can't run program in RedHat

Question

I wrote some simple program

int main(){
              printf("hello word!");
              return 0;
}

I compiled it using gcc -o hello hello.c (no errors) but when I run it in terminal using ./hello I see nothing, why? thanks in advance

Answer 1

Could be the missing newline, so that the output is mangled with the next prompt.

Try:

printf("hello world\n");

this version also uses a more conventional message.
