# Answer to Question #40125 in C++ for Mary

Question #40125

Write, compile, execute, and test a program that uses the function templates

Square(),Power(),and Find() of Exercises 1,2,and 3.

1. Write a function template Square()that returns the square of its only argument.

2. Write a function template Power() that takes two arguments.The first argument

should be of arbitrary type. The second argument is an integer. The function

should return the first argument raised to the power indicated by its second argu-

ment.The return type should be that of its first argument.

3. Write a function template Find() that takes two arguments and returns an inte-

ger.The first argument is an array of arbitrary type.The second argument is an

ordinary variable of the same type as the first argument.The function should re-

turn the array subscript of the first array element that exceeds the second argu-

ment.If no such element is found,the function should return –1.
