Answer:
Follows are the code to this question:
#include<iostream>//defining the header file
#include<cmath>//defining the header file
using namespace std;
int main() //defining main method
{
double p,a,r;//defining double variable
int n,t;//defining integer variable
bool flag = true;//defining bool variable flag
while(flag) //defining while loop for input value
{
cout<<"Enter Present Worth: ";//print message
cin>>p;//input value in p
cout<<"Enter number of compounding: ";//print message
cin>>n;//input value in n
cout<<"Enter Loan Period: ";//print message
cin>>t;//input value in t
if (p<10000)//defining if block that check principle value is graeter then 10000
{
r = 0.02;//defining r varaible that store 0.02 value
}
else if (p>=10000 && p<=50000)//defining else if that value of p is in 10000 to 50000
{
r = 0.05;//defining r varaible that store 0.05 value
}
else if (p>50000)//defining else if that value of p is in 50000
{
r = 0.07;//defining r varaible that store 0.07 value
}
a = p*pow((1 + r/((double)n)), n*t);//defining formula for calculate A
cout<<"\nInterest Rate of Loan: "<<r<<endl;//print r rate value
cout<<"Future Worth: $"<<a<<endl;//print A value
cout<<"Total Interest: $"<<(a-p)<<endl<<endl;//print total interest value
char c;//defining char variable c
cout<<"Do you want to check for more loans(Press 'Y' for yes, otherwise press any other key): ";//print message
cin>>c;//input char value
if (c!= 'Y' && c!= 'y')//define if block that check c value is not equal to y
flag = false;//use flag that hold value false
}
cout<<"Thank you!!!"<<endl;//print message
return 0;
}
Output:
please find the attched file.
Explanation:
In the code, inside the main method three double variables "p, a, and, r", two integer variable "n and t", a bool variable is defined, in which double variable "p, n, and t" is used to input the value from the user-end.
