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;
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;
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 explain this to me.
