CS156: Intro to C, Part I
Spring 2018
Homework #0: Say Hello
The purpose of this assignment is to make sure that you can login
to a Linux system and use the checkin program.
This way, you’re sure that your login and password work
before you need them for homework #1.
This assignment is not optional.
1) Log on to a CS Department Linux system. Use an editor to create a file
called hi.c that contains exactly this (upper/lower case matters):
#include <stdio.h>
int main() {
printf("Hello, CS156 Spring 2018!\n");
return 0;
}
2) Compile & execute your program. My prompt is “%”;
yours will be different. Note the capital W in “-Wall”.
% c11 -Wall hi.c
% ./a.out
Hello, CS156 Spring 2018!
3) Use web checkin, or turn it in like this:
~cs156/bin/checkin HW0 hi.c
