He knows the interest rate R (an integer between 0 and 20) that is compounded annually at his bank. He has an integer amount of money M in the range 100..1,000,000. He knows how many years Y (range: 0..400) he intends to invest the money in the bank. Help him learn how much money he will have in the future by compounding the interest for each year he saves. Print an integer answer without rounding. Answers for the test data are guaranteed to fit into a signed 32 bit integer. 输入描述 * Line 1: Three space-separated integers: R, M, and Y 输出描述 * Line 1: A single integer that is the number of dollars FJ will have after Y years. 样例输入 5 5000 4 样例输出 6077 来源 USACO 2004 November Gold 提示 INPUT DETAILS:

题记：程序做多了，不定哪天遇见似曾相识的。

AC的C++程序如下：

/* POJ2390 Bank Interest */#include <iostream> #include <cmath>using namespace std;int main() {int r, m, y;cin >> r >> m >> y;cout << (int)(m * pow(1 + r / 100.0, y)) << endl;return 0; }
