reading as numbers and saving as colors

Question

i need to develop a program that writes a color to the screen and each line of another file according to the numbers read from a file. (The file name to be read must be read.txt, write the file name to be written.txt) 0: black 1: blue 2: red 3:green 4:white
I think it will write 0-4 numbers in the read.txt file.
0
1
1
4
etc....

When I run the program it will save in the written.txt file as below.
0: Black
1: Blue
1: Blue
0: Black
4: White
... etc.
I tried to do something, but saves only the first line in the written.txt file

Answer 1
