Great for working through some quick snippet testing on the go and have a keyboard attached to your tablet. However, I must say there it is lacking in customization as far as the editor configuration goes. There is no IDE auto completion support so be willing to code from memory. ### 3/5 — 不是C99标准 *2020-07-03* 难受，用不了uthash ### 5/5 — 很好用但是！？ *2020-04-04* 没有math.h？？？？？ ### 1/5 — App fecha ao executar código simples *2020-03-21* O App fecha automaticamente ao executar um simples código com vetor . Comprei e até o momento está péssimo ### 4/5 — Buona e funziona senza rete *2020-03-05, version 1.3.1* Fatta bene, l’unica pecca e che dopo aver scritto e compilato il primo programma da subito la notifica di acquistare l’app pero’ poi sta continuando a funzionare senza troppi pop up ### 5/5 — Excellent. *2019-06-25* Simple, no nonsense, does what it says! This is all I need to test out code while I’m learning. ### 5/5 — 可以运行 *2019-04-01* 好！ ### 1/5 — 名字骗人 *2019-01-01* 为什么既然之后要收费为什么这个名字写free而不是demo。。 ## Frequently asked questions about C Compiler Free (Offline, Debug) ### Does C Compiler Free have ads?
