Simple: Why does x = ++x + x++ give me the wrong answer?[^]

BTW: in future, don't put your code as the subject line - that's what "What I have tried" is there for. The subject line should be short and sweet, and quick overview of the problem in English as much as possible. Perhaps "x++ giving wrong answer" or similar?

You are in gray zone: the code is legal, but unpredictable.

C++

y=x++ + ++x + ++x + ++x + ++x;

The compiler is free to reorder what is in this code.
for x=10, y can be anywhere between 50 and 75.
The only advice is: never mess with multiple increment/decrement operations in a single line of code.

#include<studio.h> main() { int x=10, y; print("enter a number"); scan ("%d", &x); y=x++ + ++x + ++x + ++x + ++x; print("result:%d", y):;
