C Questions and C++ questions

    c/c++ section:  questions on c/c++, programs o/p 
etc.                                



 1    main( )
       {
        unsigned int i=3;   
        while( i >=0)
        printf( "%d", i--);
       }
     how many times will the printf stmt be executed?
     a)0     b)3     c)4     d)infinite
     Ans: I think the answer is infinite, b'cos 'i' is an 
unsigned integer and it will not 
     decrement below '0' and hence end up in an infinite 
loop.(yes, i checked and it 
     is getting stuck in an infinite loop)

2.   main( )
       {
        int x,y, z;
        x=2;
        y=5;
        z= x+++y;
        printf("%d %d %d", x, y z);
       }
      a)3 5 7 b)option 2 c)option 3 d)option 4
      Ans: a

3    # define swap(a,b) temp=a; a=b; b=temp;
      main( )
       { 
        int i, j, temp;
        i=5;
        j=10;
        temp=0;
        if( i > j)
        swap( i, j );
        printf( "%d %d %d", i, j, temp);
      }
     Ans: On compiling i got ans 10, 0, 0. I did not 
understand the concept. Please
     expalin this to me.

4.  Java section: questions on java related stuff.
     1) Java was initially code named as:
     a)Oak b)green c)miller d)option4

3    # define swap(a,b) temp=a; a=b; b=temp;
      main( )
       { 
        int i, j, temp;
        i=5;
        j=10;
        temp=0;
        if( i > j)
        swap( i, j );
        printf( "%d %d %d", i, j, temp);
      }
     Ans: On compiling i got ans 10, 0, 0. I did not 
understand the concept. Please
     expalin this to me.
its because macro is expanded as

      temp = i;
      i =  j;
      j = temp;

the condition gets false as i < j and first statement i.e. 
temp = a is not executed and remaining  statements gets 
executed and results in i = 10 and j = 0.
