(prime.cpp) A prime number is a number that cannot be formed by multiplying two smaller numbers (not including 1). For example, 2, 3, 5 are prime numbers but 4 (2*2) and 6 (2*3) are not. Write a C++ program that receives the start point and end point from user and displays all the prime numbers in this range. The program also receives how many numbers to display per row. No need to validate. Print the results in a tabular format....
