What is the use of Cygwin exactly? : <p>I installed Cygwin on my laptop. After going through the instructions on netbeans site, i found that i need to change the path directory. </p>

<p>My path directory initially shows some java thing on that and if i change it then will it create some problem?</p>

<p><strong><em>I basically Want to run C/C++ programs by NetBeans so I installed Cygwin thinking that it would help me. 
Please Suggest me what to do.</em></strong></p>
