Here is a working version of your code
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;
}
