C++ list with array of strings - c++

Question

I have to make a list with people and their exam result in C++. My problem is that I don't know how to input the array.
I was trying to make 3D array of strings, but it doesn't works. It must be in function! If you have a better suggestions, I will be very grateful
My input must be something like:
Peter Evens 4.86
*other people**
*average result of the group**
*the one with the heighest grade**
*the one with lowest grade**
This is what I have done for now:
#include <iostream>
#define MAXN 200
#define MAXM 200
#define MAXX 200
using namespace std;
void input(char list[][MAXN][MAXM], int n) {
for (int i = 0; i < n; i++)
for (int j = 0; j < n; j++) {
for (int p = 0; p < n; p++)
cin >> list[i][j][p];
}
}
int main() {
char list[31][MAXN][MAXM];
int n;
cin >> n;
input(list, n);
return 0;
}

Answer 1

You don't need to run the third iteration since you don't have to store the input character by character. The third dimension can be used for storing the entire string.
Try the following way. Observe the corrections i have made in your snippet.
#include <iostream>
#define MAXN 200
#define MAXM 200
#define MAXX 200
using namespace std;
void input(char list[][3][MAXM], int n) {
for (int i = 0; i < n; i++) //number of entries
for (int j = 0; j < 3; j++) { //3 fields - fname, lname and marks
cin >> list[i][j];
}
}
int main() {
char list[31][3][MAXM];
int n;
cin >> n;
input(list, n);
return 0;
}

Answer 2

You must use a vector of struct.
Define your struct this way:
typedef struct details{
string Fname;
string Lname;
float marks;
} details;
And vector should look like
vector< details > info;
I am just showing you how to implement this in the following code:
void insertValues(vector< details >& info){
int n;
details d;
cout<<"Enter the size of record: ";
cin>>n;
cout<<"Enter records: "<<endl;
for(int i=0;i<n;i++){
cin>>d.Fname>>d.Lname>>d.marks;
info.push_back(d);
}
}
void LowestScorer(vector< details > info){
details d;
vector< details >::iterator it=info.begin();
d=*it;
for(;it!=info.end();it++){
if(d.marks > it->marks){
d=*it;
}
}
cout<<"Lowest Scorer: "<<d.Fname<<" "<<d.Lname<<" "<<d.marks<<endl;
}
main should look like this:
int main(){
vector< details > info;
insertValues(info);
LowestScorer(info);
return 0;
}

As mentioned in above comments, it's good time to learn vector. It's very easy. Below is a very simple and neat solution:
#include <iostream>
#include <string>
#include <vector>
using namespace std;
typedef vector<pair<string, string> > Container;
int main()
{
Container container;
container.push_back(make_pair("Peter Evens", "4.86"));
container.push_back(make_pair("Other name", "his score"));
return 0;
}
