//Declared test cases
    float principal = 200000.00, annualInt = 0.03;
    float years = 10.0;

float calcInterest1(float principal, float years, float annualInt)
{
    float interest1;
    float nt = annualInt*12;
    float A = principal+annualInt;//Accrued Amount
    interest1 = (A = (principal*(1+years/100))pow(nt));// A = P(1 + r/n)nt
    return interest1;
}
