The reason behind the ; is written after loop statement.

[Starx]

Why semi colon is written after loop statement, in c.

[zuko32]

There is actually a loop statement that we have to write ; and this is the do-while loop that exists in a lot of languages and has this form:

do{           
   statements;                    

}while( condition );

Now, for loops like for, while, if they are empty, i.e. they have no statements in the body, they should be terminated with a ;.

The semi-colon must appear at the end of each statement. The do-loop statement is not complete until the ) of the while so you need a semicolon to tell the compiler the statement is complete.

@starx please show us an example of the kind of statement you're asking about.

[AX3M]

Either of two reasons

I assume, by "after", you mean "at the end (of a loop statement)."

The reason a semicolon (;) is written "after" or "at the end of" a loop statement is either that...

a. It is a do-while loop.

do
   x += y;
while (x < y);

b. For other types of loops, it or the last part of the loop has only one line of code to execute, in its body.

if (x < y)
   x += y;

I hope this is the answer you're looking for.
