+
+## Task:
+
+Your job is to write a function, which takes three integers `a`, `b`, and `c` as arguments, and returns `True` if
+exactly two of the three integers are positive numbers (greater than zero), and `False` - otherwise.
+
+## Examples:
+
+```
+twoArePositive(2, 4, -3) == true
+twoArePositive(-4, 6, 8) == true
+twoArePositive(4, -6, 9) == true
+twoArePositive(-4, 6, 0) == false
+twoArePositive(4, 6, 10) == false
+twoArePositive(-14, -3, -4) == false
+```
