Where is ncurses.h? SOLVED

After my operating system hit 100% used, I installed Mx Linux and now it is only using 10%. I tried to compile one of my programs and it could not find ncurses.h. I did a search in the file system but could not find it or curses.h. I did find libncurses,so and libncurses,so.6.4
SOLVED: Code:sudo apt-get install libncurses-dev installed ncurses.h which is a link to curses.h.
