// positive integers in an array

int countPositiveNumbers(int* arr, int n)

{

int pos_count = 0;

int i;

for (i = 0; i < n; i++) {

if (arr[i] > 0)

pos_count++;

}

return pos_count;

}

{

int arr[] = { 2, -1, 5, 6, 0, -3 };

int n;

n = sizeof(arr) / sizeof(arr[0]);

printArray(arr, n);

printf("Count of Positive elements = %d\n",

countPositiveNumbers(arr, n));

return 0;
