### Compound Interest, varying rates

I am totally confused on how to write the formula for a compound interest. I thought that it would be A = P (1+r/n)^n+t, but the rates vary between each performance year and I wasn't taught how to do that in code. Please help.

 ``1234567891011121314151617181920212223242526272829303132333435`` ``````#include #include using namespace std; int main(void) { double Principal; double Perf1; double Perf2; double Perf3; double Perf4; double FinVal; cout.setf(ios::showpoint); cout.setf(ios::fixed); cout.precision(2); cout << "Please enter the initial amount invested: \$ "; cin >> Principal; cout << "Please enter the performance for year #1: % "; cin >> Perf1; cout << "Please enter the performance for year #2: % "; cin >> Perf2; cout << "Please enter the performance for year #3: % "; cin >> Perf3; cout << "Please enter the performance for year #4: % "; cin >> Perf4; FinVal = (1+ Perf4/1)^4; cout << "The final value of the stock is: \$ " << FinVal << endl << endl; return 0; } ``````
