Character dispaying - c++

Question

I know this maybe such a wierd question but it stucks me for a couple of days ago. My assignemnt is to display the students' information and update them using STRUCT type. Here is my works:
#include <iostream>
using namespace std;
struct DATE
{
int day;
int month;
int year;
};
struct STUDENT{
char ID[8];
char name[50];
DATE birthday;
char address[100];
float Math;
float English;
float CS;
};
void inputClass(STUDENT* &list, int &n)
{
cout << "Please enter the number of students: ";
cin >> n;
list = new STUDENT[n+1];
for(int i=1; i<=n; i++)
{
cout << "Please enter the info of student " << i << endl;
cout << "ID: ";
cin >> (&list[i]) -> ID; //the same with "list[i].ID"
fflush(stdin);
cout << "Name: ";
cin >> (&list[i]) -> name;
fflush(stdin);
cout << "Date of Birth\n";
cout << "Day: ";
cin >> (&list[i]) -> birthday.day;
fflush(stdin);
cout << "Month: ";
cin >> (&list[i]) -> birthday.month;
fflush(stdin);
cout << "Year: ";
cin >> (&list[i]) -> birthday.year;
fflush(stdin);
cout << "Address: ";
cin >> (&list[i]) -> address;
fflush(stdin);
cout << "Math result: ";
cin >> (&list[i]) -> Math;
fflush(stdin);
cout << "English result: ";
cin >> (&list[i]) -> English;
fflush(stdin);
cout << "CS result: ";
cin >> (&list[i]) -> CS;
fflush(stdin);
cout << "************* Next Student *************\n" ;
}
}
void updateScore(STUDENT* list, int n)
{
cout << "Who do you want to update?" << endl;
cout << "Ordinal Number(s): ";
cin >> n;
//Display outdated results
cout << "Student's Name: " << (&list[n])-> name << endl;
cout << "*********** Current Results ***********" << endl;
cout << "Math: " << (&list[n]) -> Math << endl;
cout << "English: " << (&list[n]) -> English << endl;
cout << "CS: " << (&list[n]) -> CS << endl;
//Update results
cout << "Please update the results" << endl;
cout << "Math result: ";
cin >> (&list[n]) -> Math;
fflush(stdin);
cout << "English result: ";
cin >> (&list[n]) -> English;
fflush(stdin);
cout << "CS result: ";
cin >> (&list[]) -> CS;
fflush(stdin);
}
void main()
{
STUDENT* list;
int n;
inputClass(list, n);
updateScore(list, n);
}
In the "//Display outdated result" section, I used "cout" to print out the Name of the regarding student based on his/her ordinal numbers. However, let's say I want to get the whole name like: "John Smith". What I have got, however, is only "John". Is there a way I can get all of the characters?
Many thanks for your help and sorry for my bad English, I am a student from Vietnam.

Answer 1

Use std::getline from the <string> header, with a std::string variable, instead of >> and raw character array.
The >> reads whitespace-separated words of input.
The raw character array doesn't adjust to the needed length, and you risk Undefined Behavior on buffer overflow.
In passing, many/most programmers find all UPPERCASE to be an eyesore; it hurts the eyes.
Also, all uppercase is by convention (in C and C++) reserved for macro names.

Answer 2

As it's already been answered previously, you should use std::getline (refer to this question).
I'm assuming you're using a IDE, and it usually fixes a lot of things for us, users, but this may turn your code non-compilable in other compilers, so there are some things you should fix to be able to compile your code everywhere:
Always pay attention if you're adding the necessary includes. There's lack of an include statement for stdin and fflush. You should add:
#include <cstdio>
Also, main should return an int, so, it should have been something like
int main(int argc, char* argv[]){ /*Although you can usually omit the parameters*/
// Code
return 0;
}
By the way, just as a side comment, you forgot the subscript at:
cout << "CS result: ";
cin >> (&list[]) -> CS;
