In the following code fragment:

# include <ios>
# include <fstream>
# include <istream>

using namespace std;
void CommandLine(int argc, char** argv);
int main(int argc, char** argv) {
   CommandLine(argc, argv[]);
   ifstream x.open(argv[1], ios:in);
   ofstream y.open(argv[1], ios::in);
   
   return 0;
};

g++-4 messaging is:
>> g++-4 x.cpp
x.cpp: In function 'int main(int, char**)':
x.cpp:8: error: expected primary-expression before ']' token
x.cpp:10: error: expected primary-expression before ':' token

A recommendation and reason for change is:
1: x.cpp:8 error: illegal to pass an array without subscript value as an 
   argument
   The given message is accurate but non-expressive of the reason
   for failure.
3: cpp:10 error: illegal scope resolution operator ':'
   From memory, there are three uses of ':' in C++
   ':'   label terminator, <label>:
   ':'   case in a switch statement, case <value>:
   ':'   scope resolution operator, "::"
   The given diagnostic message is deceptive.
