Q1 (20 pts). Write a C++ function named countBetween that accepts an integer array, the number of elements in the array, and two integers a and b as a parameter. The function should return the number of values in the array between a and b (inclusive). For instance, running the following code in the main function should print 3,0,2, and 5. int a[]={3,7,9,15,4,6} cout countBetween (a,6,7,4) endl; cout countBetween (a,6,10,14) endl; cout countBetween (a,6,5,8) endl; cout countBetween (a,6,9,2) endl
