Tried better implementation in C99

Here is the code:

/*
 * miajlqt.c
 *
 * coded in C99, I think
 *
 * coded in 2020-01-26, around 00:10 (JST/UTC+8)
 *
 * coded by User:YamTokTpaFa
 * <https://esolangs.org/wiki/User:YamTokTpaFa>
 *
 * This is an implementation of an interpreter
 * for an esoteric programming language
 * 'If(j)invert()if(l)change()if(q)input()if(t)output(x)
;'
 *
 * The information of the language can be found below:
 * <https://esolangs.org/wiki/If(j)invert()if(l)change()
if(q)input()if(t)output(x);>
 *
 * I, YamTok, would like to publish this code under
 * public domain, but how am I supposed to do so?
 *
 * USAGE
 *      this-program your-program-file

I tested with three Hello World programs. Is this what you expected? --YamTokTpaFa (talk) 15:19, 25 January 2020 (UTC)
