Hey guys, im just learning C++ and i really want to learn it, but im having some compiling errors and i've looked around and i dont know what else to do. So i was hoping one of you guys could help me out.

so this is my code:

#include <iostream>

int main()
{
   int integer1, integer2, sum;

   std::cout << "Enter first integer\n";
   std::cin >> integer1;
   std::cout << "Enter second integer\n";
   std::cin >> integer2;
   sum = integer1 + integer2
   std::cout << "Sum is " << sum << std::endl;

   return 0;
}

Its pretty simple enough, and i know what its supposed to do, but its not becuase its not compiling.

These are the errors i get when i compile and try to run the file:

c:\users\bioshock\documents\c++\untitled1.cpp: In function `int main()':
c:\users\bioshock\documents\c++\untitled1.cpp:12: use of namespace `std' as expression
c:\users\bioshock\documents\c++\untitled1.cpp:12: parse error before `::'

Im not really sure what that meant, so any help would be nice.

Thanks.

try removing all the std keywords before cin and cout.. tell if it works..

Having the thread in the right forum helps. Moved to C-C++ forum

put the semicolon
sum = integer1 + integer2;

[debleena_doll2002]

first sol :

#include <iostream.h>
int main()
{
   int integer1, integer2, sum;

   cout << "Enter first integer\n";
   cin >> integer1;
   cout << "Enter second integer\n";
   cin >> integer2;
   sum = integer1 + integer2;
   cout<<"Sum is " <<sum<< endl;
   return 0;
}

second solution:

#include <iostream>
using namespace std;

int main()
{
   int integer1, integer2, sum;

   std::cout << "Enter first integer\n";
   std::cin >> integer1;
   std::cout << "Enter second integer\n";
   std::cin >> integer2;
   sum = integer1 + integer2;
   std::cout<< "Sum is " << sum << endl;
   return 0;
}

Oh thanks for the reply's and sorry about having it in the wrong section. I put it in there becuase i thought you couldnt ask questions in the regular programming sections.

You are not suppose to use iostream.h in C++. If you dont want to use std:: again and again then this would be a better solutio

using std::cout;
using std::endl;

your statement std::cout << "Enter first integer\n"; is wrong. Because the keyword ::
is the scope resolution key word. here is incorrect.
you should remove it from here.

Please dont spread wrong information. First :: is not a keyword it is a scope resolution operator. Second first verify your post with any good C++ compiler, if you dont have access to any then check your code with online C++ compiler from here

http://www.comeaucomputing.com/tryitout/

And here is from latest draft of C++ standard

Section 3.3.5.2

Quote:

A namespace member can also be referred to after the :: scope resolution operator (5.1) applied to the name of its namespace or the name of a namespace which nominates the member’s namespace in a using-directive;
see 3.4.3.2.

yes, you are right zamjad. I have write it by mistake. Yes it is not keyword it is scope resolution operator.
sorry for that mistake.
