Answer 1

for(int i = 0; i <10; i++)

Answer 2

you mean the trick?

int i = 10;
while (0 <-- i)
{
// Do stuff.
}

Answer 3

yea

Answer 4

like for (int i=0; i<=something; i++);
{
}

Answer 5

Shouldn't add a semicolon between the end of the for statement and the opening brace.

Answer 6

yea , but like what does i++ mean

Answer 7

each time it goes through loop i value is increased by 1 so you could write i = i + 1 or i+=1

Answer 8

ohhhhhh ! ok

Answer 9

Answer 10

The ++ operator in C and C derived languages is the auto increment operator. -- is the auto decrement operator. If you have an int(eger) variable c, ++c would increment c before it is evaluated. c++ would evaluate the value of c and then increment it. They're actually called pre/post auto increment/decrement operators.

Answer 11

what do you mean increment before it is evaluated

Answer 12

{
int c = 9;
printf( "%d\n", ++c ); /* will print 10 */
printf( "%d\n", c++); /* will print 10 */
printf( "%d\n", c ); /* will print 11 */
}

Answer 13

also, something like i = ++i + i++ - --i - i-- would be undefined behavior :-P
