The Forex exchange system deal with the currency of the different countries and here is the complete code of this system in C++. The Forex exchange system consist of 4 major modules and these are admin,user,signup,and visitors modules. The admin module deal with the currency rates,currency sold and about system information. The user module deal with the customers who already have account on the system and signup module is for new customers to join the system.
