- Write a C++ program that will count from 1 to 10 by 1. The default output should be 1, 2, 3, 4, 5, 6 , 7, 8, 9, 10 There should be only a newline after the last number. Each number except the last should be followed by a comma and a space. To make your program more functional, you should parse command line arguments and change behavior based on their values. Argument Parameter Action -f, --first yes, an integer Change place you start counting -l, --last yes, an integer Change place you end counting -s, --skip optional, an integer, 1 if not specified Change the amount you add to the counter each iteration -h, --help none Print a help message including these instructions. -j, --joke none Tell a number based joke. So, if your program is called counter counter -f 10 --last 4 --skip 2 should produce 10, 8, 6, 4 Please use the last supplied argument.
