Write a function in C++ that takes an integer argument D and returns the index and value of the first D-digit Lucas number. Turn in a print-out of your code, as well as the index and value your function returns when D = 15. Example) Let D = 3.

Write a function in c using #include <stdio.h> that takes a one-dimensional integer array and returns the index of the first occurance of the smallest value in the array. Your function must be able to process all the elements in the array. Create a function prototype and function definition (after the main function).

Write the following in C: 2. An integer is said to be prime if it is divisible by only 1 and itself. Write a function called prime() that takes in one integer number, and returns 1 (true) if the number is prime and 0 (false) otherwise. Write a program to generate six random numbers between 1 to 100 and calls function prime() on each one to determine if it is prime or not.

Write a method which takes as input an integer, returns true if the integer is prime, and returns false otherwise. Do not import anything. If the input is negative, 0 or 1, false should be returned. If the input x is greater than 1, you can test if it is prime (inefficiently) by checking if it is divisible by any integer from 2 up to half of x. If it is not divisible by any of these numbers, then it...
