26. What is the output of this program?
    

     #include <iostream>
        #include <cstdlib>
        using namespace std;
        int main()
        {
            cout << RAND_MAX << endl;
        }
    

1. 1. Depends on the compiler

   
   
   

   2. Compilation Error

   
   
   

   3. Runtime Error

   
   
   

   4. Garbage value

   
   
   

   5. None of these

   NA

   Correct Option: D

   As the declared number is integer, It will produce the random number from 0​ to RAND_MAX. The value of RAND_MAX is library-dependent, but is guaranteed to be at least 32767 on any standard library implementation.
