Plz help me make this program in C language.

It should be working under the GCC command.

Write a program called binary_string.c. The content we will input is composed of' X', 'O' and '_'

This program can replace all the input _ with all possible strings consisting of X and O.

Which mean it will prints out all possible binary strings where the '_' be replaced with either X or O. for example: ./binary_string.out O__O OOOO OXOO OXXO OOXO

./binary_string.out X_X_O XXXXO XOXXO XOXOX XXXOX
