mathematical porgram

[nik88]

ive written this program in turbo C++ but when i try to run it in Visual Studio it says that i have a fatal error: C1083. here is my program


#include <iostream.h>
#include <stdlib.h>
#include <conio.h>


short i, ctr;
short score=0;
short num1, num1, ans;

void add() {
cout << "\n";
randomize ();
num1 = (rand () % 100) + 1;
num2 = (rand () % 100) + 1;
do {
cout << num1 << " + " << num2 << " = ";
cin >> ans;
ctr++;
}while ((ans!=(num1+num2)) && ctr<3);

switch (ctr) {
case 1 : cout << "correct! \n\n"; score += 10; break;
case 2 : cout << "correct! \n\n"; score += 5; break;
case 3 : cout << "correct! \n\n"; score += 2; break;
default : cout << "wrong! the answer was " << num1+num2 << "\n\n";break;
}
}

void subt() {
cout << "\n";
randomize ();
num1 = (rand () % 100) + 1;
num2 = (rand () % 100) + 1;
do {
cout <<num1 << " - " << num2 << "=";
cin >> ans;
ctr++;
}while ((ans!= (num1-num2)) && ctr<3);

switch (ctr) {
case 1 : cout << "correct! \n\n"; score += 10; break;
case 2 : cout << "correct! \n\n"; score += 5; break;
case 3 : cout << "correct! \n\n"; score += 2; break;
default : cout << "wrong! the answer was " << num1-num2 << "\n\n";break;
}
}

void mult() {
cout << "\n";
randomize ();
num1 = (rand () % 100) + 1;
num2 = (rand () % 100) + 1;
do {
cout <<num1 << " * " << num2 << "=";
cin >> ans;
ctr++;
}while ((ans!= (num1*num2)) && ctr<3);

switch (ctr) {
case 1 : cout << "correct! \n\n"; score += 10; break;
case 2 : cout << "correct! \n\n"; score += 5; break;
case 3 : cout << "correct! \n\n"; score += 2; break;
default : cout << "wrong! the answer was " << num1*num2 << "\n\n";break;
}
}

void main () {
char choice;
do {
cout << "Please choose one of the following. (score: "<< score <<")";
cout << "0. exit, 1. add, 2. sub, 3. mult";
choice = getch()

ctr = 0;
switch (choice) {
case '1': add (); break;
case '2': subt (); break;
case '3': mult(); break;
}
}while (choice!= '0');
}

This is the Visual BASIC, not Visual Studio in general section.

What version do you have? VC++ probably doesn't have conio.h (which is Turbo-C specific), and it works differently too. If you don't know these things, or the differences, etc, then you shouldn't be doing it.
