I'm not sure why this code isn't working?-CodePudding

#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;
}

I tried running this code but I am getting these errors while trying to do so:

DealOrNoDeal.cpp:7:34: error: no member named 'tuple' in namespace 'std'

Which was really strange because I never had a problem with this code segment before... I am trying to build a deal or no deal game, but all it does is bringing multiple errors. Any ideas on how I can fix this?

CodePudding user response：

The errors you are getting are because you are using the wrong version of C .

The std::tuple template was added in C 11.

To fix this error, I recommend changing the C version in your compiler's config. I use msys64 mingw64 g in VSC and can compile this code without errors.

How to install: https://code.visualstudio.com/docs/cpp/config-mingw

You can also tell clang to compile with this option: -std=c 11

CodePudding user response：

Thanks anyways, I simply used this command instead to get my code working:

clang   -std=c  11 -stdlib=libc   DealOrNoDeal.cpp

I tried following the steps the other mentioned but couldn't do it cause microsoft windows applications cannot be opened with MacOS.
