btw, i am on a mac computer at school, and have the coding on a floppy. mac isnt lettin me copy n' paste, so i cant do the code]....[/code] statement. srry... and disregard those squares at the start of each line...macs are so dumb!

Code:

#pragma hdrstop

#include <iostream.h>

#include <conio.h>



void main()

{



int var1

int var2

int var3

int var4

int choice1

int choice2

int Answer1

int Answer2

    

   do

    {

    cout << "\nHello, do you want to add or subtract numbers? (a/s)";

    cin >> choice1;

    

      if ( choice1 == 'a' )

        {

        cout << "\nPlease enter the first number and second number, to be added, seperated by a space: ";

        cin >> var1;

        cin >> var2;

        

        Answer1 = var1 + var2

        

         cout << "\nThe answer is " << Answer1;

        }

        

      if ( choice1 == 's' )

        {

        cout << "\nPlease enter the first number and second number, to be subtracted, seperated by a space: ";

        cin >> var3;

        cin >> var4;

        

        Answer2 = var3 + var4

        

         cout << "\nThe answer is " << Answer2;

        }

      

        cout << "\nDo you want to do this again? (y/n)";

        cin >> choice2;

        

    }  

    while ( choice2 != 'n' )

    getch()

    

}

liek whcih ones? if doesnt need it, i think. and errors i get are like cout undeclared and var1 undeclared ....errors like that.

void main()

shouldn't that be

Code:

 int main(void)

can u guys actually tell me where i am wrong? i did notice i forgot the ; after the parts where i was asigning the values for the asnwer1 and 2 variables. ill put those in when i get to my house. where else is sumthin wrong? do i need iostream.h, or iostream? and ill also try the int main(void) command when i get home. thx for ur help so far!

im not big on c++ but i think it should be

Code:

#include <iostream>
using namespace std

hmmm....ok, i will try that for the header.

ok, i will try this stuff when i get home. thx alot, ill post back if it dont work.
