I have just started with a tutorial in c++ and i wonder if anyone can tell me what´s wrong with this code

#include <iostream>

using namespace std; //so the program can see cout and end1

int main()
{
        
          for  (int x = 0; x < 10; x++) {
              
               cout<< x <<end1;
               }
              cin.get();
}

This thread shows a classic beginner case: posted a short C++ example and it was fixed quickly by and . A few concise follow-up tips that help avoid similar traps and make debugging easier are listed below.

Always compile with warnings enabled so small mistakes surface immediately. A common g++ command is g++ -Wall -Wextra -std=c++17 file.cpp -o program; GCC documents its warning options at GCC warning options. Exact compiler output and the command line used are the most useful information when diagnosing problems.

Be aware that some I/O manipulators also cause a stream flush, which affects performance and observable behavior; pick the right manipulator when a flush is intended. See the standard description of std::endl for details: std::endl. The C++ language rules about the main function and its return behavior are documented here: .

For larger projects, avoid using namespace std in headers or shared code; prefer explicit std:: qualifiers for clarity and to prevent name collisions (namespace FAQ). For simple pauses during learning, running the program from a terminal or using the debugger is usually more robust than ad hoc input reads. Troubleshooting is fastest when exact compiler messages and the build command are included.

Posting error messages helps.

> end1;
In your case, I guess you mean endl
That's lower-case "L" (l) at the end, not numeric one(1).

Use return 0; at the end of the program, otherwise compiler will throw warning.
Its a good programming practice.
