In C programming, a struct (short for "structure") is a user-defined data type that allows grouping variables of different data types under one name. Initializing a struct properly ensures that all its members have predictable values when used. There are several ways to initialize a struct in...

然而,我们也可以这样来初始化一个结构体变量:创建一个函数,比如叫 initializeStruct,可以为每一个传递给它的结构体做初始化,这样就方便很多,特别是当结构体中的变量很多时。 之前指针那一章我们也已经学了,如果我们对函数传递普通变量,那么因为 C语言的函数参数传递方式是值传递,所以它会对传给它的函数参数做一份...
