CODE HELP!!!

[yogurt]

ok, after almost finishing my first usable program. I started to debug and i got a couple of errors which i cant fix. This is my code and the errors are at the bottom. Thanx ;)

#include<iostream.h>
using namespace std;
int main() {
     char loop = 'y';
     char operand;
     float f1;
     float f2;
     float f3;
     system("TITLE Calculator V2.01");
     system("COLOR 2");
     
     do while(loop == 'y' || loop == 'Y')
     {     
           system("CLS");
           cout <<" Welcome to Calculator Program V2" << endl;
           cout << " Please type in your first integer or decimal: "; 
           cin >> f1;
           cout << " Now select a operation you wish to complete(-,+,*, or /): ";
           cin >> operand;
           cout << " Finally, type in your last integer or decimal: ";
           cin >> f2;
           cout << endl << endl;
           
           switch(operand)
           {              
                          case '+' :
                               f3 == f1 + f2;
                               cout << "The answer is " << f3 << endl;
                               cout << f1 << "+" << f2 << "=" << f3 << endl;

Try changing
#include<iostream.h>
to

#include<iostream> 

and

     do while(loop == 'y' || loop == 'Y')
     {
...
     }
     cout << "Would you like to start again? [y/n]: ";
     cin >> loop;
...

to

     do 
     {
...
           cout << "Would you like to start again? [y/n]: ";
           cin >> loop;
     } while(loop == 'y' || loop == 'Y')

i changed iostream

do ...code... while and do while just differently placed. I think its something else

i did it anyways same think cept the header error is gone

You have a closing brace '}' missing.

Also you are using '==' insdead of '=' in your case statments
f3 == f1 + f2; should be
f3 = f1 + f2;

there may be other errors.

ok thanks it waorks now. that alst post fixed it but what does
#include<stdlib.h>

from apperent noob lol(i am though 2nd day programming)

[z05DSL3A]

#include <stdlib.h> (should really have been #include <cstdlib>) in there to allow the system() function.
