What is the name of the “-->” operator in C/C++?

Question

Here is working code on gcc compiler but I dont know the name of the symbol "--> ."

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

Answer 1

The condition mentioned in while "if x is greater than zero then decrease the value of x by 1 and print the value of x".
while (x-- > 0) or while (x -->0) // both are same.
