what is the usage of " ; " at the end of this code ?

Question

for(int i = 1; i< 10;i++);

Answer 1

That semicolon tells us that the for-loop is "bodyless". Meaning no extra instruction was to be carried out other than the ones inside the loop construct, which only defines and increments a local (in loop scope) counter variable <i>.

Answer 2

Hey alireza mohammadian
As all said it is used to to terminate the statement , but here it is used as null statement ( ; ) !
null statement :- A statement without any executable expression !

Above " for " loop written as :
for(int i=1;i<10;i++)
; //nothing happens on this line

Answer 3

The ';' was created to raise your stress levels and insult your programming skills.

Answer 4

there is no error for using for(int i=1;i<10;i++) ; although it misleads the " for " but it gives correct output !
in your code " i " should declare before " for " loop , " i " after cout can't have scope of that variable ;
