the code above made simulate car making decisions in video game.

at intersection, 40 % of time car turn left, 30% right, 20% straight, , 10% of time car explode.

the program executes 10,000 of these decisions , outputs results.

everything works great except function "getcount()". function, when called, supposed generate random numbers representing decisions , store amount of times each numbers generated in array.

however, when compile program, error saying:

"in line 21, expected primary-expression before ']' token". 

this same line call function. have tried few things try , fix keep getting error.

any advice appreciated, thank you.

getcount( int count[] ); 

should be

getcount(count); 

the type doesn't have repeated; compiler knows count same variable declared int[].
