I'm trying to make a program which will give the interest of a capital that is invested.
Can anyone tell me what type I have to use to define a result so it only shows 2 decimal points?
Thanks!

You can use either float or double, but when printing the output, you must define the precision. For example,
printf("Interest: %9.2f\n", myInterest);

If I remember correctly you can use either double or float. When you are printing you have to format output like this
printf("Interest is %2d dollars.",variable_interest);
This %2d will ensure that it shows only 2 decimal points.

You should use the 'float' data type.
