Topic: pointers, dynamic array and command line arguments

Write a complete C++ program named “showHelp” that accepts command line arguments. 
It checks whether there is a command line argument of “/help” or
“/?” or “-help” followed by a topic number. 

It will print out “yes, topic number(<number>) if there is one. 
Otherwise, it prints out “no, topic number(N/A) 

For example, if you run this program with correct arguments as follows, it will
print out yes and its associated topic number respectively
showHelp /? 101
showHelp /debug /help 102
showHelp /print /help 103 /verbose
showHelp -verbose -debug -help

And if you run the program with invalid arguments, it will print no, in all cases
showHelp -help
showHelp 101 /?
showHelp 101 102 /help /verbose
showHelp /? /help -help
Note: command line arguments are simply an array of pointers to C-string.

 

example code:

#include <iostream>
using namespace std;
 
int main(int argc, char** argv){...}
