#include <iostream> using namespace std; int main() { int a=1 ,b; a=b; cout << b+a; return 0; }

Why this code outputs 16

b has an undefined value that happens to be 8.

Zen is there any specific reason why it has value of 8 only? I tried playing with the code a bit but everytime the undefined var has value of 8 meaning it isn't random 🤔

First you assign 1 to a Then you make b equal to a so b now is 1 cout << b+a prints the sum of a and b => a=1; b=1 ==> a+b =2
