	double b=a/1000;
	
	printf("&#37;d",b); //123.456 output wanted
}

Do help..

Two mistakes:
1. dividing two integers gives an integer answer. You want a floating point answer, so you need to make sure at least one of the numbers is floating point e.g. 1000.0
2. %d is the wrong format specifier for a double. Read your documentation again to find the correct specifier.

2. %d is the wrong format specifier for a double. Read your documentation again to find the correct specifier.

It's %f, not %lf, which you might expect.

Also consider returning 0.
