Length of an `int` array in Objective C

I am passing an Integer array to a function. Next I want to traverse through the array. In C and C++ this worked by simply using arrayname.length which gave the number of elements in array. What is the way to find that in Objective-C?

[NSArrayObject length] works for NSArray type but I want it for int[]. Not even [XYZ count] works (an already suggested answer) so I'm looking for another way here.

this code can be use when the total number of element in array are not known.

main()
{
    int a[]={1,2,3,4,5,6,7}
    int i;
    clrscr();
    for (i=0;i<=((sizeof(a)/sizeof(int));i++)
    {
        puts(a[i]);
    }
    getch();
}

You should try the following approach:

float ptArray[] = {97.8, 92.3, 89.4, 85.7, 81.0, 73.4, 53.0, 42.3, 29.4, 14.1};

int x = sizeof(ptArray)/sizeof(ptArray[0]);

 NSLog(@"array count = %d", x);

Output:

array count = 10
