A small project which could encode plain ASCII text to base64 or decode base64 text to plain text.
Coded and tested under macOS 10.13.4(17E199) with Xcode 9.3(9E145), should be compiled by all compiler which support C99 standard(there are initial declarations inside for loop).
一个可以实现将纯ASCII文本转换为base64编码或进行相反转换的小工程.
编程环境为 macOS 10.13.4(17E199) 搭配 Xcode 9.3(9E145), 理论上可被所有支持C99标准的编译器编译(代码中存在for循环中的初始化声明).
