       using namespace std;
       #define Maximum 100
       int main()
       {
           int n;
           num = ++Maximum;
           cout << n;
           return 0;
       }
   

1. 1. 100

   
   
   

   2. Compilation Error

   
   
   

   3. Runtime Error

   NA

   Correct Option: B

   Macro Preprocessor only replaces occurance of macro symbol with macro symbol value, So we can’t increment the value.
   Compilation Error
   

   In function 'int main()':
   7:9: error: 'num' was not declared in this scope
   3:21: error: lvalue required as increment operand
   7:17: note: in expansion of macro 'Maximum'

3. What is the output of this program?
   

   #include 
       using namespace std;
       #define Function(id) cout << "The value of " #id " is "<    int main()
       {
           int Num = 100;
           Function(Num);
           return 0;
       }
   

1. 1. The value of Num is 10

   
   
   

   2. The value of Num is 100

   
   
   

   3. The value of Num is 1000

   
   
   

   4. Compilation Error

   
   
   

   5. None of these

       int main()
       {
           int num;
           cout << funOfSquare(num + 12);
           return 0;
       }
