newbie question

[[Deleted]]

my code:

double a[];

a[1]=1.0;

a[2]=2.0;

Print("a1: "+a[1]);

Print("a2: "+a[2]);

it shows a1: 0.000000000000000 and a2: 0.000000000000000...

what's wrong with the code? i was expected to have a1: 1.0 and a2: 2.0...

You need to specify the size.

void start(){
    double a[3];
    a[1]=1.0;
    a[2]=2.0;
    Alert("a1: "+a[1]);
    Alert("a2: "+a[2]);
}

Thanks for your prompt answer, actually i have problems to declare the array size:

extern int arrayNumber=3;

void start() {

double a[arrayNumber];

a[1]=1.0;

a[2]=2.0;

Alert("a1: "+a[1]);

Alert("a2: "+a[2]);

}

it only works when i specify the array size with actual number instead of passing an integer variable...how can i solve this problem?

If you need to change the size of an array use . . .

ArrayResize( object&array[], int new_size) 

extern int arrayNumber=3;

void start() {

double a[1];

ArrayResize( a, arrayNumber );

a[1]=1.0;

a[2]=2.0;

Alert("a1: "+a[1]);

Alert("a2: "+a[2]);

}
