write a c++ program that reads an integer that represents the amount of money in NIS. And read a character that represents the type of currency you want to convert to. For example: - 'J' for JD, 'D' for dollar and 'E' for Euro. Then you program should convert the input amount of money to the corresponding currency by using the switch selection structure.
Hint

currency	Amount in NIS
JD	5.3
Euro	5.5
US dollar	3.7

Try:

#include
#include
#include

using namespace std;

int main()
{
int amount;
char type;

cout << "Enter amount in NIS : ";
cin >> amount;

cout << "Enter first letter of currency to convert to J(D), D(ollar), E(uro) : ";
cin >> type;

type = toupper(type);
cout.setf(ios::fixed);
cout.precision(2); // limit to 2 d.p.

switch (type)
{
case 'J':
cout << "This converts to "<< (double)amount/5.3 << " JD";
break;

case 'D':
cout << "This converts to "<< (double)amount/3.7 << " US Dollars";
break;

case 'E':
cout << "This converts to "<< (double)amount/5.5 << " Euros";
break;

default :
cout << "Invalid currency type";
break;
}

return 0;
}

you can use getch statement at the end of your program to pause the window..

If you're running in debug mode under VS, I'd make the highlighted changes to stop the console window from closing until you press a key:

#include
#include
#include
#include

using namespace std;

int main()
{
int amount;
char type;

cout << "Enter amount in NIS : ";
cin >> amount;

cout << "Enter first letter of currency to convert to J(D), D(ollar), E(uro) : ";
cin >> type;

type = toupper(type);
cout.setf(ios::fixed);
cout.precision(2); // limit to 2 d.p.

switch (type)
{
case 'J':
cout << "This converts to "<< (double)amount/5.3 << " JD";
break;

case 'D':
cout << "This converts to "<< (double)amount/3.7 << " US Dollars";
break;

case 'E':
cout << "This converts to "<< (double)amount/5.5 << " Euros";
break;

default :
cout << "Invalid currency type";
break;
}

cout << endl;
system("pause");
return 0;
}
