Question

WHAT IS THE meaning of y=-x++

Answer 1

- (minus) sign is for making the output negative

x++ is used for incrementing the value of x by 1. But it is post increment operation, it won't make any difference in the value of y. x will increase by 1.
Example:

x=1;
y=-x++;
print(y); //output => -1
print(x);. //output => 2
