Don't you just hate it when using a tutorial and the instructor tells you to install his fave ide!!
as if it's going to make everything easier

My lecturer at uni told us to use DevCpp. Why.

To play devils advocate: It's a pain in the ass to have 30 students per class all come to you, "uh Professor Derp? Yeah I can't build the project you gave us for this assignment." Because every student has a different setup. Visa-versa; you have to figure out why the submitted assignments won't compile because Student A did what you said, but Student B did his own thing but compiled it on mac which has different libraries yadayada.

But forcing you to use DevCpp? what a sadistic fuck

If I were a teacher I would do this:

Here's my setup; use it or don't, but when you turn in the assignments I damnwell shouldn't have to spend 2 minutes monkeying with the linker.

Not nearly as much of an issues after you get past the 101 classes.

PS: there should be a class covering a wide range of IDEs, Build Chains, compilers, etc

Yes, and like 7 exercises had to be in one file with 7 functions. :')
