A warning is exactly that; a warning. It's not a compilation error and your code does compile. It's simply warning you that you're assigning double values to integer variables, which will lead to truncation.

Yes. In particular, this line:
 
 
int gaji_bersih=total_gaji_kotor-(asuransi+pajak);


You're assigning the result of an operation involving doubles to an integer. If you change gaji_bersih to a double, you should be fine.

i cant change, if i use
int gaji_bersih=total_gaji_kotor-(asuransi+pajak);

will show Rp.1200000 (example show)

and if i use

double gaji_bersih=total_gaji_kotor-(asuransi+pajak);

will show Rp.12000e+006
