LinuxQuestions.org - What package has simple functions like printf & malloc?

Hi. I just installed Ubuntu and tried to compile something using gcc compiler. this is what I got:

Code:

gcc -Wall -g -c cli_fragment.c -o cli_fragment.o

cli_fragment.c:1:19: error: stdio.h: No such file or directory

cli_fragment.c:2:20: error: malloc.h: No such file or directory

Just want to know what package I have to install which has all these function in it. thanks!
