My country Ghana is changing its currency. I want to write a small

Please any suggestion is welcome :)
Frankly, it sounds like homework. Google, "Ghana currency converter" and
you will find dozens of them.
The following is what I have been able to do so far:
#include <iostream>
using namespace std;
int main(){
//variables declared
int old_currency_value, new_currency_value, result_of_formula;
//questions to ask user
cout<< "Please enter the value of the old currency you wish to
convert";
cin >> old_currency_value;
//conversion implementation
new_currency_value = old_currency_value/10000;
cout << "The value of the new currency is " << new_currency_value <<
endl;
//quit programme
return 0;
Your missing the close paren at the end, otherwise your program will
compile and run. Is the output what you expected?
This is no joke Daniel T :).My country is CHANGING its currency. I'm
not looking for some fancy converters from the old Ghana cedi to US
dollars and other currencies. I'm looking to write my own programme
that can convert from the old Ghana cedi to the NEW Ghana cedi, and I
intend to do just that with C++. Thanks for the tip about closing
parentheses. It is well noted. Please more suggestions are welcome.
The source code now looks like this:
Looks quite good, there is one problem though, if I input 5000 and
500000 I get the same result (50) because you don't tell the user the
type of the answer.
Also notice that the variable result_of_formula is never used so you can
delete it. You can also, if you wish, get rid of the variables
new_currency_value and value_in_pessewas by performing the calculations
in the if-statement, like this:
#include <iostream>
using namespace std;
int main() {
double old;
cout << "Please enter the value of the old currency"
"you wish to convert" << endl;
cin >> old;
if (old < 10000) {
cout << "The value of the new currency is "
<< old / 100 << " pessewas" << endl;
}
else {
cout << "The value if the new currency is "
<< old / 10000 << " cedi" << endl;
}
return 0;
}
