 we can also reverse the process.*/

how to activate graphics library in Turbo C++IDE

how to activate graphics library in Turbo C++IDE

 follow the steps given here:

step1) open turbo c++ IDE

          

step 2)  click options

             

step 3) click linker and then  library

step 4) click library and check out graphics library

done!!!

now you can start writing code using graphics.h
