C++ 不存在合适的构造函数-Vector

今天我为自己开始了一个简单的编码项目，但我无法找出这个错误，也无法找到解决方法。我遇到的错误发生在我的

do

循环中。更具体地说，它发生在作为参数传递

Nums

的每个函数调用中。错误说明

不存在合适的构造函数，无法将其从“std:：vector[10]”转换为“std:：vector”

在此方面的任何帮助都将不胜感激！蒂亚

没有道理

将函数中需要向量函数参数的类型更改为引用类型，如

int setSize(int size, vector <int> &Nums);
                                  ^^^^^^

调用算法
std:：acculate
后，不会更改变量结果

此外，您正在传递未初始化的变量结果

int result;

你至少应该写信

long long int doMath( const std::vector<int> &Nums )
{
        //Loop through Nums vector and multiply all values
    long long result = std::accumulate(Nums.cbegin(), Nums.cend(), 1ll, std::multiplies<long long>());

    return result;
}

确保函数按预期工作后，可以将其添加到主程序。
这不是C。不要误用标记。
Nums.resize(size);

int setSize(int size, vector <int> &Nums);
                                  ^^^^^^

int doMath(vector <int> Nums, int result)
{
        //Loop through Nums vector and multiply all values
        accumulate(Nums.begin(), Nums.end(), result, multiplies<int>());

        return result;
}

int result;

long long int doMath( const std::vector<int> &Nums )
{
        //Loop through Nums vector and multiply all values
    long long result = std::accumulate(Nums.cbegin(), Nums.cend(), 1ll, std::multiplies<long long>());

    return result;
}

#include <iostream>
#include <vector>

std::vector<int>::size_type setSize( std::vector<int> &Nums )
{
    //Prompt user to enter an integer to establish array size
    std::cout << "How many integers would you like to multiply?: ";

    //Store user input to size
    std::vector<int>::size_type size = 0;
    std::cin >> size;

    //Resize vector to user size
    Nums.resize( size );

    return size;
}

int main() 
{
    std::vector<int> Nums;
    
    auto size = setSize( Nums );
    
    if ( size == Nums.size() )
    {
        std::cout << "The function works correctly.\n";
