Answer 1

#include<iostream>

#include <math.h>

using namespace std;

int main()

{

int ch;

float A , P , r , n;

cout<<"Press 1 for Term deposit \nPress 2 for Recurring deposit \nEnter your choice : ";

cin>>ch;

switch(ch)

{

 case 1:

  cout<<"Enter Principle : ";

  cin>>P;

  cout<<"Enter Rate of Interest : ";

  cin>>r;

  cout<<"Enter Time Period in years : ";

  cin>>n;

  A=P * pow((1 + r / 100.0),n);

  cout<<"Maturity Amount : "<<A;

  break;

 case 2:

  cout<<"E n t e r M o n t h l y I n s t a l m e n t : ";

  cin>>P;

  cout<<"Enter Rate of Interest : ";

  cin>>r;

  cout<<"Enter Time Period in months : ";

  cin>>n;

  A = P * n + (n * (n + 1) / 2.0) * r / 100.0 * 1.0 / 12.0;

  cout<<"Maturity Amount : "<<A;

  break;

 default :

  cout<<"Incorrect Option";

}

return 0;
