Sorting string array alphabetically in a 2D array (C++) - c++

Question

I have coded thus far and I am not sure how to sort using the 2-dimensional array. Basically, one function is for sorting an array of strings, another function is for swapping two strings. Any help would be appreciated. (Also I am not allowed to use c++ 11 :/)
#include <iostream>
#include <string>
#include <algorithm>
using namespace std;
void input_name(string&);
void sort_names(string&);
void repeat_pro(int&);
void sortArray(string, int);
int main() {
string b_list[100][2];
string name;
int choice;
int count=0;
cout << "Welcome to the Business Sorting Program!" << endl;
do{
input_name(name);
b_list[count][1] = name;
count++;
repeat_pro(choice);
cout<<"\n \n Your Businesses are:"<<endl;
for(int j=0; j<count; j++){
cout<<b_list[j][1]<<endl;
}
cout << "\n\n";
}while(choice == 0);
cout << "Thanks for using this program"<<endl;
return 0;
}
void input_name(string &name){
cout << "Enter in the name of the business: ";
getline(cin, name);
}
void sort_names(string &name){
}
void repeat_pro(int &choice){
cout << "Do you want to enter in more names: ";
string answ;
cin>>answ;
cin.ignore(1000,'\n');
if (answ == "YES" || answ == "Y" || answ == "yes" || answ == "y"){
choice = 0;
}
else {
choice = 1;
}
}

Answer 1

it is not clear to me from the description what problem the program really tried to solve. I'm assuming it's kind of like a two column spreadsheet, the second column is the name entered by the user(but what is in the first column?).
assume you need to keep the array in sorted order as the data goes in, just do a binary search (you can do a linear search for small dataset like 100 entries).
// we don't have lambda before C++11
struct comparator {
bool operator () (const string (&x)[2], const string (&y)[2]) const {
return x[1] < y[1];
}
};
//... omitted
string data[100][2];
int count = 0;
while (count < 100) {
// no rvalue, move, rvo, etc. before C++11
string name;
input_name(name);
// no type deduction and lambda
string (*position)[2] =
std::lower_bound(&data[0], &data[count], name, comparator());
int index = position - &data[0];
// simulate an vector::insert operation, but for our array
for (int i = count; i > index; --i) {
// before we had move in C++, we would do swap with an empty element.
// in this case, the entry at data[count] is default constructed
std::swap(data[i][1], data[i-1][1]);
}
data[index][1] = name;
}
//... omitted
of course we can use a typedef to make it cleaner, but that's left to you.
