void main()
{
int a,b;
b=1;
if(a=b);
else
a=2;
a=3;
printf(�%d \t%d �,a,b);
while(b<3)
a+=++b;
printf(�\n %d \t %d�,a,b);
}
What�s the output? Can you answer it ? or it�ll make error?
It�ll successfully run without compilation errors.
Output:
3 1
8 3
How?
At first b=1
As per I said before , it can possible to assign value for variables in if and also if can end with semicolon
if(a=b);
is equivalent to
if(a=b)
{
}
Now a =1
if(a=b) i.e. if(1)
so it won�t go to else part.
So a=3
In while b<3
a+=++b is equivalent to a=a+(++b)
at first b=1 ,a=3
1<3 true so a=3+(2)=5 ,b=2
2<3 true so a=5+(3)=8, b=3
3<3 false
Now a=8 b=3
