Passing Arrays to function in Visual C++
 

This seems like a simple task but the microsoft visual c++ 6.0 compiler is giving me a problem with this. Its complaining about the lines where i try to use a passed array such as "fin[i]=0".

Its giving this error for the following code.

"error C2109: subscript requires array or pointer type"

void main()

{





///// data structures for banker's //////////////////



//avaliable resources, actually only one, which is bank's Money.

int r_avaliable;                

int curr_allocation[NUM_PROCESSES];        //current allocation of resources (money) to each Process (Client)

int max[NUM_PROCESSES];                                //max demand of each process

int need[NUM_PROCESSES];                                //remaining resource need of each process



int request[NUM_PROCESSES];         //requests of clients for money.



//used for safety algorithm

int finish[NUM_PROCESSES];



int ret;

ret = safety(r_avaliable, need, finish);



} //end Main ()











int safety (int ava, int nd[], int fin[])

{



        //initialize work to avaliable, using ava so, OK.

        //initialize finish[i]= false for all i =1,2,3,etc..

        for (int i=0; i<=NUM_PROCESSES; i++)

        {

        fin[i]=0; 

        }



        //find i such that both,

        //finish[i]= false and

        //Needi <= Work (avaliable)



        for (int j=0; j <=NUM_PROCESSES; j++)

        {

                //look for an unmarked process

                if ((fin[j]==false) &&  (nd[j] < ava[1]))

                {

                        //if found

                        //A = A+Ci 

                        //Ci = 0;

                }



                //else

                else 

                {

                        //loop = false

                }



        } //end for



return 1;

} //end safety



//function prototypes

bool safety(int , int [NUM_PROCESSES] , int [NUM_PROCESSES]);

Re: Passing Arrays to function in Visual C++
 

nevermind i figured out the problem.

if ((fin[j]==false) && (nd[j] < ava[1]))

I changed ava to an int instead of an array of ints. So it should look like this:

if ((fin[j]==false) && (nd[j] < ava))


thanks anyways..

Re: Passing Arrays to function in Visual C++
 

Your function definition declares "ava" as an it, but your trying to use as if it was an array. This wasn't too hard to spot, but in the furture please include everything so it can be pasted into compiler without modification.
