How do I pass an argument in C / Bash Scripting?

Hi have an easy C program that does the following when I run it with ./a.out

Please enter your name:

What I want to do, is I want to automatically pass the name without having to wait for the prompt. I tried ./a.out Sam, but it would still prompt for a name. I'm trying to write a bash script that would do that.

Any help would be appreciated. Note: I don't want to modify the C source. All I want to do is be able to pass the first argument without having to wait for the prompt.

The program reads from stdin. You can pipe to stdin:

echo "Sam" | ./a.out
