Error with strcoll (C++) - c++

Question

I want to sort a vector of strings into order alphabetically. I have coded thus far and I can not resolve the error for strcoll. Also, I am not allowed to use algorithm library. The error can be seen in the bubbub function where I am trying to bubble sort.
I have a few functions that should explain themselves with their names
#include <iostream>
#include <string.h>
#include <vector>
#include <stdio.h>
using namespace std;
inline void swap(string & a, string & b)
{
string c = b;
b = a;
a = c;
return;
}
void input_name(string&);
void sort_names(string&);
void repeat_pro(int&);
void sortArray(string, int);
void print_names(vector<string>& b_list);
void bubbub(vector<string> & b_list);
int main() {
vector<string> b_list;
string name;
int choice;
int count=0;
cout << "Welcome to the Business Sorting Program!" << endl;
do{
input_name(name);
b_list.push_back(name);
count++;
repeat_pro(choice);
bubbub(b_list);
cout<<"\n \n Your Businesses are:"<<endl;
for(int i=0; i < b_list.size() ; i++){
cout<<b_list[i]<<"\n";
}
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');
for (int x=0; x<answ.size(); x++){
answ[x] = tolower(answ[x]);
}
if (answ == "yes" || answ == "y"){
choice = 0;
}
else {
choice = 1;
}
}
void bubbub(vector<string> & b_list)
{
vector<string>::size_type loop = 0;
bool done = false;
while ((loop+1 < b_list.size()) && ! done)
{
done = true;
for (vector<string>::size_type count = 0;
count+1 != b_list.size(); count++)
{
string x;
string z;
x = b_list[count];
z= b_list[count+1];
if ( strcoll (x,z) < 0 )
{
swap( b_list[count], b_list[count+1] ); // swap
done = false;
}
}
loop++;
}
return;
}

Answer 1

I fixed it by converting my string into a list of chars. then compared them and swapped the vector based on the results. Thanks for the help guys
void bubbub(vector<string> & b_list)
{
vector<string>::size_type loop = 0;
bool done = false;
while ((loop+1 < b_list.size()) && ! done)
{
done = true;
for (vector<string>::size_type count = 0;
count+1 != b_list.size(); count++)
{
string x;
string z;
char array[50];
char array2[50];
x = b_list[count];
z= b_list[count+1];
strncpy(array, x.c_str(), sizeof(x));
strncpy(array2, z.c_str(), sizeof(z));
if ( strcoll (array,array2) > 0 )
{
swap(b_list[count+1], b_list[count] ); // swap
done = false;
}
}
loop++;
}
return;
}

You can use std::string::compare instead of strcoll
#include <iostream>
#include <vector>
#include <stdio.h>
#include <cstring>
using namespace std;
inline void swap(string & a, string & b)
{
string c = b;
b = a;
a = c;
return;
}
void input_name(string&);
void sort_names(string&);
void repeat_pro(int&);
void sortArray(string, int);
void print_names(vector<string>& b_list);
void bubbub(vector<string> & b_list);
int main() {
vector<string> b_list;
string name;
int choice;
int count=0;
cout << "Welcome to the Business Sorting Program!" << endl;
do{
input_name(name);
b_list.push_back(name);
count++;
repeat_pro(choice);
bubbub(b_list);
cout<<"\n \n Your Businesses are:"<<endl;
for(int i=0; i < b_list.size() ; i++){
cout<<b_list[i]<<"\n";
}
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');
for (int x=0; x<answ.size(); x++){
answ[x] = tolower(answ[x]);
}
if (answ == "yes" || answ == "y"){
choice = 0;
}
else {
choice = 1;
}
}
void bubbub(vector<string> & b_list)
{
vector<string>::size_type loop = 0;
bool done = false;
while ((loop+1 < b_list.size()) && ! done)
{
done = true;
for (vector<string>::size_type count = 0;
count+1 != b_list.size(); count++)
{
string x;
string z;
x = b_list[count];
z = b_list[count+1];
if (z.compare(x) != 0 )
{
swap( b_list[count], b_list[count+1] ); // swap
done = false;
}
}
loop++;
}
return;
}
Output
Welcome to the Business Sorting Program!
Enter in the name of the business: hello
Do you want to enter in more names: yes
Your Businesses are:
hello
Enter in the name of the business: apple
Do you want to enter in more names: no
Your Businesses are:
apple
hello
Thanks for using this program
