its a simple question

Hi

in the following condition:

if (x>0) { ... }

the curly brackets are executed if the value of x is above 0.

What is the situation if you have just:

if(x){ ... } ?

Does it mean, 'if the value of x IS 0 then execute the code in the brackets' or does it mean the oposite?

Stupid question I know but ....

Thanks
Buck

Hi
if(x > 0) {....} /* this will perform process if x is greater than zero*/

if(x) {....} /*this will perform process if x is not equal to zero...but will perorm when x is less than zero i.e. ( - 1 )*/

when there is only one operand in the comparison...in C true equates to a non zero value and zero is false....therefore in second if statement if(x) means if x is not equal zero (true) process will perform....also curlies are optional when there is only one operation is required after comparison statement...

Code:

---

  if(x)
    printf("%d", x);

/*when 2 or more*/
  if(x)
  {
    printf("%d", x);
    do something else;
  }
