The.h files are used to expose the api of a program to either other part of that program or other program is you are creating a library For example, the program pizzadelivery could have 1.c file with the main program, and 1.c file with utility functions. I've always used a *.h file for my class definitions, but after reading some boost library code, i realised they all use *.hpp I've always had an aversion to that file extension, i think mainly be. #ifndef my_header_h #define my_header_h #include <stdio.h> void dostuffwith(file *f) // need the definition of file from stdio.h #endif if header a depends on header b such as the example above, then header a should include header b directly
Do not try to order your includes in the.c file to satisfy dependencies (that is, including header b before header a) That is a big ol' pile of. В чем разница между файлами с расширениями .h и .hpp в C++? Что лучше использовать? 看国外电视新闻、视频会发现99%的英语母语者读Huawei就是“娃为”，以至于有华为粉丝宣称这是华为官方钦定的标准发音。 当英语里h在中间时候也一样，例如Did he？ h是几乎完全脱落的。 但汉语里绝对不能弱化，否则“你好”会变成类似“尿”，“米好”会变. 知乎，中文互联网高质量的问答社区和创作者聚集的原创内容平台，于 2011 年 1 月正式上线，以「让人们更好的分享知识、经验和见解，找到自己的解答」为品牌使命。知乎凭借认真、专业、友善的社区氛围、独特的产品机制以及结构化和易获得的优质内容，聚集了中文互联网科技、商业、影视. When dividing your code up into multiple files, what exactly should go into an.h file and what should go into a.cpp file?
.cpp files, or implementation files, are used to actually implement those methods and use those instance variables The reason they are separate is because.h files aren't compiled into binary code while.cpp files are.
