Question { Burning Glass, 14246 }

#include
#include
# define swap(a,b) temp=a; a=b; b=temp;
void main( )
{
int i, j, temp;
i=5;
j=10;
temp=0;
if( i > j)
swap( i, j );
printf( "%d %d %d", i, j, temp);
}

Answer

my dear frd....
here some hapen.
#define swap(a,b) temp=a;a=b;b=temp;----------(1)
is was as function of swap two no;(but it is differnt frm
funtion.)
so
at i>j;
enter swap(i,j);
so jump at eq(n) ---(1) and call swap function'
and


temp=5;


i=10;
j=0;

you see three variable.
but it printf i,j to convert swap.
bcoz it have two arguments.
and print temp=0;
becoz temp have 0;
