Multiline Macro

[saswatdash83]

Hi All,

I want to implement a macro which will toggle a bit in a byte.The user will give input from keyboard.

toggle(number,bit to be toggled)
Number,bit to be toggled will be input from keyboard.

eg:-suppose user want to toggle 2nd bit of a 8 bit number 10010011.

Then have to implement the macro toggle(10010011 , 2)

Wrtite the code to do this and then convert it to a macro.

I assume you are coding C because C++ uses a bitset object for this.

yes I'm coding C.I don't know the syntax for multiline macro.

Could anybody write the code systematically.

Here you go. Use the \ as the continuation character.

#define DOIT(x,y) int z = x + y;\
printf("%d\n", z);

int main()
{
DOIT(3,4);
}
