My code does not work, there are many compiling errors and this I know I messed up on incorporating the functions alongside my filling system code

#include <iostream> //library for input output stream
#include <fstream> //library for reading and writing files
#include <assert.h> //for the assert function
using namespace std;

struct Components //Components variable has all the variables relating to the Component of the Quiz
{
    string name,done;
    int score;
    int TotalScore = score;
    char ans1,ans2,ans3,ans4,ans5,ans6;
    ofstream fout;
};

void GetInfo(Components &variables);

void AnswerSheet(Components &variables);
