推荐答案

有很多这个程序的错误。它不会按原样编译。此外，您的代码已丢失其格式，似乎被剪掉。粘贴它时选择C ++代码选项。它没有格式化时很难阅读。



我看到的第一个问题是：

There are LOTS of errors with this program. It will not compile as it is. Also, your code has lost its formatting and appears to be clipped off. When pasting it in select the C++ code option. It is very difficult to read when it has no formatting.

The first problem I see is this :

chrompopcurrent[chromosome_number];

问题是变量没有类型。它似乎是一个数组但是什么类型？这导致了许多其他问题。函数原型似乎将该变量作为参数，但这不是如何编写原型。



看来这里有一个缺少的空间而且它是一个巨大的区别。这可能是由于缺乏格式化但我不知道。



根据这个假设，它应该声明为：

The problem is that variable has no type. It appears to be an array but of what type? That leads to a bunch of other problems. The function prototypes appear to take that variable as an argument but that is not how to write a prototype.

It appears that there is a missing space there and it makes a HUGE difference. This could be a result of a lack of formatting but I don't know.

Under that assumption, it should be declared as :

chrom popcurrent[chromosome_number];

，原型应声明为：

and the prototypes should be declared as :

void* init_pop( chrom popcurrent[] );

请注意，原型或函数定义中不需要数组的大小。该函数是否真的返回指向未知类型的指针？我不知道因为我看不到那段代码。除非你不能这样做，否则最好返回指向已知类型的指针。

Note that the size of the array is not needed in the prototype or in the function definition. Does that function really return a pointer to an unknown type? I don't know because I can't see that code. It's always best to return a pointer to a known type unless you just can't do it.
