Question
What is the output of the following C++ code?#include <iostream>using namespace std;int main() { int x = 10; int y = 20; cout << (x++ + ++y) << endl; return 0;} *1 point303132Compiler error
Solution
The output of the given C++ code is 32.
Here's the step-by-step explanation:
-
The
x++operation is a post-increment operation. It means that the value ofxwill be used first and then incremented. So,x++will be 10. -
The
++yoperation is a pre-increment operation. It means that the value ofywill be incremented first and then used. So,++ywill be 21. -
The expression
(x++ + ++y)will be(10 + 21)which equals 31. -
However, remember that
xwas post-incremented, so after its value was used, it was incremented by 1. So, the final value ofxis now 11. -
Therefore, the output of the code will be the value of
x(which is now 11) plus the value ofy(which is 21), which equals 32.
