[help] PIC16F877A using for while problems

[sfchew7]

The design is I have 2 PARKING LOTS
if both of the inputs x and y = high
then z will show the number of parking lots now is : 0
Can someone teach me how to do this ?
I only know how to use the begineer method but don't know how to use
"For (z=0 ; z<3,z++ )" to complete the code
thanks

May be it will be helpful

z = 2;
while(1)
{
if(x & y)
{
z = 0; //parking lot full
}
else if( x & !y)
{
z = 1;
}
else if(!x & y)
{
z=1;
}
else
{
z = 2;
}
}

just a little optimization:
z = 2;
while(1)
{
if(x & y)
{
z = 0; //parking lot full
}
else if( x ^ y)
{
z = 1;
}
else
{
z = 2;
}
}

BTW: why not use a cheaper MCU like pic10f200 and assembly?

thank you for your help but my lectuere required me to use FOR WHILE, increment and decrements. if in VB I know how to do but this is c language , I have no ideas.
