how do i create a make file in windows operating system and run it using cmd : i am new to makefile concept
so to try out if i am able to run and compile c files using word "make"in command prompt i made   main.c (which contains main function)  ,ttt.c   (which contain a function void ttt(int)) ,  mandar.h  (headerfile to include void ttt(int) function in main.c)
when i run this program in cmd using "gcc main.c ttt.c -o main && main",program gets compiled and run properly(so there shouldn't be any error in code)

now in the same directory i made a file Makefile.txt as follow

now when i type "make "in cmd following message is shown
[image of cmd message][2]

i typed everything exactly the same way as in "head first c " book
did i miss something 
this is my first time to ask a question so suggestion regarding improvement of questions are also welcomed
