# C语言程序设计 vs 数据结构与算法

The clearest difference is iOS requirement: 数据结构与算法 at 9.0 against C语言程序设计's 12.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. C语言程序设计 sells 1 one-off in-app purchase and 数据结构与算法 sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
