Here's an example:
#include <stdio.h>
int main()
{
int x = 10;
while( x --> 0 ) // x goes to 0
{
printf("%d ", x);
}
}
Answer
--> is not an operator. It is in fact two separate operators, -- and >.
The conditional's code decrements x, while returning x's original (not decremented) value, and then compares the original value with 0 using the > operator.
To better understand, the statement could be written as follows:
while( (x--) > 0 )
or
#include <stdio.h>
int main()
{
int x = 10;
while( (x--) > 0 ) // x goes to 0
{
printf("%d ", x);
}
}
