What is the output of C++ program given below?

#include<iostream> using namespace std; int main() { int y=8,x=6; (x=5)&&(x=7) ? y=1:y=2; cout<<x<<"_"<<y; }

Note: _ (underscore is used in cout statement to differentiate x & y value.

 Though variables x,y are intialized with 6, 8 respectively. Due to below statement the values of x,y are changed. (x=5)&&(x=7) ? y=1:y=2; Conditional operator (?:) follows right to left associativity. && operator follows left to right associativity. = opeartor always returns true. Evaluate the condition (x=5)&&(x=7) first. proceed left to right due to && Hence x=7 finally, and condition returns true because (true&&true implies true) Hence y=1; Which prints 7_1
