hey guys i need yall to help me to debugg this code i have no idea whats wrong with it.
tried everything pls help!!!

In future, how about a brief description of the *actual problem* in your thread titles. A lot of people won't read "please help" because it's totally over-used.

So... how about you tell us exactly what problems you're having....

[Fader_Berg]

Read the compiler error messages. In this case they would be quite straight forward.

Good luck.

i compiled the code on my machine and there r many problems. here's the compiler's warnings:

cc "C file.c"
C file.c: In function ‘main’:
C file.c:36: error: expected ‘;’ before ‘{’ token
C file.c:60: error: ‘else’ without a previous ‘if’

C file.c: In function ‘search_value’:

i think u should fix those problems first and see if it works.
