running simple C programs

[JPotter]

I appologize for the extreme simplicity of this question, but I find any similar posts. I switched over to Ubuntu Linux over the Winter, and I am commited to use it as much as I can. I am taking an advanced C programming course this quarter, and I thought gcc would be great! I only have one, rather pressing, problem. I can't figure out how to get the output from my programs.

after compilation using


gcc -Wall -o hello_world hello_world.c


#include <stdio.h>

int main()
{
printf("%s","Hello World!");
return 0;
}

I tried to run the program by typing in the output file's name, but I get:


bash: hello_world: command not found

so . . . if you don't want to read the top, the question is: How do I run this program, and see the output?

The current directory is not in the "path" variable for security reasons. So you need to explicitly give the whole path to the executable, by using "." for "current directory".



./your_binary
