Hi guys! Good day!
I'm a student in computer science and currently practicing basic c++ lesson,
I need help for my project that will be pass on December 11,2018 in the morning. It is all about login and signup program.

This is my code:

#include <iostream>
using namespace std;

int a,b,choice1;

int addition(int a, int b)
{
cout <<" Addition" << endl;
cout <<" Enter 1st number: ";
cin>>a;
cout <<" Enter 2nd number: ";
cin>>b;
cout <<" The sum is " << a+b << "." << endl;
}

int subtraction(int a, int b)
{
cout <<" Subtraction" << endl;
cout <<" Enter 1st number: ";
cin>>a;
cout <<" Enter 2nd number: ";
cin>>b;
cout <<" The difference is " << a-b << "." << endl;
}

int multiplication(int a, int b)
{
cout <<" Multiplication" << endl;
cout <<" Enter 1st number: ";
cin>>a;
cout <<" Enter 2nd number: "
