Write a program in C++, which has a function to swap/exchange elements of two arrays of type float of size N each. Function is passed pointers of the arrays and their size for processing. Inside the function, use pointer to access elements of arrays. Your program should have the followings: Prototype of the function Definition of the function Two arrays discussed above are declared and initialized in the main() function. Do not take input from keyboard. Call function from main() to exchange elements of arrays Display elements of arrays before and after calling functions
