te file db.txt is about 4500 lines of code, but i took a few pics for at least an exapmle of what it is.
some examples:
Movie search by characters. Enter two characters.\n
TmENTER
Movies that start with Tm\n
Tmima ithon\n
Tmima ithon\n
Tmima ithon\n
Tmunot Yafo'iyot\n
Tmunot Yafo'iyot\n
Number of matches: 5\n
Test Case 2
MtENTER
Movies that start with Mt\n
Mtv Base: Touching Base\n
Mtvris gemo\n
Number of matches: 2\n
