[英]I'm trying to sum up the numbers in a given array, using recursion , tried this code but it isn't working. Why?
[英]I'm not sure why this code isn't working?
#include <iostream>
#include <string>
#include <vector>
#include <cstdlib>
#include <ctime>
#include <tuple>
void printBoard(std::vector<std::tuple<int,int>> x) {
for (unsigned int i = 0; i < x.size(); i++) {
int trying = std::get<0>(x[i]);
int num = std::get<1>(x[i]);
std::cout << "Case #" << trying << ", Val = $" << num << std::endl;
}
}
int main()
{
std::cout << 5 << std::endl;
}
我尝试运行此代码,但在尝试这样做时遇到了这些错误:
DealOrNoDeal.cpp:7:34: error: no member named 'tuple' in namespace 'std'
void printBoard(std::vector<std::tuple<int,int>> x) {
~~~~~^
DealOrNoDeal.cpp:7:43: error: expected '(' for function-style cast or type construction

这真的很奇怪,因为我之前从未遇到过这个代码段的问题......我正在尝试建立一个交易或不交易的游戏,但它所做的只是带来多个错误。 关于如何解决这个问题的任何想法?
您遇到的错误是因为您使用了错误的 C++ 版本。
在 C++11 中添加了std::tuple
模板。
要修复此错误,我建议更改编译器配置中的 C++ 版本。 我在 VSC 中使用 msys64 mingw64 g++ 并且可以无错误地编译此代码。
如何安装: https ://code.visualstudio.com/docs/cpp/config-mingw
您还可以告诉 clang 使用此选项进行编译: -std=c++11
无论如何,谢谢,我只是使用这个命令来让我的代码工作:
clang++ -std=c++11 -stdlib=libc++ DealOrNoDeal.cpp
我尝试按照其他提到的步骤进行操作,但无法使用 MacOS 打开 Microsoft Windows 应用程序。
