Can't compile and execute console application Code Blocks

Question

I have used Code blocks IDE for about a week now, and all worked fine until yesterday when I tried to build this code:

#include <iostream>

using namespace std;

int main()
{
  int sum = 0 , value = 0;

  while(cin >> value){
    sum += value;

    cout << "summen er: " << endl;
    cout << sum <<endl;
  }
  return 0;
}

Which resulted in the following build log:

(x86)/codeblocks/mingw/bin/../lib/gcc/mingw32/4.7.1/../../../../mingw32/bin/ld.exe: cannot open output file bin\Debug\While_input.exe: Permission denied

collect2.exe: error: ld returned 1 exit status

Process terminated with status 1 (0 minute(s), 0 second(s))
1 error(s), 0 warning(s) (0 minute(s), 0 second(s))

I can no longer compile and run any code neither older projects which earlier this week worked fine.

I googled the problem and tried the following solutions:

run Code Blocks as admin
switch of Firewall
re install Code blocks
use task manager to see whether my application was still running.

So far nothing has worked. Does anyone know how I can fix this?

And you don't have the program already running and lingering in the background? — Some programmer dude
No it is not. yeah there is no while_input.exe file in the project folder. — user2987949
On Windows, you can't overwrite a program that is already running. That means you can't build if it's running, because then you get the error you have. You should look in the task-manager to see if it's running, and if it is then kill it. — Some programmer dude
but the problem is that it isn't as far as I can tell running. — user2987949

This program works well in my computer.

There is no prompt for input in your program. The program when run in C++ mode shows a cursor. Enter a simple number and enter, it just reproduces the value.
Code blocks sometimes saves files as default in C rather than CPP. Have you tried saving as .cpp? John
