System()

[Tristan101]

Ive been reading around this forum and noticing everyone saying system commands are bad so is there any way on windows to clear your screen without using system("CLS") because i need to clear the screen in some parts of my program

thanks

Not every one. There is nothing inherently bad about std::system(); but it has to be used with care. It has the same kind of risks that fork()/exec()/CreateProcess or using a shared library (.so/.dll) have.

Yes, 'Do not call system() if you do not need a command processor'.

and: 'Sanitize the environment when invoking external programs'
