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() 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 using namespace std; int main(int argc, char** argv){...}
Topic: pointers, dynamic array and command line arguments
Write a complete C++
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.
