Cygwin Not Showing Any Output in C

I wrote this code in Sublime:

int main (int argc, char **argv){    printf("Hello World");    return 0;}

Saved it at C:\cygwin64\home\debol as helloworld.c.

Typed in this on Cygwin64 Terminal:$ gcc -o helloworld helloworld.c

But I'm not seeing any output. Please help.
