[英]passing an array of structs to a function in c++
I have already written a program that in functioning properly.我已经编写了一个运行正常的程序。 I need to break it off into functions.
我需要把它分解成函数。 I have 3 arrays of structs.
我有 3 个结构数组。 I would like to make a function that reads the information from the file and echoprints it out.
我想做一个从文件中读取信息并将其回显出来的函数。 I just need an example on how I would pass it.
我只需要一个关于如何通过它的例子。 I would post my code but I do not want the other students to take it.
我会发布我的代码,但我不希望其他学生接受它。 Thanks.
谢谢。
If you are using C arrays:如果您使用 C 数组:
struct A { int v; }
A data[10];
void func(A *array, size_t n) {
}
func(data, 10);
Or if you are using a vector:或者,如果您使用的是向量:
std::vector<A> vec;
void func(std::vector<A>& array) {
}
func(vec);
Since you are tagging this as "C++", I assume you are using vectors ( :-) )由于您将其标记为“C++”,因此我假设您使用的是向量(:-))
void f1 ( yourVector& yourVector )
{
// do something with the vector as read-write (for example fill the vector with somthing).
}
void f2 ( const yourVector& yourVector )
{
// do something with the vector as read-only.
}
int main()
{
std::vector <yourStruct> yourVector;
f1( yourVector );
f2( yourVector );
return 0;
}
