Question

new file, invest.cpp 2. Prompt and read in the initial investment (type integer). 3. Prompt and read in the interest rate (type integer). 4. Prompt and read in the number of years (type double). 5. Compute the final value of the investment as: x*(1 + (R/100))' where x is the initial investment, R is the interest rate, and Y is the number of years. Use the C++ function pow to compute (1 + (R/100))'. Note that you will compute the investment value in years. 6. Compute the profit from the investment as: profit= (final investment) - (initial investment) 7. Output: Value of your investment compounded annually after Y year(s) is D dollars. Profit from your investment after Y year(s) is P dollars. where Y is the number of years, D is the final value of the investment, and is the profit. 8. Compute the final value of the investment continuously compounded as: where e is Euler's number and equal to 2.71828 9. Output: Value of your investment continuously compounded after Y year(s) is D' dollars. Profit from your investment after Y year(s) is p' dollars. The difference between both investment types is F dollars. where D' is the final value of the investment, P is the profit, and profits between both investment types. is the difference of the

solution：

Answer 1

#include<iostream>
#include<bits/stdc++.h>
using namespace std;
int main()
{
int ii;
float r,fi,y,profit,cc,temp;
cout<<"Enter initial investment (dollars):";
cin>>ii;
cout<<"Enter interest rate per year (percentage):";
cin>>r;
cout<<"Enter number of year:";
cin>>y;
fi=ii*pow((1+(r/100)),y);
cout<<"Value of your investment compound annually after "<<fi<<" dollars."<<endl;
cout<<"profit from your investment after "<<y<<" year is "<<fi-ii<<" dollars."<<endl;
temp = (r/100)*y;
cc=ii*pow(2.71828,temp);
cout<<"Value of your investment continuously compounded after "<<y<<" year(s) is "<<cc<<" dollars."<<endl;
cout<<"profit from your investment after "<<y<<" year is "<<cc-ii<<" dollars."<<endl;
cout<<"The difference between both investment types is "<<cc-ii<<" dollars.";
}

Output :--

Enter initial investment (dollars):1000
Enter interest rate per year (percentage):1.2
Enter number of year:2
Value of your investment compound annually after 1024.14 dollars.
profit from your investment after 2 year is 24.1439 dollars.
Value of your investment continuously compounded after 2 year(s) is 1024.29 dollars.
profit from your investment after 2 year is 24.2903 dollars.
The difference between both investment types is 24.2903 dollars.
