Answer 3

Are you aware of your compilation errors?

Answer 4

theres no error when compilation

Answer 5

Well this is what I got when I tried,

prog.cpp: In function ‘int main()’:

Answer 6

what is this visual basic?

Answer 7

C++

Answer 8

i'm using c not c+++

Answer 9

you declared
int passanger();
but you defined
int passanger(y)

They are inconsistent, and the version with the y doesn't give y's type (e. g. int)

They should both be e. g. int passanger(int y)

also, passenger is spelled with an e (but the compiler doesn't care)

Answer 10

in addition, you're using some function "system" which you haven't declared.

The rest are just warnings.
