Why is the condition true?

Question

C++ / C#

#include<iostream>
int main()
{
   int a = 6;
   if(1 < a < 5)std::cout<<"IN";
}

Answer 1

Because 1 < a= 1 (first operator)
AND = 1 (true) (second operator) That is, first the first operator is calculated , and what happened goes to the second operator . Write1 < 5
if(1 < a && a < 5)std::cout<<"IN";
