Question

hello I am working in a c++ problem and my answers should have decimals but when I compiled run the program it does not show any decimals

Answer 1

If you perform integer division then you get integer results only.
For example
int i = 5, j = 2;
then if you ptint
cout<<(i/j)<<endl;
Then it prints 2 instead of 2.5.

So, If you want result in decimal then just multiply expression with 1.0.
For example
cout<<(1.0*i/j)<<endl;
This prints in decimal value 2.5

Or you can also cast the result to float.
For example
cout<<((double)i/j)<<endl;
This also prints in decimal value 2.5
