Facing logical error. Need help to sort things up.

There is a code I made to calculate Simple and Compound interest. But whatever parameters I set for calculating compound interest, it always comes out to be zero. I went by the following approach: Amount = Principal + Interest Interest = Amount - Principal -------(1) Amount = Principal( 1+ Rate of interest/100)^(No.of years) ----------(2) { as the interest has to be compounded annually } So, interest comes out to be: C.I= P(1 + r/100)^(t) - P =>C.I= P[(1+ r/100)^(t) -1] Where did I go wrong? https://code.sololearn.com/cemoFnS5DV8i/?ref=app

Try using float instead of int

You probably entered to low values, I tried 10>>500>>2 and it worked. If values are too low it won't work, beacuse you divide it by 100.

Olek Szczepura It's not about big or small values. For example, if the principal amount is 100, the rate of interest is 10 and the time period is 2 years then the interest should be 21 but it's giving 30 as output
