title: Open an .exe file without knowing the full path in C++
body: <p>I want to create a program that opens another <code>.exe</code> file in C++, I want the program to be able to run from any directory, so I will not know the full address of the file.</p>
  
  <p>Eg-<br>
  The Program that I make will be present in a folder, which in turn has  subfolders, which further contains <code>javaportable.exe</code>. I want the program to run the above mentioned <code>.exe</code> without getting the full path. Something like cd operator in normal DOS navigation. Also, if it is possible, I want to select another <code>.exe</code>, which will run through <code>javaportable.exe</code>, and is present in the previous folder.</p>
