Doubt in suffix for a variable

[Murugesh_89]

Hi,
Please let me know the reason..

My program is...

void main()
{
int a,b;

a = -1;
b = -1u;

if(a == b) do_task1;
else do_task2;
}

The condition passes and do the task1. Why is it so even though i made b as unsigned??

Need reason for this...

You have declared a and b as int variables?

 int a,b;

 Change it to unsigned int a , b;

and see if you get the right value.
