142. What is the difference between the following 2 codes?
     

     //Program 1
     #include <stdio.h> 
         int main()
         {
             int n3, n1 = 2, n2 = 3;
             n3 =  n1++ + ++n2;
             printf("%d %d %d", n3, n1, n2);
         }
     

     
     

     //Program 2
     #include <stdio.h> 
         int main()
         {
             int n3, n1 = 2, n2 = 3;
             n3 =  n1++ + +++n2;
             printf("%d %d %d", n3, n1, n2);
         }
     

1. 1. Space does make a difference, values of n1, n2, n3 are different

   
   
   

   2. No difference as space doesn’t make any difference, values of n1, n2, n3 are same in both the case

   
   
   

   3. Program 2 has syntax error, program 1 is not
