具有std :: array的C ++模板函数 [英] C++ template function with std::array

问题描述

我具有以下功能:

template <typename T, size_t SIZE>
void minSortLoop(array<T, SIZE>& a){
    for(size_t o = 0; o < SIZE; o++) {
        size_t minIx = 0;
        for(size_t i = o + 1; i < SIZE; i++) {
            if(a[i] < a[minIx]) {
                minIx = i;
            }
        }
        swap(a[o], a[minIx]);
    }
}

我喜欢从其他位置调用它，

I like to call it from the other location like:

std::array<int, 3> arr = {3,1,-9};
minSortLoop(arr);

但是我得到了错误:

描述资源路径位置类型无效的参数'候选是:void minSortLoop(?&)'Test.cpp/g测试第23行语义错误

Description Resource Path Location Type Invalid arguments ' Candidates are: void minSortLoop(? &) ' Test.cpp /gTest line 23 Semantic Error

描述资源路径位置类型没有匹配的呼叫功能到'minSortLoop(std :: array *)'Test.cpp/g测试第23行C/C ++问题

Description Resource Path Location Type no matching function for call to 'minSortLoop(std::array*)' Test.cpp /gTest line 23 C/C++ Problem

如何正确调用排序函数?

How do I call my sort function correctly ?

最诚挚的问候:-)

PS:不允许使用std :: sort.

PS: I'm not allowed to use std::sort.

我试图通过其他方式通过:

I've tried to pass in other ways like:

std::array<int, 3> arr = {3,1,-9};
minSortLoop(&arr);

有错误:

描述资源路径位置类型无效的参数'候选是:void minSortLoop(?&)'Test.cpp/g测试第23行语义错误

Description Resource Path Location Type Invalid arguments ' Candidates are: void minSortLoop(? &) ' Test.cpp /gTest line 23 Semantic Error

Description Resource Path Location Type no matching function for call to 'minSortLoop(std::array*)' Test.cpp /gTest line 23 C/C++ Problem

和:

std::array<int, 3> arr = {3,1,-9};
minSortLoop(*arr);

有错误:

描述资源路径位置类型无效的参数'候选是:void minSortLoop(?&)'Test.cpp/g测试第23行语义错误

Description Resource Path Location Type Invalid arguments ' Candidates are: void minSortLoop(? &) ' Test.cpp /gTest line 23 Semantic Error

描述资源路径位置类型与操作符*"不匹配(操作数类型为'std :: array')Test.cpp/g测试第23行C/C ++问题

Description Resource Path Location Type no match for 'operator*' (operand type is 'std::array') Test.cpp /gTest line 23 C/C++ Problem

不确定如何称呼它.该参考建议类似于我的第一个示例此处.

Not sure how to call this. The reference suggests something like my first example here.

@tadman:

我需要传递尺寸.这是从任务描述中给出的:-(

I need to pass the size. That's given from the task description :-(

@ Jarod42:这是哪个编译器?我在Windows 7下的Eclipse中使用Cygwin.

@Jarod42: Which compiler is this ? I'm using Cygwin in eclipse under windows 7.

@pasasap:是的，我编译了它，或者至少尝试了.导致描述的错误.

@pasasap: Yes, I compiled it or at least I try. It results in the described errors.

正如@pasasap在评论之一中提到的那样，问题似乎是由于日食引起的.没有人知道解决方案而不关闭cody-analysis吗?

As @pasasap mentioned in one of the comments, it seems like the problem is because of eclipse. Does anyone know a solution without turning off cody-analysis ?

推荐答案

问题是我的IDE Eclipse.一旦我关闭了代码分析功能，它就会按预期进行编译.

The problem is my IDE Eclipse. Once I turned off the code analysis feature it compiled as expected.
