What is the name of the "-->" operator? (Stackoverflow), stackoverflow

Question:

After reading Hidden Features and Dark Corners of C ++/STL on comp. lang. c ++. moderated, I was completely surprised that it compiled and worked in both Visual Studio 2008 and G ++ 4.4.

The code:

#include <stdio.h>int main(){     int x = 10;     while( x --> 0 ) // x goes to 0     {       printf("%d ", x);     }}

I 'd assume this is C, since it works in GCC as well. Where is this defined in the standard, and where has it come from?

Answer:

That's not an operator-->. That's two separate operators,--And>.

The condition code is decrementingx, While returningx'S original (not decremented) value, and then comparing the original value0Using>Operator.

To better understand, the statement cocould be written as follows:

while( (x--) > 0 )
