Q. # 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.
 
And...the answer fot ur question is first preprocessor will modify ur code before compilation...so the #define swap will be substituted in the line no.6 of the  main...so ur code will become like this before compilation...  

line 1: int i, j, temp;
line 2: i=5;
line 3: j=10;
line 4: temp=0;
line 5: if( i . j)
line 6: swap( i, j );
line 7: printf( "%d %d %d", i, j, temp);
Because of preprocessor, line 6 becomes
 temp=i; i=j; j=temp;
so...this is equivalent to
temp=i;
i=j;
j=temp;
 hence...ur overall main becomes
 int i, j, temp;
i=5;
j=10;
temp=0;
if( i . j)
temp=i;
i=j;
j=temp;
printf( "%d %d %d", i, j, temp);
 and...now i think u will know why the answer was 10, 0, 0 ..
