Some times c language does not work on vista/7 32/64 bit windows versions.
In this tutorial I will teach you how to run c++ in these operating system
For this you will need these two following things

Download and extract TC folder to C drive













download and install Dos box

Run dosbox

Now type this command mount c c:\ and then enter
You got some error Mounting c:\ is not recommended like this. Ignore it

now type the command c: then enter

cd tc\bin enter














now type tc and press enter

see the magic

for full screen press alt+enter

you have to use all these commands every time you run dos box But I have an solution click start button, all programs, dosbox-0.74 then option Open dos box option as shown in picture below

now go to the bottom of the file now type the line which highlighted in red color in the picture below



save it and then restart dosbox again
