How do you exchange or swap TWO (2) variables A and B with using a
third or temporary variable?

C program (Attach TWO (2) sample output for each program)

JUST SHOW ME 2 EXAMPLE OF C PROGRAM

simple, here is a algo & please code the program yourself

let a=5
b=6
a=a+b
b=a-b
a=a-b
now a=6 and b=5

another homework..

Why're you making a new thread for this? Post it in that thread you've already created about C...

You are seriously asking how to swap with a temporary variable and not without?

^^guess not

In that case,
x=a;
a=b;
b=x;

PS: Makes me feel like a genius coder.

another homework obviously.

Maybe we should create a separate thread: "Post all your homework questions here" :lol:

Only if you pay me for it

a=a^b;
b=a^b;
a=a^b;

a=a^b;
b=a^b;
a=a^b;

won't "+" or "-" operators suffice ?? I think they are less expensive than "^" ...

How's addition and subtraction less expensive than an XOR? You've learned your computer architecture properly, haven't you Garbage?

It would result in more gate delays than a simple xor.

I thought he meant "raise to"

thought it's algorithm than statements...

yep, Bitwise operations are fastest.

but this things are never taught in our education system
what we learn is using a two and a half decade old program called "TC"

a thread named "HOMEWORK HELP" must started

This will save space + other's problems can be reviewed without having to use the search engine

dont u think the question deserved no more than 2 posts.. (this applies to me also for posting this useless post)
