《Programming Abstractions In C》學(xué)習(xí)第54天，p138，總結(jié)如下：

一、技術(shù)總結(jié)

1.stdio.h

3.4小節(jié)介紹“The standard I/O library”，涉及I/O操作最常用的接口是stdio.h，我們經(jīng)常用到里面的printf函數(shù)。

p138。

3.text file

p138, When you use a file to store data for use by a program, that file usually consist of text and is therefore called a text file。You can think of a text file as a sequence of characters stored in a permanent medium and identified by a file name。

3.cohesive什么意思？
