So the first time, it'll add one, then print x. "9". 9 is less than 10, so it'll do it again. Add one, and print it. "10". 10 is not less than 10 so it doesn't do it again. Final output is "910"

 ``123456`` ``````int x=8; while(x<10) { x=x+1//line 1 cout<

Above one using braces.
Because 'while' or 'if-else' or 'switch' or 'for' control structures execute only one line of code below to them ,if you dont use braces.
in your code the while(x<10) execute for only x=x+1;
cout<<x; is not part of while loop
ok i got you but how about the first one with for for( x=1;x<=10;x=+1)

cout<<x<<endl;

the cout is a part of the loop
The normal idiom for doing something 10 times is:

 ``1234`` ``````for( int x=0;x<10;x++) { cout << x+1 << endl; //do your stuff here }``````

As a while loop:

 ``12345`` ``````int x=0; while (x<10) { cout << x+1 << endl; x++; }``````

And that while can be shortened like this:

 ``1234`` ``````int x=0; while (x<10) { cout << ++x << endl; }``````

but in case i have curly braces for the while statemnt why 10 as an answer as long as 10<10 is not impossible
