Write a function template for a function that has parameters for a partiallyfilled array and for a value of the base type of the array. If the value is inthe partially filled array, then the function returns the index of the firstindexed variable that contains the value. If the value is not in the array, thefunction returns −1. The base type of the array is a type parameter. Noticethat you need two parameters to give the partially filled array: one for thearray and one for the number of indexed variables used. Also, write asuitable test program to test this function template.
