You wrote 'void main()' which results in undefined behaviour.

kind regards,

You wrote 'void main()' which results in undefined behaviour.

Also he forgot code tags, that is by an order of magnitude larger sin.
And let alone printf("%d%d",&b,b) where &b is printing b's address ( if pointer and int are both 32 bit).

[donbock]

printf("%d%d",&b,b);

}

This format string is incompatible with the arguments: %d is for printing an int; &b is a pointer, b is an int.
Why would you want to print two numbers without any space between them?

The OP also didn't write his/her post in English; as a non-native speaker I had to
guess for the meaning of 'wats d op of this program... pls get soon..'.

My crappy-post-o-meter is rising ;-)

actually i wanted print both address and value of b ,

If you want to see what it outputs, I recommend compiling and running this code. For the code itself, I recommend printing the address in hexadecimal and add some whitespace in between the two numbers so you can tell them apart.

"%p" is preferred for printing the address of a variable.
