Question

I need a c++ program that converts U.S dollar amount to Zambian Kwacha, Belize, and Hong Kong dollars. I have the following code, but its not working corrrectly.

#include<iostream>

#include<iomanip>

using namespace std;

int main()

{

const double ZAMBIANKWACHA_PER_DOLLAR = 9950;

const double BELIZE_PER_DOLLAR = 2.10;

const double HONG_KONG_PER_DOLLAR = 7.76;

double dollars, zambiankwacha, belize, hongkong;

cout << setprecision(2) << fixed;

cout << "Enter dollar amount: ";

cin >> dollars;

zambiankwacha = dollars * ZAMBIANKWACHA_PER_DOLLAR;

belize = dollars * BELIZE_PER_DOLLAR;

hongkong = dollars * HONG_KONG_PER_DOLLAR;

cout << "-------Conversion------- ";

cout << "$" << dollars << " = " << zambiankwacha << " zambiankwacha ";

cout << "$" << dollars << " = " << belize << " belize ";

cout << "$" << dollars << " = " << hongkong << "Hong Kong " ;

system("pause");

return 0;

}

Explanation / Answer

Simply, remove system("pause") from the program and it will run:

#include<iostream>

#include<iomanip>

using namespace std;

int main()

{

const double ZAMBIANKWACHA_PER_DOLLAR = 9950;

const double BELIZE_PER_DOLLAR = 2.10;

const double HONG_KONG_PER_DOLLAR = 7.76;

double dollars, zambiankwacha, belize, hongkong;

cout << setprecision(2) << fixed;

cout << "Enter dollar amount: ";

cin >> dollars;

zambiankwacha = dollars * ZAMBIANKWACHA_PER_DOLLAR;

belize = dollars * BELIZE_PER_DOLLAR;

hongkong = dollars * HONG_KONG_PER_DOLLAR;

cout << "-------Conversion------- ";

cout << "$" << dollars << " = " << zambiankwacha << " zambiankwacha ";

cout << "$" << dollars << " = " << belize << " belize ";

cout << "$" << dollars << " = " << hongkong << "Hong Kong " ;

return 0;

}

Reason:

system("pause") is generally used by learning programmers to pause the system, so that the programmers can read their output.
system("pause") runs windows command-line "pause" and wait for programmers input to execute the program further.
Good way to do is run the program in debug mode, and put a breakpoint at the end of the program.

So, it is a platform specific thing, and should be used only in windows. There might be possibilities that it runs on other platforms, but in those IDE(s) which supports virtualization.
