Full Discussion: Why the results of these two code fragments are not the same?
Top Forums Shell Programming and Scripting Why the results of these two code fragments are not the same? Post 303030166 by johnprogrammer on Wednesday 6th of February 2019 11:09:03 PM

The POSIX shell code detects if there are two or more, same command line arguments to the script.


An example with C++03.

Assuming we have a vector (array) with some strings:

Code:
#include <iostream>
#include <string>
#include <vector>


int main()
{
  using namespace std;

  string stringArray[]={"some", "to", "words", "to", "use", "for", "testing", "purposes"};

  vector<string> myvector(stringArray, stringArray+ sizeof(stringArray)/sizeof(*stringArray) );


  Here is the interesting part:

  for(vector<string>::size_type i= 0; i< myvector.size(); ++i)
  {
    for(vector<string>::size_type j= i+ 1; j< myvector.size(); ++j)
    {
       if(myvector[j]== myvector[i])
       {
         cout<< "Two or more words are the same\n\n";
         
         return 0;
       }
    }
  }

}

This is what I am trying to do with the POSIX shell code I posted.
