I had the exact same problem (I am also a beginner). You'll want to wewrite the code like this:

Code:

---

#include <stdio.h>
int main()
{
      {printf("hello");
      getchar();
      }
}

---

So, what exactly are you adding in? Well, the getchar(); statement is telling the program (when executed) that it needs to stay open instead of just executing and closing. If you don't have the getchar(); in there, the program will close without allowing ample time to read what's on the screen (i.e. viewing data), enter in data, etc.

Note to advanced C programmers: If I'm wrong about what the getchar(); statement does, please help me better understand my own programming by telling me. Thanks.

why are you using the red ones?

Code:

---

#include <stdio.h>
int main()
{
      {printf("hello");
      getchar();
      }
}

---

getchar just waits for an input, it reads one character from the input-stream stdio.
with

Code:

---

#include <stdio.h>
int main()
{
      char c;
      printf("hello");
      c = getchar();
}

---

you could use the pressed key.

you could also use system("pause"); to stop the programm while executing.

mfg

Code:

---

system("pause")

---

Calls to the system = bad.

Read the FAQs link that itsme86 posted.

You can also run your program by going to the command prompt and typing in it's name and the command prompt won't close.
Console programs aren't realy designed to be double clicked which is why they close.

You had a few errors in the code. I corrected them for you.

1.You did'nt declear your main function as an int.
2.You left out "\n" it still compiles even if you leave it out but the screen is clearly presented if you put it in.

helloPress any key to continue(if you don'nt use \n)

hello
Press any key to continue(if you use \n)

3.Your program was'nt returning anything always put (return 0) if you don'nt want it to return anything.
4.Last thing was that you did'nt put the end braces. If you open a brace you always have to close it.

Code:

---


#include <stdio.h>
int main()
{
        printf("hello\n");
return 0;
}

return 0 is the default in C99, but you should still put it in.

Well, it looks fine with getchar().

Code:

---

#include <stdio.h>

int main(void) {
    printf("Hello, World!\n");
    getchar();
    return 0;
}

> and i am using Miracle C compiler
Get a real compiler - say dev-c++.
Search the board, this compiler is a big pile of ........ - it doesn't deserve the name "C compiler".

If your homework was "write a C compiler", then miracle C would be a passable first attempt.
As a working compiler for getting real work done, forget it.

Try Dev-C++, it's a much better compiler.

<pedantic>Dev-C++ is an Integrated Development Environment, not a compiler. The compiler it defaults to/is bundled with is mingw, which is a Win32 version of gcc.</pedantic>
