Conflict in GCC version display

In Linux machine, multiple versions of GCC are currently installed. To find out the current GCC version the below command is executed.

$ gcc --version

It displayed,
gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-4)

When the command 'gcc --version' is executed through a shell script, it is displaying a different gcc version.

The script content: 

VERSION=$(gcc --version)
echo ${VERSION}

The display is, gcc (GCC) 4.8.2 Copyright (C) 2013 Free Software Foundation, Inc.

If the same shell contents are executed on command line it is showing different version of GCC.

$VERSION=$(gcc --version)
$echo ${VERSION}

It shows,
gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-4)

For the same command, it is displaying two different version of GCC, strangely. What could be cause of conflict?

It is very possible that your current shell and your script using different setting of PATH. If you put a echo $PATH before both your gcc --version command, you will see the difference.
