C language problem
Hi. I have a few problems which really confuse me and I would appreciate it if you can help me out! Thank you!
1) How can I set Port C bits 0,5 and 7 and clear all other bits in a C statement?
2) Give a C statement that will configure Port C with the highest 3 bits as inputs and the other bits as outputs.
3) What type of logic gate is used to select the rising or falling edge of a clocking signal?

What have you tried thus far? Note that most of your questions are actually not concerning C, e.g., you need to read your notes or the relevant manual.

really? I'm supposed to use a program named microchip

Do you know anything about bits?
BitPos 76543210
BitVal 10100001
As for setting port C, you'd have to read your compiler / development environment / processor manual.
It could be anything like these, or any variation on the same theme.
PORTC = value;
setport(PORTC,value);
setPortC(value);
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
Find out what chip and find the Manual for that chip or chip family.

1)Buddy.
Your question is related embedded C.
First of all search for your chip's reference manual.
Then what compiler software you are using.
Basically it is like,
PORTC=0Xb10100001(if your port is 8 bit)
Otherwise it depends on your compiler and chip.
3) see how to select the rising and falling edge of a clock is generally mentioned in reference manual of chip.
What is "Port C"?
Title of this post is bad, there is no "problem with C language".
Sounds like a very hardware-specific question, with a misleading title.
