Help with restarting a program

[vincent dominguez]

Hello today I wanted to make a simple calculator and understand how it works
and here's what I got so far but I can't get it to restart itself when I press
one key.

The Code so far is :

include <iostream>

using namespace std;

int main()
{
char rept;
do
{

int a;

int b;

int sum;

cin >> a;

cin >> b;

sum = a*b;

cout << "Awnser: " << sum << endl;

cout << "The answer is solved by Vincent Dominguez your awnser correct. "<<
endl;

cin >> rept;

while (rept == 'y' || rept == 'Y');
return 0;
}

Then I get a error at the } end.
can someone tell me how to fix this and explain it to me thanks.

Just do what compiler says to you. You missed an }. you must to find out
where.. Its really easy to find it. I'm not going to tell you... I just tell
you that if you open an { some where you must close it with an }

One trick to help you avoid this kind of errors is to write your code like
this

#include <iostream>
#include <cstdlib> //windows OS

using namespace std;

int main(void)
{
   int a, b, sum;
   cin >> a;
   cin >> b;
   sum = a + b;

   if(sum >= 0)
   {
      cout << "Sum>= 0" << endl;
   }
   else
   {
      cout << "Sum <  0" << endl;
   }

   system("pause");  //windows OS
   return 0;  
}

Its better to use mean full variables like: sum = a + b and product = a * b.
In programs like this its not easy to notice how much useful is, but in a
program of 2000 lines (a student program) is very useful.
